Qiskit Seminar Series Episode 118 with Austin Minnich Experimental Realization of a Measurement-Induced Entanglement Phase Transition on a Superconducting Quantum Processor with Mid-Circuit Readout Paper: https://arxiv.org/abs/2203.04338 Your formal invite to weekly Qiskit videos ► https://ibm.biz/q-subscribe Speaker: Austin Minnich Host: Derek Wang 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.
