Neural-Network Decoders for Measurement Induced Phase Transitions

Understand

Open quantum systems have been shown to host a plethora of exotic dynamical phases.

• Measurement-induced entanglement phase transitions in monitored quantum systems are a striking example of this phenomena.
• However, naive realizations of such phase transitions requires an exponential number of repetitions of the experiment which is practically unfeasible on large systems.
• Recently, it has been proposed that these phase transitions can be probed locally via entangling reference qubits and studying their purification dynamics.
