Strong-to-Weak Spontaneous Symmetry Breaking in a D Transverse-Field Ising Model under Decoherence
Yi-Ming Ding, Yuxuan Guo, Zhen Bi +1
Decoherence in many-body quantum systems can give rise to intrinsically mixed-state phases and phase transitions beyond the pure-state paradigm. Here we study the D transver…

Tower of Structured Excited States from Measurements
Yuxuan Guo, Yuto Ashida
Preparing highly entangled quantum states is a key challenge in quantum metrology and quantum information science. Measurements, especially those of global observables, offer a sim…

Two-dimensional symmetry-protected topological phases and transitions in open quantum systems
Yuxuan Guo, Yuto Ashida
We investigate the influence of local decoherence on a symmetry-protected topological (SPT) phase of the two-dimensional (2D) cluster state. Mapping the 2D cluster state under deco…
