Mathematically Proving Bell Nonlocality Motivated by the GHZ Argument
IEEE Access, 2021 Bell nonlocality of quantum states is an important resource in quantum information and then has various applications. It is usually detected by the violation of some Bell’s inequalities and the all-versus-nothing test. In the present paper, we aim

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 outputs, and the nonlocal boxes are realized through appropriate measurements on polarization ...

Reflections on the Role of Entanglement in the Explanation of Quantum Computational Speedup [PDF]
, 2011 Of the many and varied applications of quantum information theory, perhaps the most fascinating is the sub-field of quantum computation. In this sub-field, computational algorithms are designed which utilise the resources available in quantum systems in ...

Entanglement and quantum nonlocality demystified [PDF]
AIP Conference Proceedings, 2012 Quantum nonlocality is presented often as the most remarkable and inexplicable phenomenon known to modern science which was confirmed in the experiments proving the violation of Bell Inequalities (BI). It has been known already for a long time that the probabilistic models used to prove BI for spin polarization correlation experiments (SPCE) are ...

Quantum information theory and the foundations of quantum mechanics
, 2004 This thesis is a contribution to the debate on the implications of quantum information theory for the foundational problems of quantum mechanics. In Part I an attempt is made to shed some light on the nature of information and quantum information theory.

Holism, Physical Theories and Quantum Mechanics [PDF]
, 2004 Motivated by the question what it is that makes quantum mechanics a holistic theory (if so), I try to define for general physical theories what we mean by `holism'.

Bell nonlocality using tensor networks and sparse recovery
Physical Review Research, 2020 Bell's theorem, stating that quantum predictions are incompatible with a local hidden variable description, is a cornerstone of quantum theory and at the center of many quantum information processing protocols.

Quantifying Quantumness of Channels Without Entanglement
PRX Quantum, 2022 Quantum channels breaking entanglement, incompatibility, or nonlocality are defined as such because they are not useful for entanglement-based, one-sided device-independent, or device-independent quantum-information processing, respectively.

Quantum Mechanics versus Special Relativity: A forgotten conflict [PDF]
, 2008 Despite the widespread assumptions on the compatibility between non-relativistic quantum mechanics and special relativity, there still remains a considerable amount of unresolved problems to which few authors explicitly pay attention.
