Two Faced Janus of Quantum Nonlocality [PDF]

open access: yesEntropy, 2020
This paper is a new step towards understanding why “quantum nonlocality” is a misleading concept. Metaphorically speaking, “quantum nonlocality” is Janus faced. One face is an apparent nonlocality of the Lüders projection and

Strong quantum nonlocality without entanglement in every (n−1)-partition [PDF]

open access: yesiScience
Summary: The orthogonal product set with quantum nonlocality can enhance the confidentiality of information without consuming entanglement resources. The confidentiality increases with the reinforcement of its nonlocality. However, the orthogonal product

Nonlocality activation in a photonic quantum network [PDF]

open access: yesNature Communications
Bell nonlocality refers to correlations between two distant, entangled particles that challenge classical notions of local causality. Beyond its foundational significance, nonlocality is crucial for device-independent technologies like quantum key ...

Nonlocality in quantum cloning states [PDF]

open access: yesScientific Reports
This 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

Genuine hidden nonlocality without entanglement: from the perspective of local discrimination

open access: yesNew 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.

Is the Devil in h?

open access: yesEntropy, 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).
