Mathieu Control of the Effective Coupling in Superconducting Qubits
Yi-Han Yu, Xin-Yi Li, Kai Xu +1
A common challenge in superconducting quantum circuits is the trade-off between strong coupling and computational subspace integrity. We present Mathieu control, which uses a non-r…

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…
