Realization of decoherence-induced averaged symmetry-protected topological phases on quantum processors
Ruizhe Shen, Xue-Jia Yu, Ching Hua Lee
Symmetry-protected topological (SPT) phases are conventionally formulated for pure states protected by exact symmetries. In open quantum systems, however, decoherence generates mix…
Measurement-Induced Entanglement Phase Transition in Free Fermion Systems
Han-Ze Li, Jian-Xin Zhong, Xue-Jia Yu
Measurement-induced entanglement phase transitions (MIET) highlight how local measurements drive quantum systems between area-law and volume-law entangled states. This review surve…
Experimental demonstration of spontaneous symmetry breaking with emergent multi-qubit entanglement
Ri-Hua Zheng, Wen Ning, Jia-Hao Lü +8
Spontaneous symmetry breaking (SSB) is crucial to the occurrence of phase transitions. Once a phase transition occurs, a quantum system presents degenerate eigenstates that lack th…
Implementation and topological characterization of Weyl exceptional rings in quantum-mechanical systems
Hao-Long Zhang, Pei-Rong Han, Xue-Jia Yu +8
Non-Hermiticity can lead to the emergence of many intriguing phenomena that are absent in Hermitian systems, enabled by exceptional topological defects, among which Weyl exceptiona…
