Quantum networks reveal quantum nonlocality [PDF]
Nature Communications, 2010 The results of local measurements on some composite quantum systems cannot be reproduced classically. This impossibility, known as quantum nonlocality, represents a milestone in the foundations of quantum theory.

Experimental Distillation of Quantum Nonlocality [PDF]
Physical Review Letters, 2013 We report the first experimental demonstration of distillation of quantum nonlocality, confirming the recent theoretical protocol [\textit{Phys. Rev. Lett. 102, 120401 (2009)}]. Quantum nonlocality is described by a correlation box with binary inputs and

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.

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.

Quantum nonlocality does not exist. [PDF]
Proc Natl Acad Sci U S A, 2014 Significance I show that quantum nonlocality is an artifact of the assumption that observers obey the laws of classical mechanics, whereas observed systems obey quantum mechanics. Locality is restored if observed and observer both obey quantum mechanics, as in the many-worlds interpretation (MWI).

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.

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.

Quantum steering with vector vortex photon states with the detection loophole closed
npj Quantum Information, 2022 Violating a nonlocality inequality enables the most powerful remote quantum information tasks and fundamental tests of quantum physics. Loophole-free photonic verification of nonlocality has been achieved with polarization-entangled photon pairs, but not
