Reply to the Comment by A.J. Leggett and Anupam Garg [PDF]
, 2010 In their comment[1] on our Letter [arXiv:0907.0767], Leggett and Garg claim that they have introduced in their original paper (LG1) a dependence on measurement times.

Spin Bath Decoherence of Quantum Entanglement [PDF]
, 2005 We study an analytically solvable model for decoherence of a two spin system embedded in a large spin environment. As a measure of entanglement, we evaluate the concurrence for the Bell states (Einstein-Podolsky-Rosen pairs).

Entanglement in a first-order quantum phase transition [PDF]
, 2016 4 págs.; 3 figs.; PACS number(s): 03.65.Ud, 03.67.Mn, 73.43.NqThe entanglement properties of the ground state for a system of spins half embedded in a magnetic field were investigated. A first-order transition was obtained at zero field.

Relativity, anomalies and objectivity loophole in recent tests of local realism
Open Physics, 2017 Local realism is in conflict with special quantum Bell-type models. Recently, several experiments have demonstrated violation of local realism if we trust their setup assuming special relativity valid.

Generating and protecting correlated quantum states under collective dephasing
New Journal of Physics, 2016 We study the collective dephasing process of a system of non-interacting atomic qubits, immersed in a spatially uniform magnetic field of fluctuating intensity.

A simple proof of monogamy of entanglement [PDF]
, 2006 Monogamy of entanglement means that an entangled state cannot be shared with many parties. The more parties, the less entanglement between them. In this paper, we give a simple proof of this property and provide an upper bound of the number of parties ...

Local model of a qubit in the interferometric setup
New Journal of Physics, 2015 We consider a typical realization of a qubit as a single particle in two-path interferometric circuits built from phase shifters, beam splitters and detectors. This framework is often taken as a standard example illustrating various paradoxes and quantum

New Journal of Physics, 2015 Quantum contextuality is one of the fundamental notions in quantum mechanics. Proofs of the Kochen–Specker theorem and noncontextuality inequalities are two means for revealing the contextuality phenomenon in quantum mechanics.

Nonrecurrence and Bell-like inequalities
Open Physics, 2017 The general class, Λ, of Bell hidden variables is composed of two subclasses ΛR and ΛN such that ΛR⋃ΛN = Λ and ΛR∩ ΛN = {}. The class ΛN is very large and contains random variables whose domain is the continuum, the reals.
