Satellite-based quantum communication channels are important for ultra-long distances.
Given the short duration of a satellite pass, it can be challenging to efficiently connect …

This study proposes to enhance entanglement and control quantum steering via dissipative
coupling in an open cavity magnomechanical system connected to a common reservoir …

A workflow for evaluation of entanglement source quality is proposed. Based on quantum
state density matrices obtained from theoretical models and experimental data, we make an …

Satellite based quantum communications will enable long distances, or even global
quantum networking, of quantum optical signals. We give an overview on the activities …

In this paper, we show that a (2, 3) discrete variable threshold quantum secret sharing
scheme of secure direct communication can be achieved based on recurrence using the …

Quantum key distribution (QKD) offers means to transmit data with unprecedented security,
ultimately promising to remove the need to trust anything or anyone involved but the laws of …
