Evaluating noises of fast-simulated boson sampling with statistical benchmark methods
Yang Ji, Yongjin Ye, Qiao Wang +5
It is important to know noise levels of boson sampling in order to cautiously demonstrate the quantum computational advantage or realize certain tasks. Based on those statistical b…
Hidden weak-pairing superconductivity of non-interacting anyons obeying statistics
Zheng-Duo Fan, Ashvin Vishwanath, Zijian Wang
We show that a non-interacting gas of charge- anyons with exchange statistics can superconduct through a hidden weak-pairing mechanism. Such an anyon gas arises nat…
Extended validations on photon number resolving detector based Gaussian boson sampling with low noises
Yang Ji, Yongzheng Wu, Shi Wang +3
Gaussian boson sampling (GBS) is a variety of boson sampling overcoming the stable single-photon preparation difficulty of the later. However, like those in the original version, n…
Topologically Ordered Steady States in Open Quantum Systems
Zijian Wang, Xu-Dong Dai, He-Ran Wang +1
The interplay between dissipation and correlation can lead to novel emergent phenomena in open systems. Here we investigate ``steady-state topological order'' defined by the robust…
Spontaneous symmetry breaking in open quantum systems: strong, weak, and strong-to-weak
Ding Gu, Zijian Wang, Zhong Wang
Depending on the coupling to the environment, symmetries of open quantum systems manifest in two distinct forms, the strong and the weak. We study the spontaneous symmetry breaking…
Non-Bloch self-energy of dissipative interacting fermions
He-Ran Wang, Zijian Wang, Zhong Wang
The non-Hermitian skin effect describes the phenomenon of exponential localization of single-particle eigenstates near the boundary of the system. We consider its generalization to…
