Experimental Realization of a C-Shunt Flux-Qubit Coupler for Controlled-Z Gates between Transmons
Weiping Yuan, Silu Zhao, Li Li +16
Fast entangling gates and low-interaction idling require distinct operating conditions in superconducting quantum processors. We experimentally realize a transmon-C-shunt-transmon…
Programmable spectral symmetries in an anisotropic quantum Rabi simulator
Jia-Cheng Song, Yu Liu, Ming-Chuan Wang +28
The quantum Rabi model captures fundamental aspects of light--matter interaction, where symmetry dictates both spectra and dynamics. Over the past years, experiments have explored…
