Critical properties of the measurement-induced transition in random quantum circuits
Aidan Zabalo, Michael J. Gullans, Justin H. Wilson +3
We numerically study the measurement-driven quantum phase transition of Haar-random quantum circuits in dimensions. By analyzing the tripartite mutual information we are able…
Scalable probes of measurement-induced criticality
Michael J. Gullans, David A. Huse
We uncover a local order parameter for measurement-induced phase transitions: the average entropy of a single reference qubit initially entangled with the system. Using this order…
Dynamical purification phase transitions induced by quantum measurements
Michael J. Gullans, David A. Huse
Continuously monitoring the environment of a quantum many-body system reduces the entropy of (purifies) the reduced density matrix of the system, conditional on the outcomes of the…
Observation of chiral photocurrent transport in the quantum Hall regime in graphene
Olivier Gazzano, Bin Cao, Jiuning Hu +6
Optical excitation provides a powerful tool to investigate non-equilibrium physics in quantum Hall systems. Moreover, the length scale associated with photo-excited charge carries…
Localization as an entanglement phase transition in boundary-driven Anderson models
Michael J. Gullans, David A. Huse
The Anderson localization transition is one of the most well studied examples of a zero temperature quantum phase transition. On the other hand, many open questions remain about th…
