Universality in driven open quantum matter

LM Sieberer, M Buchhold, J Marino, S Diehl - arXiv preprint arXiv …, 2023 - arxiv.org
Universality is a powerful concept, which enables making qualitative and quantitative
predictions in systems with extensively many degrees of freedom. It finds realizations in …

Probing postmeasurement entanglement without postselection

Majorana loop models for measurement-only quantum circuits

K Klocke, M Buchhold - Physical Review X, 2023 - APS
Projective measurements in random quantum circuits lead to a rich breadth of entanglement
phases and extend the realm of nonunitary quantum dynamics. Here, we explore the …

Characterizing a non-equilibrium phase transition on a quantum computer

Entanglement and absorbing-state transitions in interactive quantum dynamics

N O'Dea, A Morningstar, S Gopalakrishnan, V Khemani - Physical Review B, 2024 - APS
Nascent quantum computers motivate the exploration of quantum many-body systems in
nontraditional scenarios. For example, it has become natural to explore the dynamics of …

Absence of measurement-induced entanglement transition due to feedback-induced skin effect

Entanglement Phase Transition Due to Reciprocity Breaking without Measurement or Postselection

G Lee, T Jin, YX Wang, A McDonald, A Clerk - PRX Quantum, 2024 - APS
Despite its fully unitary dynamics, the bosonic Kitaev chain (BKC) displays key hallmarks of
non-Hermitian physics, including nonreciprocal transport and the non-Hermitian skin effect …

Measurement-induced phase transition for free fermions above one dimension

I Poboiko, IV Gornyi, AD Mirlin - Physical Review Letters, 2024 - APS
A theory of the measurement-induced entanglement phase transition for free-fermion
