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 …

Measurement-altered Ising quantum criticality

S Murciano, P Sala, Y Liu, RSK Mong, J Alicea - Physical Review X, 2023 - APS
Quantum critical systems constitute appealing platforms for exploring novel measurement-
induced phenomena due to their innate sensitivity to perturbations. We study the impact of …

EJ Gustafson, ACY Li, A Khan, J Kim… - Quantum, 2023 - quantum-journal.org
Quantum many-body scar states are highly excited eigenstates of many-body systems that
exhibit atypical entanglement and correlation properties relative to typical eigenstates at the …

Dynamical entanglement transition in the probabilistic control of chaos

T Iadecola, S Ganeshan, JH Pixley… - arXiv preprint arXiv …, 2022 - arxiv.org
We uncover a dynamical entanglement transition in a monitored quantum system that is
heralded by a local order parameter. Classically, chaotic systems can be stochastically …
