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…
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…
Exponentially Enhanced Tripartite Coupling in Quantum Nonlinear Magnonics
Xue-Chun Chen, Zi-Jie Wang, Sheng-Bo Zheng +2
Strong and controllable tripartite interactions play a pivotal role in quantum information and nonlinear quantum optics, yet challenging to realize. In this work, we propose a hybr…
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…
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…
Anomaly in open quantum systems and its implications on mixed-state quantum phases
Zijian Wang, Linhao Li
In this paper, we develop a systematic approach to characterize the 't Hooft anomaly in open quantum systems. Owing to nontrivial couplings to the environment, symmetries in such s…
Steady-state topological order
Xu-Dong Dai, Zijian Wang, He-Ran Wang +1
We investigate a generalization of topological order from closed systems to open systems, for which the steady states take the place of ground states. We construct typical lattice…
Intrinsic Mixed-state Topological Order
Zijian Wang, Zhengzhi Wu, Zhong Wang
Decoherence is a major obstacle to the preparation of topological order in noisy intermediate-scale quantum devices. Here, we show that decoherence can also give rise to new types…
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…
