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…
Measurement-induced criticality in -symmetric quantum automaton circuits
Yiqiu Han, Xiao Chen
We study entanglement dynamics in hybrid -symmetric quantum automaton circuits subject to local composite measurements. We show that there exists an entanglement phas…
Multifractality in non-unitary random dynamics
Jason Iaconis, Xiao Chen
We explore the multifractality of the steady state wave function in non-unitary random quantum dynamics in one dimension. We focus on two classes of random systems: the hybrid Clif…
Entanglement phase transitions in random stabilizer tensor networks
Zhi-Cheng Yang, Yaodong Li, Matthew P. A. Fisher +1
We explore a class of random tensor network models with "stabilizer" local tensors which we name Random Stabilizer Tensor Networks (RSTNs). For RSTNs defined on a two-dimensional s…
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…
Universal Entanglement Transitions of Free Fermions with Long-range Non-unitary Dynamics
Pengfei Zhang, Chunxiao Liu, Shao-Kai Jian +1
Non-unitary evolution can give rise to novel steady states classified by their entanglement properties. In this work, we aim to understand its interplay with long-range hopping tha…
Emergent Replica Conformal Symmetry in Non-Hermitian SYK Chains
Pengfei Zhang, Shao-Kai Jian, Chunxiao Liu +1
Recently, the steady states of non-unitary free fermion dynamics are found to exhibit novel critical phases with power-law squared correlations and a logarithmic subsystem entangle…
Non-unitary Entanglement Dynamics in Continuous Variable Systems
Tianci Zhou, Xiao Chen
We construct a random unitary Gaussian circuit for continuous-variable (CV) systems subject to Gaussian measurements. We show that when the measurement rate is nonzero, the steady…
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…
