Coherence-Assisted Superradiant Laser with Hz Linewidth and W Power
Guohui Dong, Yao Yao, Peng Zhang +1
The superradiant laser, based on the clock transition between the electric ground state S and the metastable state P of fermionic alkaline-earth(-like) atoms, has b…
Coexistence of directed momentum current and ballistic energy diffusion in coupled non-Hermitian kicked rotors
Jian-Zheng Li, Wen-Lei Zhao, Jie Liu
We numerically investigate the quantum transport in a coupled kicked rotors with the -symmetric potential. We find that the spontaneous -symmetry breaki…
Quantum algorithms for optimal effective theory of many-body systems
Yongdan Yang, Zongkang Zhang, Xiaosi Xu +2
A common situation in quantum many-body physics is that the underlying theories are known but too complicated to solve efficiently. In such cases one usually builds simpler effecti…
Quantum Error Mitigation
Zhenyu Cai, Ryan Babbush, Simon C. Benjamin +5
For quantum computers to successfully solve real-world problems, it is necessary to tackle the challenge of noise: the errors which occur in elementary physical components due to u…
A pseudo-fermion method for the exact description of fermionic environments: from single-molecule electronics to Kondo resonance
Mauro Cirio, Neill Lambert, Pengfei Liang +5
We develop a discrete fermion approach for modelling the strong interaction of an arbitrary system interacting with continuum electronic reservoirs. The approach is based on a pseu…
Approximate distillation of quantum coherence
C. L. Liu, C. P. Sun
Coherence distillation is a basic information-theoretic task in the resource theory of coherence. In this paper, we develop the framework of the approximate coherence distillation…
