Detecting and quantifying entanglement on near-term quantum devices
Kun Wang, Zhixin Song, Xuanqiang Zhao +2
Quantum entanglement is a key resource in quantum technology, and its quantification is a vital task in the current Noisy Intermediate-Scale Quantum (NISQ) era. This paper combines…
Physical Implementability of Linear Maps and Its Application in Error Mitigation
Jiaqing Jiang, Kun Wang, Xin Wang
Completely positive and trace-preserving maps characterize physically implementable quantum operations. On the other hand, general linear maps, such as positive but not completely…
Finite Block Length Analysis on Quantum Coherence Distillation and Incoherent Randomness Extraction
Masahito Hayashi, Kun Fang, Kun Wang
We give the first systematic study on the second order asymptotics of the operational task of coherence distillation with and without assistance. In the unassisted setting, we intr…
Permutation Enhances Classical Communication Assisted by Entangled States
Kun Wang, Masahito Hayashi
We give a capacity formula for the classical communication over a noisy quantum channel, when local operations and global permutations allowed in the encoding and bipartite states…
