We report on a new kind of experimental investigations of the tension between quantum nonlocally 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…

Experimental test of relativistic quantum state collapse with moving reference frames

An experimental test of relativistic wave-packet collapse is presented. The tested model assumes that the collapse takes place in the reference frame determined by the massive measuring detectors.

Quantum correlations with spacelike separated beam splitters in motion: experimental test of multisimultaneity.

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, which predicts a disappearance of the correlations in a Bell-type experiment when both analyzers are in relative motion.

Quantum correlation with moving beamsplitters in relativistic configuration

We present a recent experiment [1] using space-like beamsplitters in motion revealing a new feature of quantum nonlocality: The correlations caused by two-particle quantum entanglement are not only

The origin of quantum nonlocality

Quantum entanglement is the quintessential characteristic of quantum mechanics and the basis for quantum information processing. When one of two maximally entangled particles is measured, without

Apparent Superluminal Speeds in Evanescent Fields, Quantum Tunnelling and Quantum Entanglement

Three cases of wave propagation involving possible superluminal speeds are discussed. The picture that emerges is that the actual propagation velocity of the wave front never exceeds the speed of

Relativity, entanglement and the physical reality of the photon

Recent experiments on the classic Einstein-Podolsky-Rosen (EPR) setting claim to test the compatibility between nonlocal quantum entanglement and the (special) theory of relativity. Confirmation of

Based on quantum entanglement and corresponding quantum communication, we research a simple superluminal entangled communication scheme, whose key is to establish two mutually entangled particles or

Invariance of Spooky Action at a Distance in Quantum Entanglement under Lorentz Transformation

We study the mechanism by which the particle-antiparticle entangled state collapses instantaneously at a distance. By making two key assumptions, we are able to show not only that instantaneous

Long distance quantum teleportation of qubits from photons at 1300 nm to photons at 1550 nm wavelength

Elementary 2-dimensional quantum states (qubits) encoded in 1.3 µm wavelength photons are teleported onto 1.55 µm photons. The use of telecommunication wavelengths enables to take ad-vantage of

On the uncertainty of the ordering of nonlocal wavefunction collapse when relativity is considered

The temporal measurement order and therefore the originator of the instantaneous collapse of the wavefunction of a spatiality entangled particle pair can change depending on the reference frame of an



Can we make sense out of the measurement process in relativistic quantum mechanics

We study the instantaneity of the state-reduction process in relativistic quantum mechanics. The conclusion of various authors that this instantaneity will restrict the set of relativistic

The quantum theory of measurement

The amazing accuracy in verifying quantum effects experimentally has recently renewed interest in quantum mechanical measurement theory. In this book the authors give within the Hilbert space

Can Quantum-Mechanical Description of Physical Reality Be Considered Complete?

Consideration of the problem of making predictions concerning a system on the basis of measurements made on another system that had previously interacted with it leads to the result that one is led to conclude that the description of reality as given by a wave function is not complete.

Long-distance Bell-type tests using energy-time entangled photons

Quantum Concepts in Space and Time

Recent developments in quantum theory have focused attention on fundamental questions, in particular on whether it might be necessary to modify quantum mechanics to reconcile quantum gravity and

On the Foundations of Quantum Physics

The interpretation of quantum theory has always been a source of difficulties, especially with regard to the theory of measurement. We do not intend to enter here into the details of the polemic

Probably sometime you have said “the wave function of the electron” when you might have said “the wave function of an ensemble of identically prepared electrons” or “the wave function describing my
