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…
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…
Many-body quantum dynamics slows down at low density
Xiao Chen, Yingfei Gu, Andrew Lucas
We study quantum many-body systems with a global U(1) conservation law, focusing on a theory of interacting fermions with charge conservation, or interacting spins with one…
Emergent conformal symmetry in non-unitary random dynamics of free fermions
Xiao Chen, Yaodong Li, Matthew P. A. Fisher +1
We present random quantum circuit models for non-unitary quantum dynamics of free fermions in one spatial dimension. Numerical simulations reveal that the dynamics tends towards st…
