2012: Empty waves, many worlds, parallel lives, and nonlocal decision at detection

The “Single-photon space-like antibunching” experiment demonstrates that conservation of energy in each single event implies nonlocal coordination of detections: the most fundamental principle ruling the material visible world emerges from non-material invisible principles.

The experiment (proposed 2010 by A. Suarez and completed 2012 by the group of N. Gisin) uses heralded single photons to perform an antibunching experiment in which the clicks at the detectors are spacelike separated events. The idea of such experiment dates back to the 5th Solvay conference, when it was proposed by Einstein as an expression of his concerns about quantum theory.

2008: Quantum randomness can be controlled by free will -a consequence of the before-before experiment.

arXiv: 0804.0871v1 [quant-ph]

The before-before experiment demonstrates that quantum randomness can be controlled by influences from outside spacetime, and therefore by immaterial free will. Rather than looking at quantum physics as the model for explaining free will, one should look at free will as a primitive principle for explaining why the laws of Nature are quantum.

2008: Nonlocal "Realistic" Leggett Models Can be Considered Refuted by the Before-Before Experiment

Found Phys (2008) 38: 583-589 DOI 10.1007/s10701-008-9228-y

Nonlocal "realistic" Leggett models can be considered refuted by the before-before experiment. "Single preferred frame" models are not refuted by this experiment but bear severe oddities.

2007: Classical Demons and Quantum Angels: On 't Hooft's deterministic Quantum Mechanics

Antoine Suarez

arXiv:0705.3974v1 [quant-ph]

The article discusses the free will assumption in quantum mechanics, and proposes the quantum homeostasis hypothesis for explaining consciousness and sleep.

It is argued that 't Hooft's deterministic program does not disenchant the quantum world but rather inspires the incantation of the classical one.

2003: Entanglement and Time

Antoine Suarez

quant-ph/0311004

Article about the implications of the experiments with moving measuring devices.

It is argued that recent experiments testing Multisimultaneity prove that quantum entanglement occurs without the flow of time. Bohm's theory cannot be considered a real temporal description.

Full-length article about the experiment using acoustic waves as moving beam-splitters.
We present an experiment testing quantum correlations with frequency shifted photons. We test Bell inequality with two-photon interferometry where we replace the beam splitters with acousto-optic modulators, which are equivalent to moving beam splitters. We measure the two-photon beats induced by the frequency shifts, and we propose a cryptographic scheme in relation. Finally, setting the experiment in a relativistic configuration, we demonstrate that the quantum correlations are not only independent of the distance but also of the time ordering between the two single-photon measurements.

2002: Quantum Correlations With Moving Observers.

Short presentation of the experiments with moving devices.
 

The experiments with moving measuring devices can be considered a fundamental test of quantum mechanics and information. The December issue of Optics and Photonics News highlighted some of the most exciting research to emerge in during 2002. The GAP-Optics experiments studying the quantum correlations with moving observers was a first for a new kind of experiment to test quantum non-locality.

2001: Is there a time ordering behind nonlocal correlations?

Article discussing the results of the experiments with moving beam-splitters.

It is argued that recent experiments with moving beam-splitters demonstrate that there is no real time ordering behind the nonlocal correlations. In Bell's world there is no "before" and "after".

2001: Experimental test of nonlocal quantum correlations in relativistic configurations.

Article describing the before-before experiment using a detector in motion.

We report on an experimental investigation of the tension between quantum nonlocality and relativity. Entangled photons are sent via an optical fiber network to two villages near Geneva, separated by more than 10 km where they are analyzed by interferometers. The photon pair source is set as precisely as possible in the center so that the two photons arrive at the detectors within a time interval of less than 5 ps (corresponding to a path length difference of less than 1 mm). One detector is set in motion so that both detectors, each in its own inertial reference frame, are first to do the measurement! The data always reproduces the quantum correlations, making it thus more difficult to consider the projection postulate as a compact description of real collapses of the wave function.

2000: Quantum mechanics versus multisimultaneity in experiments with acousto-optic choice-devices.

Article proposing "before-before" and "after-after" experiments using acoustic waves as moving beam-splitters.

It is argued that acousto-optic cells act as moving beam-splitters because the velocity corresponding to the Doppler-shift of the reflected photons defines a natural frame in which it is possible to evaluate unambiguously whether the choice between reflection and transmission is before or after. New experimental tests of Multisimultaneity are discussed.

1997: Does entanglement depend on the timing of the impacts at the beam-splitters?

First article to propose experiments using measuring devices in motion and the relativistic “before-before” timing.

A new nonlocality experiment with moving beam-splitters is proposed. The experiment is analyzed according to conventional quantum mechanics, and to an alternative nonlocal description (Multisimultaneity) in which superposition depends not only on indistinguishability but also on the timing of the impacts at the beam-splitters.
