Measurement Induced Entanglement Transitions in Quantum Circuits with Decoherence - Ehud Altman

Explore measurement-induced entanglement transitions in quantum circuits with decoherence in this 44-minute conference talk by Ehud Altman from the Kavli Institute for Theoretical Physics. Delve into the comparison between classical and quantum thermalization, and examine hybrid quantum circuits exhibiting measurement-induced phase transitions. Learn techniques for characterizing trajectory ensembles and discover the intrinsic dynamical symmetry. Investigate the mapping to an effective classical "spin model" and understand the logarithmic negativity as a measure of tri-partite entanglement. Analyze the Page transition in negativity for random and thermal states, as well as in random unitary circuits. Examine numerical simulations of Clifford circuits and explore the infinite bath volume law phase. Gain insights into non-equilibrium many-body physics and universal aspects of far-from-equilibrium systems at the intersection of statistical physics, AMO, condensed matter, and high-energy physics.
