Spin-Cat Qubit with Biased Noise in an Optical Tweezer Array

Toshi Kusano, Kosuke Shibata, Chih-Han Yeh +8

Bias-tailored quantum error correcting codes (QECCs) offer a higher error threshold than standard QECCs and have the potential to achieve lower logical errors with less space overh…

Observation of slow relaxation due to Hilbert space fragmentation in strongly interacting Bose-Hubbard chains

Kantaro Honda, Yosuke Takasu, Shimpei Goto +4

While isolated quantum systems generally thermalize after long-time evolution, there are several exceptions defying thermalization. A notable mechanism of such nonergodicity is the…
