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…
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…
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…
Development of a high-power ultraviolet laser system and observation of fast coherent Rydberg excitation of ytterbium
Yuma Nakamura, Naoya Ozawa, Toshi Kusano +5
We present the development of a high-power ultraviolet laser system operating at a wavelength of 325 nm for Rydberg excitation from the state of ytterbium. Utili…
A hybrid atom tweezer array of nuclear spin and optical clock qubits
Yuma Nakamura, Toshi Kusano, Rei Yokoyama +6
While data qubits with a long coherence time are essential for the storage of quantum information, ancilla qubits are pivotal in quantum error correction (QEC) for fault-tolerant q…
