Complex semiclassical theory for non-Hermitian quantum systems
Guang Yang, Yongkang Li, Yongxu Fu +2
Non-Hermitian quantum systems exhibit fascinating characteristics such as non-Hermitian topological phenomena and skin effect, yet their studies are limited by the intrinsic diffic…
Self-Similarity Among Energy Eigenstates
Zhelun Zhang, Zhenduo Wang, Biao Wu
In a quantum system, different energy eigenstates have different properties or features, allowing us define a classifier to divide them into different groups. We find that the rati…
Quantum Dropout: On and Over the Hardness of Quantum Approximate Optimization Algorithm
Zhen-Duo Wang, Pei-Lin Zheng, Biao Wu +1
A combinatorial optimization problem becomes very difficult in situations where the energy landscape is rugged, and the global minimum locates in a narrow region of the configurati…
Lorentz Quantum Computer
Wenhao He, Zhenduo Wang, Biao Wu
A theoretical model of computation is proposed based on Lorentz quantum mechanics. Besides the standard qubits, this model has an additional bit, which we call hyperbolic bit (or h…
Microscope for Quantum Dynamics with Planck Cell Resolution
Zhenduo Wang, Jiajin Feng, Biao Wu
We introduce the out-of-time-correlation(OTOC) with the Planck cell resolution. The dependence of this OTOC on the initial state makes it function like a microscope, allowing us to…
Genuine Quantum Chaos and Physical Distance Between Quantum States
Zhenduo Wang, Yijie Wang, Biao Wu
We show that there is genuine quantum chaos despite that quantum dynamics is linear. This is revealed by introducing a physical distance between two quantum states. Qualitatively d…
Generalized Wigner-von Neumann entropy and its typicality
Zhigang Hu, Zhenduo Wang, Biao Wu
We propose a generalization of the quantum entropy introduced by Wigner and von Neumann in 1929 [Zeitschrift für Physik 57, 30 (1929)]. Our generalization is applicable to both qua…
