Quantum Recurrence Plot Algorithm Based on Quantum Principal Component Analysis
Hanhuai Zhu, Jingjing Huang, Zhi-Xi Wang +1
Recurrence Plot (RP) is a method employed to analyze the periodicity, chaoticity, and nonlinear characteristics of complex systems. Quantum Principal Component Analysis (QPCA), on…
Quantum separability criteria from bipartite systems to multipartite systems based on generalized Bloch representation
Linwei Li, Chunlin Yang, Hongmei Yao +3
Quantum entanglement serves as a fundamental resource in quantum information theory. This paper presents a comprehensive framework of separability criteria for detecting bipartite…
Variational Quantum Algorithm for Constrained Combinatorial Optimization Problems
Hui-Min Li, Yuan-Liang Han, Zhi-Xi Wang +1
While variational quantum algorithms (VQAs) have demonstrated considerable success in unconstrained optimization, their application to constrained combinatorial problems face a tra…
Variational quantum algorithm for generalized eigenvalue problems of non-Hermitian systems
Jiaxin Li, Zhaobing Fan, Hongmei Yao +5
Non-Hermitian generalized eigenvalue problems (GEPs) play a significant role in many practical applications, such as mechanical engineering. Based on the generalized Schur decompos…
