Onset of scrambling as a dynamical transition in tunable-range quantum circuits
Sridevi Kuriyattil, Tomohiro Hashizume, Gregory Bentsen +1
In a fast scrambling many-body quantum system, information is spread and entanglement is built up on a timescale that grows logarithmically with the system size. This is of fundame…

Non-Markovian Quantum Dynamics in Strongly Coupled Multimode Cavities Conditioned on Continuous Measurement
Valentin Link, Kai Müller, Rosaria G. Lena +4
An important challenge in non-Markovian open quantum systems is to understand what information we gain from continuous measurement of an output field. For example, atoms in multimo…
Measurement-induced phase transitions in sparse nonlocal scramblers
Tomohiro Hashizume, Gregory Bentsen, Andrew J. Daley
Measurement-induced phase transitions arise due to a competition between the scrambling of quantum information in a many-body system and local measurements. In this work we investi…
