Tabletop reversibility of phase-covariant operations
Fangzhen Chen, Xueyuan Hu
Irreversibility and time-translation symmetry are both fundamental in open quantum dynamics, and it is of great importance to study the interplay between them. In this paper, we st…
Exploring the gap between thermal operations and enhanced thermal operations
Yuqiang Ding, Feng Ding, Xueyuan Hu
The gap between thermal operations (TO) and enhanced thermal operations (EnTO) is an open problem raised in [Phys. Rev. Lett. 115, 210403 (2015)]. It originates from the limitation…
Amplifying asymmetry with correlated catalysts
Feng Ding, Xueyuan Hu, Heng Fan
We investigate the basic constraint on amplifying the asymmetry in quantum states with correlated catalysts. Here a correlated catalyst is a finite-dimensional auxiliary, which exa…
Masking Quantum Information on Hyperdisks
Feng Ding, Xueyuan Hu
Masking information is a protocol that encodes quantum information into a bipartite entangled state while the information is completely unknown to local systems. This paper explici…
Coherence non-activating measurement
Xueyuan Hu
We define the coherence non-activating measurement as the positive operator-valued measurement which gives the same result whether or not the coherence in a quantum state is destro…
Thermal Operations Involving a Single-mode Bosonic Bath
Xueyuan Hu
We study the limitations on coherence evolutions under the constraints of thermodynamic laws, and focus on the optimal thermal operations (TO) reaching the bounds. For qubit case,…
