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…

Giant-atom quantum acoustodynamics in hybrid superconducting-phononic integrated circuits

Lintao Xiao, Bo Zhang, Yu Zeng +11

We demonstrate a giant atom by coupling a superconducting transmon qubit to a lithium niobate phononic waveguide at two points separated by about 600 acoustic wavelengths, with a p…
