Ultrafast Entanglement Dynamics in Monitored Quantum Circuits
Shengqi Sang, Zhi Li, Timothy H. Hsieh +1
Projective measurement, a basic operation in quantum mechanics, can induce seemingly nonlocal effects. In this work, we analyze such effects in many-body systems by studying the no…

Entanglement Negativity at Measurement-Induced Criticality
Shengqi Sang, Yaodong Li, Tianci Zhou +3
We propose entanglement negativity as a fine-grained probe of measurement-induced criticality. We motivate this proposal in stabilizer states, where for two disjoint subregions, co…

Measurement Protected Quantum Phases
Shengqi Sang, Timothy H. Hsieh
We introduce a class of hybrid quantum circuits, with random unitaries and projective measurements, which host long-range order in the area law entanglement phase of the steady sta…
