Universality of the cross entropy in symmetric monitored quantum circuits
Maria Tikhanovskaya, Ali Lavasani, Matthew P. A. Fisher +1
The linear cross-entropy (LXE) has been recently proposed as a scalable probe of the measurement-driven phase transition between volume- and area-law-entangled phases of pure-state…
Continuous symmetry breaking in adaptive quantum dynamics
Jacob Hauser, Yaodong Li, Sagar Vijay +1
Adaptive quantum circuits, in which unitary operations, measurements, and feedback are used to steer quantum many-body systems, provide an exciting opportunity to generate new dyna…
Quantum Coding Transitions in the Presence of Boundary Dissipation
Izabella Lovas, Utkarsh Agrawal, Sagar Vijay
We investigate phase transitions in the encoding of quantum information in a quantum many-body system due to the competing effects of unitary scrambling and boundary dissipation. S…
Mixed-state long-range order and criticality from measurement and feedback
Tsung-Cheng Lu, Zhehao Zhang, Sagar Vijay +1
We propose a general framework for using local measurements, local unitaries, and non-local classical communication to construct quantum channels which can efficiently prepare mixe…
