Dear all,

Next Monday, April 3, we will have an virtual quantum matter seminar by Austin Minnich from Caltech. Austin will talk about an experimental realization of the measurement-induced entanglement phase transition.

The information is as follows:

Monday, April 3, 10:00am

As usual, students and postdocs are invited to stay after the talk to chat with Austin. His title and abstract are below.

I look forward to seeing you there.

Title: Experimental Realization of a Measurement-Induced Entanglement Phase Transition on a Superconducting Quantum Processor with Mid-Circuit Readout

Abstract: The usual picture of quantum dynamics is that of an isolated system evolving under unitary interactions. Systems in which non-unitary measurements are interspersed among the unitary interactions are now of great interest due to the novel phenomena that occur, including phase transitions of the entanglement properties depending on the measurement rate. These systems remain challenging to investigate on near-term quantum hardware owing to the need for repeated high-fidelity mid-circuit measurements, a capability that has only recently become available.  We report the realization of such a measurement-induced entanglement phase transition on up to 14 superconducting qubits with mid-circuit readout capability. We observe a distinct change in entanglement properties of quantum phases by varying the rate of the measurements. We further demonstrate phenomenological critical behavior by performing a data collapse of the measured entanglement entropy. Our work paves the way for the use of mid-circuit measurement as a powerful resource for quantum simulation on near-term quantum computers.
