Non-unitary free boson dynamics and the boson sampling problem
Xiao Chen
We explore the free boson unitary dynamics subject to repeated random forced measurement. The input state is chosen as a Fock state in real space with the particle number conserved…
Quantum error as an emergent magnetic field
Shao-Kai Jian, Chunxiao Liu, Xiao Chen +2
We investigate the effect of quantum errors on a monitored Brownian Sachdev-Ye-Kitaev (SYK) model featuring a measurement-induced phase transition that can be understood as a symme…
Quantum criticality in the nonunitary dynamics of -dimensional free fermions
Qicheng Tang, Xiao Chen, W. Zhu
We explore the nonunitary dynamics of -dimensional free fermions and show that the obtained steady state is critical regardless the strength of the nonunitary evolution. Num…
Yang-Lee edge singularity triggered entanglement transition
Shao-Kai Jian, Zhi-Cheng Yang, Zhen Bi +1
We show that a class of symmetric non-Hermitian Hamiltonians realizing the Yang-Lee edge singularity exhibits an entanglement transition in the long-time steady stat…
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-induced phase transitions in quantum automaton circuits
Jason Iaconis, Andrew Lucas, Xiao Chen
We study the entanglement dynamics in a generic quantum automaton circuit subjected to projective measurements. We design an efficient algorithm which not only allows us to perform…
