Revealing Entanglement-Growth Mechanisms through the Magic Barrier
Lv Zhang, Shi-Xin Zhang, Heng Fan +1
Quantum entanglement and magic are complementary resources underlying quantum computational advantage, yet their dynamical relation in many-body systems remains poorly understood.…
Microwave Engineering of Tunable Spin Interactions with Superconducting Qubits
Kui Zhao, Ziting Wang, Yu Liu +24
Quantum simulation has emerged as a powerful framework for investigating complex many - body phenomena. A key requirement for emulating these dynamics is the realization of fully c…
Tuning the Quantum Mpemba Effect in Isolated System by Initial State Engineering
Yihan Yu, Tianren Jin, Lv Zhang +2
We investigate the quantum Mpemba effect (QME) in isolated, non-integrable quantum systems, where relaxation dynamics depend on structure of the initial states. By analyzing the di…
Prethermalization by Random Multipolar Driving on a 78-Qubit Superconducting Processor
Zheng-He Liu, Yu Liu, Gui-Han Liang +43
Time-dependent drives hold the promise of realizing non-equilibrium many-body phenomena that are absent in undriven systems. Yet, drive-induced heating normally destabilizes the sy…
Quantum Avalanches in -preserving Interacting Ising Majorana Chain
Lv Zhang, Kai Xu, Heng Fan
Recent numerical works have revealed the instability of many-body localized (MBL) phase in disordered quantum many-body systems with finite system sizes and over finite timescales.…
