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…
Spatially Resolved Optical Responses of a High-Kinetic-Inductance Microwave Resonator
R. Hirotsuru, H. Kurokawa, K. Takaki +2
Understanding the optical response of a high-kinetic-inductance microwave resonator is crucial for applications ranging from single-photon detection to quantum transduction between…
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…
