The Lieb-Robinson light cone for power-law interactions
Minh C. Tran, Andrew Y. Guo, Christopher L. Baldwin +3
The Lieb-Robinson theorem states that information propagates with a finite velocity in quantum systems on a lattice with nearest-neighbor interactions. What are the speed limits on…
Optimal State Transfer and Entanglement Generation in Power-law Interacting Systems
Minh C. Tran, Abhinav Deshpande, Andrew Y. Guo +2
We present an optimal protocol for encoding an unknown qubit state into a multiqubit Greenberger-Horne-Zeilinger-like state and, consequently, transferring quantum information in l…
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…
Bound on quantum scrambling with all-to-all interactions
Chao Yin, Andrew Lucas
We prove bounds on operator growth and infinite temperature out-of-time-ordered correlators in many-body systems with spin- degrees of freedom which interact via t…
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…
