Hardness of observing strong-to-weak symmetry breaking
Xiaozhou Feng, Zihan Cheng, Matteo Ippoliti
Spontaneous symmetry breaking (SSB) is the cornerstone of our understanding of quantum phases of matter. Recent works have generalized this concept to the domain of mixed states in…

Postselection-free experimental observation of the measurement-induced phase transition in circuits with universal gates
Xiaozhou Feng, Jeremy Côté, Stefanos Kourtis +1
Monitored many-body systems can exhibit a phase transition between entangling and disentangling dynamical phases by tuning the strength of measurements made on the system as it evo…
