Absorption-emission quantum repeater using diamond quantum memories
Taichi Fujiwara, Yuhei Sekiguchi, Raustin Reyes +3
Quantum repeaters are essential for overcoming the exponential photon loss that limits entanglement generation over long distances in quantum networks. An absorption-emission-based…
Scalable on-chip integration of diamond color centers for cryogenic quantum photonics
H. Kurokawa, K. Sato, M. Kamata +16
Chip integration of quantum emitters is a crucial milestone for scalable quantum photonic information processing. Among optically active defect centers for quantum photonics, diamo…
Modular interface for efficient optical readout of diamond quantum memory at cryogenic temperatures via single-mode optical fibers
Akira Kamimaki, Yuhei Sekiguchi, Daisuke Ito +4
Efficient quantum devices across various physical systems have been rapidly developed for entanglement-based quantum repeaters and spin-photon conversion; however, far less attenti…
Robust transfer of a quantum state from an absorbed photon into a diamond spin
Daisuke Ito, Yuhei Sekiguchi, Raustin Reyes +4
Conversion of a quantum state from a flying qubit to a memory qubit is crucial for distributed quantum computing. However, this requires precise spatiotemporal or frequency/phase a…
Quantum Orbital-State Control of a Neutral Nitrogen-Vacancy Center at Millikelvin Temperatures
Hodaka Kurokawa, Shintaro Nakazato, Toshiharu Makino +4
A neutral nitrogen-vacancy center (NV) is promising for realizing strong coupling with a single microwave photon due to its large electric field sensitivity, although it is sus…
