DOI: 10.1103/physrevlett.130.160201
Abstract: We introduce a family of entanglement witnesses for continuous variable systems, which rely on the sole assumption that their dynamics is that of coupled harmonic oscillators at the time of the test. Entanglement is inferred… read more here.

DOI: 10.1109/access.2022.3185403
Abstract: In the practical context of quantum networks, quantum teleportation plays a key role in transmitting quantum information. In the process of teleportation, a maximally entangled pair is consumed. Through this paper, an efficient scheme of… read more here.
