Quantum information phases in space-time: measurement-induced entanglement and teleportation on a noisy quantum processor — •Vedika Khemani — Stanford University, USA

I will discuss the dynamics of monitored systems combining the ingredients of unitary evolution, measurements, and adaptive classical control. I will present various novel dynamical phases and phase transitions that arise in these systems, ranging from entanglement and teleportation phase transitions to "learnability" transitions in the ability to reconstruct quantum information from measurements. I will also discuss experimental realizations of these phenomena in noisy quantum processors.

Keywords: quantum dynamics; entanglement dynamics; measurement induced phase transitions
