Bosonic bunching reveals strong contextual behaviour

Pawel Kurzynski, Akihito Soeda, Jayne Thompson +1

We show that violation of Klyachko-Can-Binicioglu-Shumovsky [Phys. Rev. Lett. {\bf 101}, 020403 (2008)] pentagram-like inequality can exceed provided that exclusive even…

Quantum walk as a generalized measuring device

Pawel Kurzynski, Antoni Wojcik

We show that a one-dimensional discrete time quantum walk can be used to implement a generalized measurement in terms of positive operator value measure (POVM) on a single qubit. M…

Practically state-independent test of contextuality with 9 observables

Pawel Kurzynski, Dagomir Kaszlikowski

We propose a test of quantum contextuality for a single three-level system that uses nine projective measurements. It has a form of an inequality that has to be satisfied by any no…

The relation between nonlocality and contextuality for a biphoton

Akihito Soeda, Pawel Kurzynski, Ravishankar Ramanathan +2

We investigate the set of qutrit states in terms of symmetric states of two qubits that violate the minimal contextual inequality, namely the Klyachko-Can-Binicoglu-Shumovsky (KCBS…

Generalized monogamy of contextual inequalities from the no-disturbance principle

Ravishankar Ramanathan, Akihito Soeda, Pawel Kurzynski +1

In this paper we demonstrate that the property of monogamy of Bell violations seen for no-signaling correlations in composite systems can be generalized to the monogamy of contextu…

Entropic Test of Quantum Contextuality

Pawel Kurzynski, Ravishankar Ramanathan, Dagomir Kaszlikowski

We study the contextuality of a three-level quantum system using classical conditional entropy of measurement outcomes. First, we analytically construct the minimal configuration o…
