Manipulating the direction of one-way steering in an optomechanical ring cavity
Jamal El Qars, Benachir Boukhris, Ahmed Tirbiyine +1
Quantum steering refers to the apparent possibility of exploiting nonseparable quantum correlations to remotely influence the quantum state of an observer via local measurements. D…
Demonstration of monogamy laws for Gaussian steering in optomechanics
J El Qars, M Daoud, R Ahl Laamara +1
Secrecy and security are crucial in communication. So, quantum secret sharing protocol has recently been proposed to distribute a secret message to a set of parties, where the deco…
Gaussian quantum steering in a nondegenerate three-level laser
Benachir Boukhris, Ahmed Tirbiyine, Jamal El Qars
Steering is a type of nonseparable quantum correlation, where its inherent asymmetric feature makes it distinct from Bell-nonlocality and entanglement. In this paper, we investigat…
Distributing long-distance trust in optomechanics
Jamal El Qars
Quantum steering displays an inherent asymmetric property that differs from entanglement and Bell nonlocality. Besides being of fundamental interest, steering is relevant to many a…
Unidirectional Gaussian One-Way Steering
Jamal El Qars
Steering is a type of quantum nonlocality that exhibits an inherent asymmetry between two observers. In a nondegenerate three-level laser coupled to a two-mode squeezed vacuum rese…
Quantum correlations beyond entanglement in a double-cavity opto-mechanical system
J. El Qars, M. Daoud, Ahl Laamara
In this paper we investigate the robustness of the quantum correlations against the environment effects in various opto-mechanical bipartite systems. For two spatially separated op…
