Dynamics of nonlocal correlation of two superconducting charge qubits induced by intrinsic decoherence

Alexandria Engineering Journal
The generated nonlocal correlations of two superconducting-charge (SCC) qubits including uncertainty-induced nonlocality (UIN), Bell-Horodecki nonlocality, and negativity’s entanglement have been explored by intrinsic decoherence model.

Connection between Bell nonlocality and Bayesian game theory [PDF]

, 2013
We discuss a connection between Bell nonlocality and Bayesian games. This link offers interesting perspectives for Bayesian games, namely to allow the players to receive advice in the form of nonlocal correlations, for instance using entangled quantum ...

Testing nonlocality in quantum networks using iteratively obtained Bell inequalities [PDF]

, 2018
Quantum networks play an important role in the fields of quantum information and quantum computation. One of the current problems for these networks concerns nonlocality.

Probing Many-Body Bell Correlation Depth with Superconducting Qubits

Physical Review X
Quantum nonlocality describes a stronger form of quantum correlation than that of entanglement. It refutes Einstein’s belief of local realism and is among the most distinctive and enigmatic features of quantum mechanics.

Bell's Inequalities and Density Matrices: Revealing “Hidden” Nonlocality [PDF]

Physical Review Letters, 1995
As is well known, quantum mechanical behavior cannot, in general, be simulated by a local hidden variables model. Most -if not all- the proofs of this incompatibility refer to the correlations which arise when each of two (or more) systems separated in space is subjected to a single ideal measurement.

Residual Bell Nonlocality

, 2020
This report provides a new theoretical measure for the nonlocality of an arbitrary three-qubit pure state system similar to the method used to describe tripartite entanglement, resulting in a concept referred to as residual nonlocality, η. This report also investigates the special cases that can be encountered when using η.

Improved Nonlocality Certification via Bouncing between Bell Operators and Inequalities [PDF]

Bell nonlocality is an intrinsic feature of quantum mechanics, which can be certified via the violation of Bell inequalities. It is therefore a fundamental question to certify Bell nonlocality from experimental data.

Verification of Bell Nonlocality by Violating Quantum Monogamy Relations [PDF]

Quantum nonlocality as a witness of entanglement plays a crucial role in various fields. Existing quantum monogamy relations rule out the possibility of simultaneous violations of any Bell inequalities with partial statistics generated from one Bell ...
