From Quantum Circuits with Ultraslow Dynamics to Classical Plaquette Models
Vikram Ravindranath, Hanchen Liu, Xiao Chen
We introduce a family of hybrid quantum circuits involving unitary gates and projective measurements that display a measurement-induced phase transition. Remarkably, the volume-law…

Coherent error induced phase transition
Hanchen Liu, Xiao Chen
We investigate the stability of logical information in quantum stabilizer codes subject to coherent unitary errors. Beginning with a logical state, we apply a random unitary error…
