Symmetry enriched phases of quantum circuits
Yimu Bao, Soonwon Choi, Ehud Altman
Quantum circuits consisting of random unitary gates and subject to local measurements have been shown to undergo a phase transition, tuned by the rate of measurement, from a state…

Theory of the phase transition in random unitary circuits with measurements
Yimu Bao, Soonwon Choi, Ehud Altman
We present a theory of the entanglement transition tuned by measurement strength in qudit chains evolved by random unitary circuits and subject to either weak or random projective…

Quantum Error Correction in Scrambling Dynamics and Measurement-Induced Phase Transition
Soonwon Choi, Yimu Bao, Xiao-Liang Qi +1
We analyze the dynamics of entanglement entropy in a generic quantum many-body open system from the perspective of quantum information and error corrections. We introduce a random…
