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…
Conformal invariance and quantum non-locality in critical hybrid circuits
Yaodong Li, Xiao Chen, Andreas W. W. Ludwig +1
We establish the emergence of a conformal field theory (CFT) in a (1+1)-dimensional hybrid quantum circuit right at the measurement-driven entanglement transition by revealing spac…
