Experimental demonstration of scalable cross-entropy benchmarking to detect measurement-induced phase transitions on a superconducting quantum processor
Hirsh Kamakari, Jiace Sun, Yaodong Li +5
Quantum systems subject to random unitary evolution and measurements at random points in spacetime exhibit entanglement phase transitions which depend on the frequency of these mea…

Quantum Zeno Effect and the Many-body Entanglement Transition
Yaodong Li, Xiao Chen, Matthew P. A. Fisher
We introduce and explore a one-dimensional "hybrid" quantum circuit model consisting of both unitary gates and projective measurements. While the unitary gates are drawn from a ran…
