Zeno-Enhanced Probabilistic Error Cancellation with Quantum Error Detection Codes
Yi Yuan, Yuanchen Zhao, Dong E. Liu
Probabilistic error cancellation (PEC) is unbiased but suffers exponential sampling overhead set by noise-weighted circuit volume, whereas quantum error-detecting codes (QEDCs) rem…

Dephasing-induced Quantum Hall Criticality in the Quantum Anomalous Hall system
Fei Yang, Dong E. Liu
Conventional wisdom holds that static disorder is indispensable to the integer quantum Hall effect, underpinning both quantized plateaus and the plateau-plateau transition. We show…

Work Statistics and Adiabatic Assumption in Nonequilibrium Many-Body Theory
Yi Zuo, Qinghong Yang, Bang-Gui Liu +1
Keldysh field theory, based on adiabatic assumptions, serves as an widely used framework for addressing nonequilibrium many-body systems. Nonetheless, the validity of such adiabati…
