Entanglement preparation and work extraction wiht a truly quantum Maxwell demon

2021 · arXiv (Cornell University)

The information of a quantum system acquired by a Maxwell demon can be used for either work extraction or entanglement preparation. We study these two tasks by using a thermal qubit, in which a demon …

Quantum information masking of an arbitrary unknown state can be realized in the multipartite lower-dimensional systems

2023 · Physica Scripta

Abstract Quantum information masking is a protocol that hides the original quantum information from subsystems and spreads it over quantum correlation, which is available to multipartite except bipartite systems. In this work, we explicitly study …
