Data-Driven Learnability Transition of Measurement-Induced Entanglement
Dongheng Qian, Jing Wang
Measurement-induced entanglement (MIE) captures how local measurements generate long-range quantum correlations and drive dynamical phase transitions in many-body systems. Yet esti…
Quantum Non-Local Nonstabilizerness
Dongheng Qian, Jing Wang
Quantum entanglement and quantum nonstabilizerness are fundamental resources that characterize distinct aspects of a quantum state: entanglement reflects non-local correlations, wh…
Intrinsic Quantum Mpemba Effect in Markovian Systems and Quantum Circuits
Dongheng Qian, Huan Wang, Jing Wang
The quantum Mpemba effect (QME) describes the counterintuitive phenomenon in which a system farther from equilibrium reaches steady state faster than one closer to equilibrium. How…
Coherent Information Phase Transition in a Noisy Quantum Circuit
Dongheng Qian, Jing Wang
Coherent information quantifies the transmittable quantum information through a channel and is directly linked to the channel's quantum capacity. In a monitored quantum circuit, re…
Protect Measurement-Induced Phase Transition from Noise
Dongheng Qian, Jing Wang
Scrambling dynamics induced by random unitary gates can protect information from low-rate measurements, which underpins the phenomenon known as the measurement-induced phase transi…
Steering-induced phase transition in measurement-only quantum circuits
Dongheng Qian, Jing Wang
Competing measurements alone can give rise to distinct phases characterized by entanglement entropy$\unicode{x2013}$such as the volume law phase, symmetry-breaking (SB) phase, and…
