Subsystem symmetry, spin glass order, and criticality from random measurements in a two-dimensional Bacon-Shor circuit
Vaibhav Sharma, Chao-Ming Jian, Erich J Mueller
We study a 2D measurement-only random circuit motivated by the Bacon-Shor error correcting code. We find a rich phase diagram as one varies the relative probabilities of measuring…
Entanglement in one-dimensional critical state after measurements
Zhou Yang, Dan Mao, Chao-Ming Jian
The entanglement entropy (EE) of the ground state of a one-dimensional Hamiltonian at criticality has a universal logarithmic scaling with a prefactor given by the central charge $…
Quantum Simulation of the Non-Fermi-Liquid State of Sachdev-Ye-Kitaev Model
Zhihuang Luo, Yi-Zhuang You, Jun Li +5
The Sachdev-Ye-Kitaev (SYK) model incorporates rich physics, ranging from exotic non-Fermi liquid states without quasiparticle excitations, to holographic duality and quantum chaos…
Superdensity Operators for Spacetime Quantum Mechanics
Jordan Cotler, Chao-Ming Jian, Xiao-Liang Qi +1
We introduce superdensity operators as a tool for analyzing quantum information in spacetime. Superdensity operators encode spacetime correlation functions in an operator framework…
