Non-locality and quantum measurement are two fundamental topics in theory theirinterplay attracts intensive focus since the discovery of Bell theorem. sharing amongmultiple observers is predicted experimentally observed. However, only one-sided sequentialcase, i.e., one Alice multiple Bobs widely discussed little known about two-sided case.Here, we theoretically explore non-locality sequentialm...

It is well known that the fair-sampling loophole in Bell test opened by the selection of the state to be measured can lead to post-quantum correlations. In this paper, we make the selection of the results after measurement, which opens the fair- sampling loophole too, and thus can lead to post-quantum correlations. This kind of result-selection loophole can be realized by pre- and post-selectio...

We present a cognitive psychology experiment where participants were asked to select pairs of spatial directions that they considered to be the best example of Two Different Wind Directions. Data are shown to violate the CHSH version of Bell’s inequality with the same magnitude as in typical Bell-test experiments with entangled spins. Wind directions thus appear to be conceptual entities connec...

A local hidden variable model exploiting the detection loophole to reproduce exactly the quantum correlation of the singlet state is presented. The model is shown to be compatible with both the CHSH and the CH Bell inequalities. Moreover, it bears the same rotational symmetry as spins. The reason why the model can reproduce the quantum correlation without violating the Bell theorem is that in t...

J.S. Bell’s work has convinced many that correlations in violation of CHSH inequalities show that the world itself is non-local, and that there is an apparently essential conflict between any sharp formulation of quantum theory and relativity. Against this consensus, this paper argues that there is no conflict between quantum theory and relativity. Quantum theory itself helps us explain such (o...

A recent sequence of works, initially motivated by the study of the nonlocal properties of entanglement, demonstrate that a source of information-theoretically certified randomness can be constructed based only on two simple assumptions: the prior existence of a short random seed and the ability to ensure that two black-box devices do not communicate (i.e. are nonsignaling). We call protocols a...

We calculate the |Conduction, Heavy Hole (HH)〉 |Split-off Hole (SO), HH〉 (CHSH) Auger Recombination rates for GaAs(1−x)Bix alloys, which are candidates for highly efficient telecommunication devices. A ten-band, tight-binding method, including spin-orbit coupling, was performed on a 9x9x9 strained supercell in order to generate an accurate band structure to perform the calculation on. This band...

Device-independent self-testing allows a verifier to certify that potentially malicious parties hold on to a specific quantum state, based only on the observed correlations. Parallel self-testing has recently been explored, aiming to self-test many copies (i.e. a tensor product) of the target state concurrently. In this work, we show that n EPR pairs can be self-tested in parallel through n cop...

We propose and analyze a protocol for observing violation of the Clauser-Horne-Shimony-Holt (CHSH) Bell inequality using two spatially separated Bose-Einstein condensates (BECs). To prepare correlated state, spin-changing collisions are used to first two-mode squeezed BEC. This is then split into BECs by controlling spatial wave function, e.g., modifying trapping potential. Finally, also exploi...
