the fact that Alice and Bob should be spacelike separated so that the choice of measurements cannot influence one another, was first closed after the ’80s [318,319]. On the other hand, the detection loophole [320,321], which is related to the inefficiencies of detectors, was closed in ...
The statistical error in any estimation can be reduced by repeating the measurement and averaging the results. The central limit theorem implies that the reduction is proportional to the square root of the number of repetitions. Quantum metrology is the
We examine two noise models—one at the sources and one at the detectors. First we introduce a visibility to the singlets such that all three shared quantum states have the form (5). Second, we examine detector noise, in which each detector defaults independently with probability 1 −...
The proposed experiment tests a particular approach to holography, but should not be seen as a general test of holography, especially more mainstream formulations based on AdS/CFT. A positive result (the detection of new physics in the experiment) should be considered strong indication that the ho...
Network nonlocality means that it does not admit a network model involving local variables emitted from independent sources. In this work, we construct an (n, m, p)-type quantum network configuration and then derive the corresponding n-local correlation inequalities based on the assumption of ...
Then magically the wave-like nature transmutes into a particle-like nature because the detectors do not register a wave but just the impact of a particle. In contrast, in SQM the particle is a wave-like corpuscle—meaning that it is equipped with some wave-like behaviour—which bears little...
Quantum correlations for particle detectors and the dynamical Casimir effects on these correlations are also provided here. Finally, in Section 9, we present a concluding remark on the main results of this review. We hope the review be helpful for further exploration in these fields. Several ...
A quantum cache includes a quantum store having an input that receives a quantum state having fundamental quantum properties comprising coherence and is configured to store the quan
Figure 2. Alice and Bob making spin measurements in the xz plane on a pair of spin-entangled particles with their Stern-Gerlach (SG) magnets and detectors. Bob observes the same regarding his SG magnet orientationβ. Thus, the source is rotationally invariant in the spatial plane P orthogonal...
Weak limit (g→ 0): The system fails to couple to the detectors. The bound (26) reduces to minw2{−log(pj1Vpj2VTr(Πw2W))}. The probability distribution {pjℓV} has a spread quantified by the Shannon entropy HSh({pjℓV}). The left-hand side of Eq. (24) reduces to 2[...
