Observation and Modulation of the Quantum Mpemba Effect on a Superconducting Quantum Processor
Yueshan Xu, Cai-Ping Fang, Bing-Jie Chen +33
In non-equilibrium quantum systems, the quantum Mpemba effect (QME) emerges as a counterintuitive phenomenon: systems exhibiting greater initial symmetry breaking restore symmetry…
Observing Quantum Correlation Dynamics in Tunable Superconducting Bose-Hubbard Simulators
Z. T. Wang, Si-Yun Zhou, Yun-Hao Shi +18
The dynamics of quantum correlations are central to understanding many physical properties of quantum systems. Here we experimentally study the correlation dynamics via two-particl…
Observation of Inelastic Meson Scattering in a Floquet System using a Digital Quantum Simulator
Ziting Wang, Zi-Yong Ge, Yun-Hao Shi +19
Lattice gauge theories provide a non-perturbative framework for understanding confinement and hadronic physics, but their real-time dynamics remain challenging for classical comput…
Non-Equilibrium Criticality-Enhanced Quantum Sensing with Superconducting Qubits
Hao Li, Yaoling Yang, Yun-Hao Shi +24
Exploiting quantum features allows for estimating external parameters with precisions well beyond the capacity of classical sensors, a phenomenon known as quantum-enhanced precisio…
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…
Direct Implementation of High-Fidelity Three-Qubit Gates for Superconducting Processor with Tunable Couplers
Hao-Tian Liu, Bing-Jie Chen, Jia-Chi Zhang +18
Three-qubit gates can be constructed using combinations of single-qubit and two-qubit gates, making their independent realization unnecessary. However, direct implementation of thr…
