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…
Exploring Hilbert-Space Fragmentation on a Superconducting Processor
Yong-Yi Wang, Yun-Hao Shi, Zheng-Hang Sun +22
Isolated interacting quantum systems generally thermalize, yet there are several examples for the breakdown of ergodicity, such as many-body localization and quantum scars. Recentl…
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…
Microwave-activated high-fidelity three-qubit gate scheme for fixed-frequency superconducting qubits
Kui Zhao, Wei-Guo Ma, Ziting Wang +5
Scalable superconducting quantum processors require balancing critical constraints in coherence, control complexity, and spectral crowding. Fixed-frequency architectures suppress f…
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…
