Nonlocality in quantum cloning states [PDF]
Scientific ReportsThis study investigates the nonlocality characteristics of output states produced by a universal quantum cloning machine, with particular emphasis on the Bell-CHSH inequality violations exhibited by the two-qubit reduced states of cloned outputs. Through

Macroscopically Nonlocal Quantum Correlations [PDF]
Physical Review Letters, 2021 It is usually believed that coarse-graining of quantum correlations leads to classical correlations in the macroscopic limit. Such a principle, known as macroscopic locality, has been proved for correlations arising from independent and identically distributed (IID) entangled pairs. In this letter we consider the generic (non-IID) scenario.

Genuine hidden nonlocality without entanglement: from the perspective of local discrimination
New Journal of Physics, 2022 Quantum nonlocality without entanglement is a fantastic phenomenon in quantum theory. This kind of quantum nonlocality is based on the task of local discrimination of quantum states. Recently, Bandyopadhyay and Halder (2021 Phys. Rev.

Quantum Nonlocal Aberration Cancellation [PDF]
Physical Review Letters, 2019 Phase distortions, or aberrations, can negatively influence the performance of an optical imaging system. Through the use of position-momentum entangled photons, we nonlocally correct for aberrations in one photon’s optical path by intentionally introducing the complementary aberrations in the optical path of the other photon.

Combinatorics and Quantum Nonlocality [PDF]
Physical Review Letters, 2003 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 the quantum correlations occurring in EPR-type experiments with classical local hidden-variable theories.

Entropy, 2021 This note is a part of my effort to rid quantum mechanics (QM) nonlocality. Quantum nonlocality is a two faced Janus: one face is a genuine quantum mechanical nonlocality (defined by the Lüders’ projection postulate).

Equivalence checking of quantum circuits by nonlocality
npj Quantum Information, 2022 Suppose two quantum circuit chips are located at different places, for which we do not have any prior knowledge, and cannot see the internal structures either.
