More efficient Bell inequalities for Werner states

T. Vértesi

In this paper we study the nonlocal properties of two-qubit Werner states parameterized by the visibility parameter 0<p<1. New family of Bell inequalities are constructed which pro…

Efficiency of higher dimensional Hilbert spaces for the violation of Bell inequalities

K. F. Pál, T. Vértesi

We have determined numerically the maximum quantum violation of over 100 tight bipartite Bell inequalities with two-outcome measurements by each party on systems of up to four dime…

Generalized Clauser-Horne-Shimony-Holt inequalities maximally violated by higher dimensional systems

T. Vértesi, K. F. Pál

Imagine two parties, Alice and Bob who share an entangled quantum state. A well-established result that if Alice performs two-outcome measurement on the portion of the state in her…

Discrimination between evolution operators

T. Vértesi, R. Englman

Under broad conditions, evolutions due to two different Hamiltonians are shown to lead at some moment to orthogonal states. For two spin-1/2 systems subject to precession by differ…

Genuine tripartite entanglement in the non-interacting Fermi gas

T. Vértesi

We study genuine tripartite entanglement shared among the spins of three localized fermions in the non-interacting Fermi gas at zero temperature. Firstly, we prove analytically wit…

Perturbative Analysis of Possible Failures in the Traditional Adiabatic Conditions

T. Vértesi, R. Englman

Recently, Marzlin and Sanders (2004) demonstrated an inconsistency when the adiabatic approximation was applied to specific, "inverse" time-evolving systems. Following that, Tong e…
