Quantum network coding (QNC) aims at alleviating quantum communication congestion in
quantum networks. Although several QNC protocols have been presented, they cannot meet …

Quantum key agreement (QKA) is an important cryptographic primitive that plays a pivotal
role in private communications. However, in practical implementations of QKA, the flaws in …

In this paper, we theoretically study the concept of the wave–particle duality of two entangled
neutral Bragg diffracted atoms. This is an extension of a recent study where the same idea …

Hyperentangled swap** is a quantum communication technique that involves the
exchange of hyperentangled states, which are quantum states entangled in multiple …

We propose various schemes for the generation of cavity field entangled states including
Bell states, W‐state and GHZ states. The fundamental ingredient of all such engineering …

In this paper, firstly, we consider bipartite entanglement between each part of an
optomechanical cavity composed of one-dimensional Bose–Einstein condensate (BEC). We …
