A unified framework for efficient quantum simulation of nonlinear spectroscopy
Long Xiong, Xiaoyang Wang, Xiaoxia Cai +1
Nonlinear spectroscopy is a cornerstone of quantum science, providing unique access to multi-point correlations, quantum coherence, and couplings that are invisible to linear metho…
Characterizing Topological Phase Transition in Non-Hermitian Systems
ZhaoXiang Fang, Yongxu Fu, Guang-Can Guo +1
We propose and present a concept of Topological Distance (TD), obtained from the integration of trace distance over the generalized Brillouin zone, in order to characterize the top…
Computing n-time correlation functions without ancilla qubits
Xiaoyang Wang, Long Xiong, Xiaoxia Cai +1
The -time correlation function is pivotal for establishing connections between theoretical predictions and experimental observations of a quantum system. Conventional methods fo…
Hermitian and Non-Hermitian Topological Transitions Characterized by Manifold Distance
ZhaoXiang Fang, Ming Gong, Guang-Can Guo +2
Topological phases are generally characterized by topological invariants denoted by integer numbers. However, different topological systems often require different topological inva…
Distance between two manifolds, topological phase transitions and scaling laws
ZhaoXiang Fang, Ming Gong, Guang-Can Guo +2
Topological phases are generally characterized by topological invariants denoted by integer numbers. However, different topological systems often require different topological inva…
Entanglement distribution in fermion model with long-range interaction
Long Xiong, Yuexing Huang, Yuchun Wu +3
How two-party entanglement (TPE) is distributed in the many-body systems? This is a fundamental issue because the total TPE between one party with all the other parties, $\mathcal{…
Scaling of finite size effect of -Rényi entropy in disjointed intervals under dilation
Long Xiong, Shunyao Zhang, Guangcan Guo +1
The -Rényi entropy in the gapless models have been obtained by the conformal field theory, which is exact in the thermodynamic limit. However, the calculation of its finite size…
