quantum nonlocality does not exist

An elementary particle can be everywhere at the same time. Analogously, the statistics achievable by separate observers in a quantum theory also happen to be restricted. The relative number of universes in which we would expect to measure aligned spin r times—that is to say, the expected value of the frequency with which we would measure the electron spin to be aligned with the axis of the measuring apparatus—is〈f〉=〈rN〉=∑r=0N(rN)prob(r | N)=∑r=1N(N−1)!(r−1)! Objective Reality Doesn't Exist, Quantum Experiment Shows. The purported mystery of quantum nonlocality lies in trying to understand how particle 2 changes—instantaneously—in response to what has happened in the location of particle 1. For observers who make the decision of which direction to measure the spin in the instant before the measurement, most of the time the two directions will not be the same. Using the MWI, I show that the quantum side of Bell’s inequality, generally believed nonlocal, is really due to a series of three measurements (not two as in the standard, oversimplified analysis), all three of which have only local effects. The first derivation of a non-trivial statistical limit on the set of quantum correlations, due to B. Tsirelson, is known as Tsirelson's bound. The proof depends crucially on the indistinguishability of the initial states of the observers and on the actual existence of the many worlds. According to the right theory – quantum mechanics (e.g. The plane waves are one important and indispensable example, and physicists use various delta function normalizations in this case. Now consider the effect of a measurement on the two-particle system in the Bohm state, that is, with total spin zero. Eq. In the experiment in ref. Enter multiple addresses on separate lines or separate them with commas. In fact, if the measurements are carried out at space–time events that are space-like separated, then there is no Lorentz invariant way of determining which measurement was carried out first. Standard rotation operators for spinor states then give (9)|n^1,↑〉2=(cos⁡θ/2)|n^2,↑〉2+(sin⁡θ/2)|n^2,↓〉2|n^1,↓〉2=−(sin⁡θ/2)|n^2,↑〉2+(cos⁡θ/2)|n^2,↓〉2,which yields|Ψ〉=(1/2)[−(sin⁡θ/2)|n^1,↑〉1|n^2,↑〉2            +(cos⁡θ/2)|n^1,↑〉1|n^2,↓〉2            −(cos⁡θ/2)|n^1,↓〉1|n^2,↑〉2            −(sin⁡θ/2)|n^1,↓〉1|n^2,↓〉2].[11]. 13, pp. Here I directly address Bell’s inequality, which requires a derivation of the Born interpretation of the wave function. Yet, contrary to all our daily experience, there are spatially separated quantum systems that exhibit nonlocal correlations. I do this because many physicists are confused about the meaning of the word probability. However, because of indistinguishability, it is meaningless to say that a particular spin direction is associated with a particular universe. However, for quantum nonlocality problems, the integral of R2 will be finite, and if we pose questions that involve the ratio of the number of effectively distinguishable worlds with a given property to the total number of effectively distinguishable worlds, it is convenient to normalize the spatial integral of R2 to be 1. A comparison of [6] or [7] with [8] shows that if two space-like–separated observers fortuitously happen to measure the spins of the two particles in the same direction—whatever this same direction happens to be—both observers will split into two distinct worlds, and in each world the observers will measure opposite spin projections for the electrons. However, in the MWI, there is no classical regime; the comparison of the data in two macroscopic devices is just as much a quantum interaction as the original setting up of the singlet state. In the Copenhagen interpretation, this third measurement is not considered a quantum measurement at all, because the first measurements are considered as transferring the data from the quantum to the classical regime. performed research and wrote the paper. Locality is restored if observed and observer both obey quantum mechanics, as in the many-worlds interpretation (MWI). quantum field theory where this EPR experiment may be easily embedded), the reason of the correlation(s) is not an action at a distance. In the 19th century, this multiverse nature was ignored. Quantum nonlocality does not exist Frank J. Tipler1 Department of Mathematics, Tulane University, New Orleans, LA 70118 Edited* by John P. Perdew, Temple University, Philadelphia, PA, and approved June 2, 2014 (received for review December 30, 2013) So when the Born interpretation was first presented in the late 1920s, the original Laplacean meaning of probability had been forgotten, and the frequency interpretation of probability was adopted to give a meaning to the square of the modulus of the wave function. Image credit: Anang Dianto (photographer). So the standard argument that quantum phenomena are nonlocal goes like this: (i) Let us add an unmotivated, inconsistent, unobservable, nonlocal process (collapse) to local quantum mechanics; (ii) note that the resulting theory is nonlocal; and (iii) conclude that quantum mechanics is nonlocal. It may appear from Eq. Because the spin of a particle does not exist until a measurement is made, the act of making the measurement and determining the axis of spin of particle 1, will also determine the spin of particle 2, no matter how far apart it is from particle 1. performed research and wrote the paper. To see explicitly how this third measurement works, represent the state of the comparison apparatus by Mc[(…)1(…)2], where the first entry measures the record of the apparatus measuring the first particle, and the second entry measures the record of the apparatus measuring the second particle. However, the most probable value of the relative frequency has been shown (ref. 51–52, and ref. widely: Quantum nonlocality exists and may be proved using counterfactuals; quantum nonlo-cality exists but the counterfactual proof is untenable; quantum nonlocality does not exist. The sum in the second line of [21] has been evaluated by differentiating the generating function of the binomial series ∑r=0NCrNprqN−r=(p+q)N. That is, we have 〈rm〉 = (p[d/dp])m(p + q)N, where q is regarded as a constant in the differentiation, setting p + q = 1 at the end. If something can hit you, it exists. Quantum nonlocality may be an artifact of the assumption that observers obey the laws of classical mechanics, while observed systems obey quantum mechanics. By comparing a triple set of directions (n^1,n^2,n^3), Bell derived an inequality showing that the hidden variable [27] was inconsistent with quantum mechanical [9]. It is argued that the Heisenberg picture of standard quantum mechanics does not save Einstein locality as claimed in Deutsch and Hayden (Proc. [14]The new function R satisfies the continuity equation∂R2∂t+∑i=1k∇→i⋅(R2∇→iSmi)=0. Image credit: Aurora Fernández Durán (photographer). These are seen to be the relative numbers of distinguishable universes in these states. In that case, the CHSH parameter can be shown to be bounded by The result is completely determined by linearity and the assumed correct measurements on single electrons in eigenstates. I show that quantum nonlocality is an artifact of the assumption that observers obey the laws of classical mechanics, whereas observed systems obey quantum mechanics. 3–5. Locality is restored if observed and observer both obey quantum mechanics, as in the many-worlds interpretation (MWI). In the United States, mortality rates and life expectancy were worse for Blacks during nonpandemic years than for Whites during the COVID-19 pandemic, a study finds. This must be the case, because any direction could have been chosen before a choice is made. So an observation of the approach of the frequencies to the probabilities is actually an observation of the effect of the simultaneous action in the multiverse of the analogs of the human observer. However, at each event of observation, both of the two possible outcomes of the measurement will be obtained. The author declares no conflict of interest. The total number of what I term “effectively distinguishable” universes is the space integral of R2, and this integral may be infinite. That is, if each particle happens to be in an eigenstate of spin, a measurement of the ith particle changes the measuring device—but not the spin of the particle—asU1M1(…)|↑〉1=M1(↑)|↑〉1U1M1(…)|↓〉1=M1(↓)|↓〉1[3]U2M2(…)|↑〉2=M2(↑)|↑〉2U2M2(…)|↓〉2=M2(↓)|↓〉2,[4]where Ui are linear operators that generate the change of state in the measurement apparatus, corresponding to the measurement. The most general expression of classical mechanics is the Hamilton–Jacobi equation∂S∂t+H(xi,∂S∂xi,t)=0. However, the other worlds of the multiverse really do exist even in classical mechanics: It is the collision of the worlds that yields the caustics. The ellipsis denotes a measurement not yet having been performed. Note that I have placed the word probabilities above in quotation marks. Surely, Albert Einstein once complained, the Moon does not exist only when we look at it! Changing environmental conditions and genetic adaptations may explain how penguins radiated and expanded their geographic ranges to encompass diverse environments. I show that these most likely frequencies are the Born frequencies. been confirmed by every experiment to date), then nonlocality does not exist, since the speed of light is the fastest anything can travel, and therefore the multiverse of the Many-Worlds Interpretation logically must exist (i.e., due to the reason given in Prof. Tipler's above paper: that experiments of quantum entanglement actually involve The only reason this seems implausible is due to the neglect of the other universes—other observers—in the multiverse. Once again, it is easily seen that initialization of this third measurement by the two previous measurements, plus linearity, implies that this third measurement will confirm the split into two worlds. It's an intriguing new hypothesis that has started to garner attention as researchers continue to debate the merits of multiple models. Quantum nonlocality is shown to be an artifact of the Copenhagen interpretation, in which each observed quantity has exactly one value at any instant. Lond. My derivation starts from the standard MWI idea that the wave function is not a probability amplitude, but instead a “world density amplitude,” which is to say |ψ|2 is proportional to the density of universes in the multiverse. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Quantum nonlocality is shown to be an artifact of the Copenhagen Interpretation, which assumes that observers obey the laws of classical mechanics, while observed systems obey quantum mechanics. Because there is no difference between the initial states of the observers, there is no difference in the terms of the expression except for the labels I have given them, and the labels can be interchanged, leaving the physics invariant. The first term in the second line of [18] will equal one if Sk records exactly r measurements of the spin in the θ direction and will be zero otherwise. In the case of quantum mechanics, the ignorance in question is ignorance of the other universes of the multiverse. We do not capture any email address. The second electron’s spin is given by an analogous function B(n^2,λ2), and so the hidden variable expectation value for the product of the spins would not be [13] but instead∫ρ(λ1,λ2)A(n^1,λ1)B(n^2,λ2)dλ1 dλ2,[27]where ρ(λ1, λ2) is the joint probability distribution for the hidden variables. With impressive specificity, RNAi can potentially block nucleotide sequences that are only found in a target pest and not in friendly insects or humans. A 456, 1759-1774, 2000). Nonlocality is a word used by scientists about time in quantum physics. At the quantum level, reality does not exist if you are not looking at it," lead researcher and physicist Andrew Truscott said in a press release. 3, p. 149) that nonlocality would disappear in the MWI, but this paper is to my knowledge the first to prove what Everett claimed. 16 and 17 for a detailed discussion of this point). Using the MWI, I show that the quantum side of Bell’s inequality is entirely local. There is no mystery. Brian D ... in principle effective use by organisms of the direct interconnections between spatially separated objects shown to exist in the work of J.S. Source: Proceedings of the National Academy of Sciences of the United States of America 2014 v.111 no.31 pp. I see it every day, when I see the earth’s rotation expose the unmoving sun at dawn and cover the unmoving Sun from my view at dusk. This separation requires the third measurement, and this local comparison measurement retains the correlations between the spins. For simplicity I assume that the spins of a series of electrons are measured and that the spins of all of the measured electrons are spin up before the measurement. This is not the meaning given to probability by the physicist founder of probability theory, Pierre-Simon de Laplace, for whom probabilities are a numerical measure of human ignorance and not an objective feature of nature (10). The operators Ui are actually unitary, but this is not essential to the argument. The Hamilton–Jacobi equation has been recognized since the 19th century as the most powerful mathematical expression of classical mechanics. 11, p. 241). If we decide to measure the particle spins in the left–right direction, the wave function would be written in a left–right basis as|Ψ〉=|←〉1|→〉2−|→〉1|←〉22.[2]. These statements are true because quantum mechanics tells us that the wave function does not collapse when the state of a system is measured.

State transitions are entirely local in quantum mechanics. In order for something to exist as an individual material object, it must occupy a certain volume of space at a certain time. We think that one thing cannot be several places at once, but scientists have agreed that an elementary particle – … The way the measurement of [9] is actually carried out in the Aspect–Clauser–Freedman experiment is to let θ be random in any single run and for the results of each fixed θ from a series of runs be placed in separate bins. Heretofore I have assumed that the two observers have chosen to measure the spins in the same direction. Because the N electrons are independent, the probability of getting any particular sequence Sk depends only on the number of electrons with spins measured to be in the θ direction and on the number with spins measured in the opposite direction. The automatic elimination of action at a distance by the MWI is a powerful argument for the validity of the MWI. Then for the state [1], the totality of the three measurements together—the two measurements of the particle spins followed by the comparison measurement—isUcU2U1Mc[(…)1(…)2]M2(…)M1(…)××[|↑〉1|↓〉2−|↓〉1|↑〉22]=Mc[(↑)1(↓)2]M2(↓)M1(↑)|↑〉1|↓〉22−− Mc[(↓)1(↑)2]M2(↑)M1(↓)|↓〉1|↑〉22. The effect of throwing away this correlation information would be equivalent to averaging over all θ in the computation of the expectation value: The result is ∫0π〈Ψ|(n^1⋅σ1)(n^2⋅σ2)|Ψ〉dθ=0; i.e., the measured spin orientations of the two electrons are completely uncorrelated. To show how [9] comes about by local measurements splitting the universe into distinct worlds, I follow [9] and write the singlet state [1]/[2] with respect to some basis in the n^1 direction as|Ψ〉=(1/2)(|n^1,↑〉1|n^1,↓〉2−|n^1,↓〉1|n^1,↑〉2). Today some physicists suspect that, whether or not consciousness influences quantum … 1 and 2: All possible pairs exist. The Phenomenon of Quantum Nonlocality. Edited* by John P. Perdew, Temple University, Philadelphia, PA, and approved June 2, 2014 (received for review December 30, 2013). Using the MWI, I show that the quantum side of Bell’s inequality, generally believed nonlocal, is really due to a series of three measurements (not two as in the standard, oversimplified analysis), all three of which have only local effects. 1–8. The operator ∇→i is, for each i, the differential operator in 3li dimensions. DOI: 10.1073/pnas.1324238111 Corpus ID: 953508. Consider the CHSH Bell scenario detailed before, but this time assume that, in their experiments, Alice and Bob are preparing and measuring quantum systems. This view allows the Born interpretation to be derived directly from the Schrödinger equation, by applying the Schrödinger equation to both the observed and the observer. Using the MWI, I show that the quantum side of Bell’s inequality is entirely local. (1), in their classic paper, “Can quantum mechanical description of physical reality be considered complete?”, The basic idea in Einstein, et al.’s paper (1) is best described in the well-known formulation in terms of two electrons and their spins. Our opinion is the second one, so that an existence proof of quantum nonlocality should be based on actual events. From the MWI viewpoint, humans and their equipment are quantum mechanical objects no less than atoms and are thus subject to indistinguishability no less than atoms. There is no quantum nonlocality. We see that Schrödinger’s equation does not require the integral of R2 to be finite, and there will be many cases of physical interest in which it is not. I thank B. S. DeWitt, D. E. Deutsch, J. P. Perdew, and H. Stapp for helpful discussions. It's an intriguing new hypothesis that has started to garner attention as researchers continue to debate the merits of multiple models. A huge number of papers are published each year in the major physics journals [e.g., 5 in Physical Review Letters (PRL) in 1997 and 23 in PRL in … A huge number of papers are published each year in the major physics journals [e.g., 5 in Physical Review Letters (PRL) in 1997 and 23 in PRL in 2004], … Image credit: Anang Dianto (photographer). If many universes exist—as they do—then there must be a quantity representing a density of universes. The problem is to derive the Born frequencies from this assumption. To see this, let me show that quantum mechanics is just classical mechanics required to be globally deterministic. Most think that probability means the relative frequency of some event among some collection of events, for example the relative number of times we measure the spin to be up, divided by the total number of times we measure the spin in the vertical direction, in the limit as the number of measurements approaches infinity. It has prevented physicists from realizing that they are actually observing the effects in our universe of the other universes of the multiverse. Assuming the wave function is a world density amplitude, I derive the Born interpretation directly from Schrödinger’s equation. We do not capture any email address. There should exist a reformulation of quantum theory which does not refer to classical time. It is, instead, that the quantum property of indistinguishability, applied to the observers, forces the measured frequencies to approach the probabilities. Author contributions: F.J.T. This view allows the Born interpretation to be derived directly from the Schrödinger equation, by applying the Schrödinger equation to both the observed and the observer. The Aspect–Clauser–Freedman experiment (7, 8) is designed to use more of the data by testing Bell’s inequality for the expectation value of the product of the spins of the two electrons with the spin of one electron being measured in direction n^1 and the spin of the other in direction n^2. Nonlocality is a standard example of a quantum mechanical property not present in classical mechanics. There is no quantum nonlocality. It cannot be emphasized too strongly that a probability cannot be an objective feature of reality, but instead a probability is a numerical expression of human ignorance of the actual state of affairs. Biological Utilisation of Quantum NonLocality. NOTE: We only request your email address so that the person you are recommending the page to knows that you wanted them to see it, and that it is not junk mail. In the case of spin up and spin down, there are only two possible universes, and so the general rule for densities requires us to have the squares of the coefficients of the two spin states be the total number of effectively distinguishable—in this case obviously distinguishable—states. 17 is linear, it cannot give rise to caustics and hence is globally C2. A.V. This quantum property of indistinguishability also allows us to answer the question, “What were the two electron spins before a choice of the measurement directions was made?” The answer is given by the formalism, as indicated in Eqs. The experiment could be carried out by throwing away all observations except those in which the chosen directions happened to agree within a predetermined tolerance. Belinsky, A.A. Klevtsov “Nonlocal classical "realism" and quantum superposition as the nonexistence of definite pre-measurement values of physical quantities” 61 313–319 (2018) 03.65.Ud , 42.65.Lm ( all ) Previous derivations have been unsatisfactory, in my judgment, because an essential part of the physics has been left out. But in a 1935 paper, Einstein and his co-authors showed how entanglement leads to what's now called quantum nonlocality, the eerie link that appears to exist between entangled particles. an effect exceeding the speed of light). Bell’s analysis tacitly assumes that the macroscopic world is a single-valued world. However, the course of atoms and their spins in the multiverse is exactly and completely determined by the deterministic wave equation. There should exist a reformulation of quantum theory which does not refer to classical time. If it does not, then whatever it is – if it’s anything at all – it’s not a material object. Locality is restored if observed and observer are both assumed to obey quantum mechanics, as in the many-worlds interpretation (MWI). Similarly, the result of measuring the ith particle in the eigenstate of spin left would be UiMi(…)|←〉i = Mi(←)|←〉i and for an eigenstate of spin right would be UiMi(…)|→〉i = Mi(→)|→〉i, which will generate equations for spins left and right analogous to Eqs. This state is [1] or [2] with respect to an up/down or left/right basis, respectively. [19], However, the order in which the r aligned spins and the N − r antialigned spins are obtained is irrelevant, so the number of times [19] appears in the sum [18] will be CrN, the number of combinations. I show that, at least in the case of Bell's Theorem, locality is restored if observed and observer are both assumed to obey quantum mechanics, as in the Many-Worlds Interpretation. Author contributions: F.J.T. Everyone believed this was so until Copernicus and Galileo taught us to see nature through the laws of physics. With impressive specificity, RNAi can potentially block nucleotide sequences that are only found in a target pest and not in friendly insects or humans. With this normalization, R2d3X is then the ratio of the number of effectively distinguishable universes in the region d3x to the total number of universes. Nonlocality is a standard example of a quantum mechanical property not present in classical mechanics. In Laplacean probability theory, the relative frequency is a parameter to be estimated from a probability, not a probability itself (see refs. Because the singlet state is rotationally invariant, the same result would be obtained whatever direction the observers happened to choose to measure the spins. We propose a resolution for this discord by first observing that there is a problem of time in quantum theory. In this case the Laplacean probabilities for measuring spin up along the axis of the apparatus are p↑,θ = cos2(θ/2) ≡ p and for measuring spin as antialigned with the axis are p↓,θ = sin2(θ/2) ≡ q, respectively, for 0 ≤ θ ≤ π/2. Now let us use the MWI and Laplacean probability theory to analyze the Bell experiment. For example, the effect of measurements in which both observers happen to choose to measure with respect to the up/down basis isU2U1M2(…)M1(…)[|↑〉1|↓〉2−|↓〉1|↑〉22]=U2M2(…)[M1(↑)|↑〉1|↓〉22−M1(↓)|↓〉1|↑〉22]=M2(↓)M1(↑)|↑〉1|↓〉22−M2(↑)M1(↓)|↓〉1|↑〉22.[6]. ↵*This Direct Submission article had a prearranged editor. Quantum indistinguishability and our ignorance of the other universes preclude an increase in knowledge. State transitions are nice and local in quantum mechanics. Image credit: Science Source/USDA/Nature Source. The language of the frequency interpretation of probability has prevented physicists from seeing what is actually happening. Because Eq. Thus, the third measurement acting on eigenstates of the spin-measurement devices transforms the comparison apparatus asUcMc[(…)1(…)2]M1(↑)=Mc[(↑)1(…)2]M1(↑)UcMc[(…)1(…)2]M1(↓)=Mc[(↓)1(…)2]M1(↓)UcMc[(…)1(…)2]M2(↑)=Mc[(…)1(↑)2]M2(↑)UcMc[(…)1(…)2]M2(↓)=Mc[(…)1(↓)2]M2(↓),where for simplicity I have assumed the spins will be measured in the up or down direction. In particular, because the only sequences that contribute to [18] are those with r spins measured to be in the θ direction and those with N − r spins to be in the opposite direction, we haveprob(Sk | N)=prqN−r. Inserting these probabilities—the squares of the coefficients in [11]—into [25] gives the expectation value12sin2⁡θ/2−12cos2⁡θ/2−12cos2⁡θ/2+12sin2⁡θ/2=−cos⁡θ=−n^1⋅n^2,[26]which is the quantum expectation value, [9]. [12]The most general Hamiltonian we need to consider isH=∑i=1k(∇→iS)22mi+V(x1,x2,…,x3N,t),[13]where there are k particle types, each type with mass mi, and each particle type has li particles. The effect of measurements in which both observers happen to choose to measure with respect to the left/right basis isU2U1M2(…)M1(…)[|←〉1|→〉2−|→〉1|←〉22]=U2M2[M1(←)|←〉1|→〉22−M1(→)|→〉1|←〉22]=M2(→)M1(←)|←〉1|→〉22−M2(←)M1(→)|→〉1|←〉22.[8]. The function R2 is this natural choice for this density. Thank you for your interest in spreading the word on PNAS. Genetic insights could help shore up populations of a rare dog species thought to be nearly extinct in the wild. Quantum nonlocal correlations and the acausal, spooky action at a distance suggest a discord between quantum theory and special relativity. In reality, all physical systems obey quantum mechanics, which obeys no such rule. Using the MWI, I show that the quantum side of Bell’s inequality is entirely local. 17 is obviously just the Schrödinger equation. Everett was the first to suggest (ref. [22]In fact, all moments of the difference between f and p vanish as N → ∞, because the generating function gives〈(rN−p)m〉∼1N+higher order terms in 1N.[23]. 6 that it is the first measurement to be carried out that determines the split into the two worlds represented by two terms in [6].
