Minimally Destructive Fast Imaging of Single Atoms in an Optical Tweezer Array with Coherent Excitation
Rei Yokoyama, Takumi Kashimoto, Kosuke Shibata +8
Ultracold neutral atoms in an optical lattice and an optical tweezer array offer highly-controllable quantum many-body systems, utilized for various quantum science and technology…
Gain engineering and atom lasing in a topological edge state in synthetic dimensions
Takuto Tsuno, Shintaro Taie, Yosuke Takasu +3
Recent advances in quantum technology have highlighted the importance of controlling quantum states, especially in open quantum systems, where the system interacts with the environ…
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…
Plane-selective manipulations of nuclear spin qubits in a three-dimensional optical tweezer array
Toshi Kusano, Yuma Nakamura, Rei Yokoyama +5
One of the central challenges for a practical fault-tolerant quantum computer is scalability. A three-dimensional structure of optical tweezer arrays offers the potential for scali…
Exploring the Strongly-Interacting Regime of Effective Multi-Body Interactions in a Trapped Ultracold Atom System
Kantaro Honda, Yosuke Takasu, Yuki Haruna +2
A two-body interaction or force between quantum particles is ubiquitous in nature, and the microscopic description in terms of the bare two-body interaction is the basis for quanti…
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…
