Entanglement phase transitions in measurement-only dynamics

M Ippoliti, MJ Gullans, S Gopalakrishnan, DA Huse… - Physical Review X, 2021 - APS
Unitary circuits subject to repeated projective measurements can undergo an entanglement
phase transition (EPT) as a function of the measurement rate. This transition is generally …

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 …

Theory of free fermions under random projective measurements

I Poboiko, P Pöpperl, IV Gornyi, AD Mirlin - Physical Review X, 2023 - APS
We develop an analytical approach to the study of one-dimensional free fermions subject to
random projective measurements of local site occupation numbers, based on the Keldysh …

Robust teleportation of a surface code and cascade of topological quantum phase transitions

F Eckstein, B Han, S Trebst, GY Zhu - PRX Quantum, 2024 - APS
Teleportation is a facet where quantum measurements can act as a powerful resource in

Floquet codes without parent subsystem codes

M Davydova, N Tantivasadakarn, S Balasubramanian - PRX Quantum, 2023 - APS
We propose a new class of error-correcting dynamic codes in two and three dimensions that
has no explicit connection to any parent subsystem code. The two-dimensional code, which …

Fractal, logarithmic, and volume-law entangled nonthermal steady states via spacetime duality

M Ippoliti, T Rakovszky, V Khemani - Physical Review X, 2022 - APS
The extension of many-body quantum dynamics to the nonunitary domain has led to a series
of exciting developments, including new out-of-equilibrium entanglement phases and phase …

Nishimori's cat: stable long-range entanglement from finite-depth unitaries and weak measurements

GY Zhu, N Tantivasadakarn, A Vishwanath, S Trebst… - Physical Review Letters, 2023 - APS
In the field of monitored quantum circuits, it has remained an open question whether finite-
time protocols for preparing long-range entangled states lead to phases of matter that are …

Controlling entanglement at absorbing state phase transitions in random circuits

P Sierant, X Turkeshi - Physical Review Letters, 2023 - APS
Many-body unitary dynamics interspersed with repeated measurements display a rich
