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…
Many-body delocalization with a two-dimensional 70-qubit superconducting quantum simulator
Tian-Ming Li, Zheng-Hang Sun, Yun-Hao Shi +35
Quantum many-body systems with sufficiently strong disorder can exhibit a non-equilibrium phenomenon, known as the many-body localization (MBL), which is distinct from conventional…
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…
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…
High-precision pulse calibration of tunable couplers for high-fidelity two-qubit gates in superconducting quantum processors
Tian-Ming Li, Jia-Chi Zhang, Bing-Jie Chen +23
For superconducting quantum processors, stable high-fidelity two-qubit operations depend on precise flux control of the tunable coupler. However, the pulse distortion poses a signi…
