Continuous Hamiltonian dynamics on digital quantum computers without discretization error
Etienne Granet, Henrik Dreyer
We introduce an algorithm to compute Hamiltonian dynamics on digital quantum computers that requires only a finite circuit depth to reach an arbitrary precision, i.e. achieves zero…
Antiunitary symmetry breaking and a hierarchy of purification transitions in Floquet non-unitary circuits
Carolyn Zhang, Etienne Granet
We consider how a maximally mixed state evolves under Floquet non-unitary circuits with an antiunitary symmetry that squares to identity, that serves as a generalized $\ma…
Wavelet representation of hardcore bosons
Etienne Granet
We consider the 1D Tonks-Girardeau gas with a space-dependent potential out of equilibrium. We derive the exact dynamics of the system when divided into boxes and decomposed in…
Volume-law to area-law entanglement transition in a non-unitary periodic Gaussian circuit
Etienne Granet, Carolyn Zhang, Henrik Dreyer
We consider Gaussian quantum circuits that alternate unitary gates and post-selected weak measurements, with spatial translation symmetry and time periodicity. We show analytically…
