Macroscopically Nonlocal Quantum Correlations

نویسندگان

چکیده

It is usually believed that coarse-graining of quantum correlations leads to classical in the macroscopic limit. Such a principle, known as locality, has been proved for arising from independent and identically distributed (IID) entangled pairs. In this letter we consider generic (non-IID) scenario. We find Hilbert space structure theory can be preserved This directly Bell violation coarse-grained collective measurements, thus breaking principle locality.

Jamming nonlocal quantum correlations.

We present a possible scheme to tamper with non-local quantum correlations in a way that is consistent with relativistic causality, but goes beyond quantum mechanics. A non-local “jamming” mechanism, operating within a certain space-time window, would not violate relativistic causality and would not lead to contradictory causal loops. The results presented in this Letter do not depend on any mo...

Quantum Correlations in Nonlocal BosonSampling

Determination of the quantum nature of correlations between two spatially separated systems plays a crucial role in quantum information science. Of particular interest is the questions of if and how these correlations enable quantum information protocols to be more powerful. Here, we report on a distributed quantum computation protocol in which the input and output quantum states are considered...

Monogamy of nonlocal quantum correlations

We describe a new technique for obtaining Tsirelson bounds, or upper bounds on the quantum value of a Bell inequality. Since quantum correlations do not allow signaling, we obtain a Tsirelson bound by maximizing over all no-signaling probability distributions. This maximization can be cast as a linear program. In a setting where three parties, A, B, and C, share an entangled quantum state of ar...

On the plasticity of nonlocal quantum correlations

Karl Svozil∗ Institute for Theoretical Physics, Vienna University of Technology, Wiedner Hauptstraße 8-10/136, A-1040 Vienna, Austria Abstract The quantum correlations of two or more entangled particles present the possibility of strongerthan-classical outcome coincidences. We investigate two-partite correlations of spin one, three-half and higher quanta in a state satisfying a uniqueness prope...

Multipartite Nonlocal Quantum Correlations Resistant to Imperfections

We use techniques for lower bounds on communication to derive necessary conditions in terms of detector efficiency or amount of super-luminal communication for being able to reproduce with classical local hidden-variable theories the quantum correlations occurring in EPR-type experiments in the presence of noise. We apply our method to an example involving n parties sharing a GHZ-type state on ...
