Abstract

This is a statistical analysis of the experimental data used in a recent paper [Lynden K. Shalm et al, Phys. Rev. Lett. 115, 250402 - Published 16 December 2015 at http://journals.aps.org/prl/abstract/10.1103/PhysRevLett.115.250402. The data for this analysis has been made available by the authors at http://pml.nist.gov/belldata/belldata+processed_compressed+hdf5.html in hdf5 format. This article is not meant in any way to comment upon the originally published findings of the experiment. Abstract – Till date, all experiments prove non-locality of entanglement based upon overall statistical correlations and thus demonstrating that Bell’s inequality is violated. No detailed data analysis has been published yet. This article presents detailed data analysis of its kind and it indicates that there is a real chance that non-local entanglement may not exist. This is a huge claim by any means. But it is necessary to make such dramatic claim due to two reasons – 1) It is based upon experimental data and can be tested and verified. 2) So that the QM community makes an effort to analyze detailed data to scrutinize the locality of entanglement. This is second experiment that gives such an indication. The first of this kind data analysis was conducted on another recent experiment data and the observation is posted at http://vixra.org/abs/1609.0237. Due to large amount of data involved, experimentalists only analyze data at aggregate level and do not scrutinize the raw data in full detail. When data of this experiment was analyzed at detail level, it was observed that non-locality of entanglement can not be settled until this kind of analysis is completed on data from multiple such experiments. The natural and prompt reaction from many may be to look for faults with this analysis without presenting the evidence that such analysis has already been completed. For curious people, observation is odd enough to be probed further. The complacent ones will look only for the faults, but those who welcome scrutiny, will challenge it with evidence and/or their own analysis at this detailed level. All sound theories welcome scrutiny and refute it with evidence. This article does not claim “classical mechanics” to be the solution. Quantum Mechanics predictions are correct in terms of averages. This analysis indicates that the statistical correlation percent of entanglement may be guided/balanced by some real/local mechanism rather than being independently probabilistic and spooky. It presents an intuitive mechanism that can explain statistical correlations without entanglement being non-local or entanglement being defined in a different way then it currently is. The scope of this article is only statistical data. Anti correlation (Bell’s state, when measured in the same angle) is always true, therefore it is not statistical in nature and is left out of scope. Moreover perfect anti correlation can easily be explained as a direct consequence of conservation laws. In fact, perfect anti correlation is a big red flag to the probabilistic nature. There is no such thing as zero, or one probability. Zero or one probability would actually be a law, not probability. So, perfect anti correlation itself indicates that the outcomes of entanglement can not be probabilistic, they have to be governed by law, not probability. If some balancing mechanism is found to exist then (in terms of magnitude), it really operates within probabilistic limits thereby making it very difficult to differentiate it from probabilistic nature. Therefore a detailed data analysis on many such experiments is necessary to rule it in/out. In fact it would require special experiments for its independent investigation. This can also explain why the correlations have been considered probabilistic for such a long history. Therefore, this type of experimental investigation is a must in order to conclude existence/nonexistence of non-local entanglement.

Quantum Entanglement Experiment Data Indicates Balancing Mechanism

Krishan Vats

This article presents analysis of experimental data. The data was acquired from a recently published experiment, the link to the published paper is https://arxiv.org/abs/1511.03190. The data analysis gives an indication that the outcomes may not be totally probabilistic and may be guided by some other mechanism. This article only presents an independent observation and is not meant in any way to comment on the originally published findings of the referred experiment from which the data was acquired. This article also does not dispute any quantum mechanics quantitative predictions. It only presents the observation made so that more experiments/analysis may be conducted if deemed necessary. As such, the observation pointed out is minor and its magnitude can be attributed to independent probability. But the same “cumulated imbalance” direction and trend in all four setup combinations is something that would be hard to attribute to probability alone. Also, the accumulated imbalance cleared for all four setups exactly at the same time. The scope of this article is only statistical data. Anti correlation (when measured in the same angle) is always true, therefore it is not statistical in nature and is left out of scope.

Non-Locality and Quantum Theory: New Experimental Evidence

Luigi Accardi, Massimo Regoli

Starting from the late 60’s many experiments have been performed to verify the violation Bell’s inequality by Einstein-Podolsky-Rosen (EPR) type correlations. The idea of these experiments being that: (i) Bell’s inequality is a consequence of locality, hence its experimental violation is an indication of non locality; (ii) this violation is a typical quantum phenomenon because any classical system making local choices (either deterministic or random) will produce correlations satisfying this inequality. Both statements (i) and (ii) have been criticized by quantum probability on theoretical grounds (not discussed in the present paper) and the experiment discussed below has been devised to support these theoretical arguments. We emphasize that the goal of our experiment is not to reproduce classically the EPR correlations but to prove that there exist perfectly local classical dynamical systems violating Bell’s inequality. The conclusions of the present experiment are: no contradiction between quantum theory and locality can be deduced from the violation of Bell’s inequality. The Copenhagen interpretation of quantum theory becomes quite reasonable and not metaphyisic if interpreted at the light of the chameleon effect. One can realize quantum entanglement by classical computers. In section (7) we prove that our experiment also provides a classical analogue of the type of logical (i.e. independent of statistics) incompatibilities pointed out by Greenberger, Home and Zeilinger. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

A Scrutiny of Landmark Experiments Disproves Photonic Quantum Nonlocality

Andre Vatarescu

A physical scrutiny of experimental results published in Physical Review Letters (December 2015, M. Giustina, et al., Phys. Rev. Lett. 115, 250401, and L. K. Shalm et al., Phys. Rev. Lett. 115, 250402) is undertaken. These articles reported that measured outcomes were fitted with quantum states possessing a dominant component of non-entangled photons, thereby contradicting their own claim of quantum nonlocality. With probabilities of photon detections lower than 0.1 %, the alleged quantum nonlocality cannot be classified as a resource for developing quantum computing devices, despite recent publicity. Experimental evidence of a feasible process for quantum-strong correlations has been identified (M. Iannuzzi, et al., Phys. Lett. A, 384 (9), 126200, 2020) in terms of correlations between independent and multi-photon states evaluated as Stokes vectors on the Poincaré sphere. As single-photon sources are not needed, the design and implementation of quantum computing operations will be significantly streamlined.

Testing EPR

Jonathan A. Jones, Dieter Jaksch

Quantum physics violates the basic assumptions of local realism. Particles can be entangled with each other in ways that allow correlations stronger than possible in classical physics. This was first realized by Einstein, Podolsky and Rosen (EPR) in 1935 and led them to conclude that quantum theory was incomplete. It took about 30 years before J. S. Bell found observable consequences of this phenomenon by showing how entangled states violate inequalities for two-particle correlations derived purely from the assumption that the world obeys local realism. Violations of Bell inequalities were first observed experimentally in the Aspect experiment, which will be discussed below. Such experiments are technically challenging and care is needed to avoid any loopholes in the experimental setup that would still permit the description of the experiments by a local realistic theory. Bell inequalities describe violations of local realism on average, meaning that each individual experimental outcome could occur in a local realistic theory. It is the statistics of these outcomes that violates local realism. In contrast, another class of quantum states, so-called Greenberger–Horne–Zeilinger (GHZ) states, which contain three particles, can be shown to violate local realism in each measurement outcome. We will also discuss this class of states and experiments by Zeilinger's group, which demonstrated this type of violation of local realism for the first time. Our aim here is not to discuss the exact relations between quantum entanglement, non-locality and realism, and their physical and philosophical implications. While this is a highly interesting topic which attracts a lot of attention from researchers, such an exploration would go beyond the scope of this book.
