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…
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…
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 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…
