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…
Cooling and work extraction under memory-assisted Markovian thermal processes
Yuancheng Liu, Xueyuan Hu
We investigate the limits on cooling and work extraction via Markovian thermal processes assisted by a finite-dimensional memory. Here the memory is a -dimensional quantum syste…
Resource theory of dephasing estimation in multiqubit systems
Zishi Chen, Xueyuan Hu
We present a resource theory to investigate the power of a multqubit system as a probe in the task of dephasing estimation. Our approach employs the quantum Fisher information abou…
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,…
Quantitative Coherence Witness for Finite Dimensional States
Huizhong Ren, Anni Lin, Siying He +1
We define the stringent coherence witness as an observable which has zero mean value for all of incoherent states and hence a nonzero mean value indicates the coherence. The existe…
Quantum coherence and geometric quantum discord
Ming-Liang Hu, Xueyuan Hu, Jie-Ci Wang +3
Quantum coherence and quantum correlations are of fundamental and practical significance for the development of quantum mechanics.They are also cornerstones of quantum computation…
Entanglement witness game
Xing Chen, Xueyuan Hu, D. L. Zhou
Motivated by Buscemi's semi-quantum nonlocal game [PRL 108, 200401(2012)], We propose an entanglement witness game, a quantum game based on entanglement witness. Similar as the sem…
Resource Destroying Maps
Zi-Wen Liu, Xueyuan Hu, Seth Lloyd
Resource theory is a widely-applicable framework for analyzing the physical resources required for given tasks, such as computation, communication, and energy extraction. In this p…
Coherence non-generating channels
Xueyuan Hu
We define the coherence non-generating channel as the completely positive trace-preserving map which does not generate quantum coherence from an incoherent state. The incoherent op…
Extracting quantum coherence via steering
Xueyuan Hu, Heng Fan
As the precious resource for quantum information processing, quantum coherence can be created remotely if the involved two sites are quantum correlated. It can be expected that the…
Quantum coherence of steered states
Xueyuan Hu, Antony Milne, Boyang Zhang +1
Lying at the heart of quantum mechanics, coherence has recently been studied as a key resource in quantum information theory. Quantum steering, a fundamental notion originally cons…
Effect of Local Channels on Quantum Steering Ellipsoids
Xueyuan Hu, Heng Fan
The effect of a local trace-preserving single-qubit channel on a two-qubit state is investigated in the picture of the quantum steering ellipsoids (QSE). The phenomenon of locally…

We prove that, when two local quantum channels are used paralleled, the quantum-correlating power (QCP) of the composed channel is no less than the sum of QCP of the two channels.…

Liming Zhao, Xueyuan Hu, R. -H. Yue +1
We define genuine total, classical and quantum correlations in tripartite systems. The measure we propose is based on the idea that genuine tripartite correlation exists if and onl…
Quantum-correlating power of local quantum channels
Xueyuan Hu, Heng Fan, D. L. Zhou +1
Quantum correlation can be created by local operations from a classically correlated state. We define quantum-correlating power (QCP) of a local quantum channel as the maximum amou…
