Experiments
2012: Empty waves, many worlds, parallel lives, and nonlocal decision at detection
Antoine Suarez
arXiv:1204.1732 [quant-ph]
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.

2012: Single-photon space-like antibunching
Thiago Guerreiro, Bruno Sanguinetti, Hugo Zbinden, Nicolas Gisin, and Antoine Suarez
Physics Letters A 376 (2012) 2174–2177 arXiv:1204.1712 [quant-ph]
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.
Antoine Suarez
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
Antoine Suarez
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.

2003: Quantum entanglement with acousto-optic modulators:
Two-photon beats and Bell experiments with moving beam splitters.
André Stefanov, Hugo Zbinden, Nicolas Gisin and Antoine Suarez.
Physical Review. A, volume 67, 042115.
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.
N. Gisin, V. Scarani, A. Stefanov, A. Suarez, W. Tittel and H.
Zbinden
Optics & Photonics News, December 2002, 51.
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.

2002:
Quantum Correlations with Spacelike Separated Beam Splitters in
Motion: Experimental Test of Multisimultaneity.
André Stefanov, Hugo Zbinden, and Nicolas Gisin -
Antoine Suarez.
Physical Review Letters volume 88, number 12.
Article about the experiment using acoustic waves as moving
beam-splitters.
Multisimultaneity is a causal model of relativistic quantum physics
which assigns a real time ordering to any set of events, much in the
spirit of the pilot-wave picture. Contrary to standard quantum
mechanics, it predicts a disappearance of the correlations in a
Bell-type experiment when both analyzers are in relative motion such
that each one, in its own inertial reference frame, is first to select
the output of the photons. We tested this prediction using acousto-optic
modulators as moving beam splitters and interferometers separated by
55 m. We did not observe any disappearance of the correlations, in
agreement with quantum mechanics.

2001:
Is there a time ordering behind nonlocal correlations?
Antoine Suarez.
quant-ph/0110124.
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.
H. Zbinden, J.
Brendel, N. Gisin, and W. Tittel.
Phys. Rev.
A, 63.022111.
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.
Antoine Suarez.
Phys. Lett.
A, 269, 293-302.
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?
A. Suarez and V.
Scarani
Phys.Lett.
A, 232, 9-14 390 (www.elsevier.nl),
and quant-ph/9704038.
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.

Etienne Klein comments the results of the Geneva experience testing
Multisimultaneity and concludes that the quantum correlation is caused
without any flow of time but, once produced, it becomes engraved in time.

Magazine article on the experiments with moving apparatuses stressing that
in the realm of the nonlocal quantum phenomena things come to pass but the
time doesn't seem to pass here. The article points out also the relevance of
quantum entanglement for practical applications as cryptography.
