Coherent Dark State Formation of a Lead-Vacancy Spin Qubit in Diamond
Yiyang Chen, Koyo Hirai, Tzyy Zheng Neo +7
A lead-vacancy (PbV) center in diamond exhibits coherent emission above the liquid helium temperature, making it highly attractive for quantum network applications. Here, we report…
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…
Transform-Limited Photon Emission From a Lead-Vacancy Center in Diamond Above 10 K
Peng Wang, Lev Kazak, Katharina Senkalla +9
Transform-limited photon emission from quantum emitters is essential for high-fidelity entanglement generation. In this study, we report the coherent optical property of a single n…
Coherent Electric-Field Control of Orbital state in a Neutral Nitrogen-Vacancy Center
Hodaka Kurokawa, Keidai Wakamatsu, Shintaro Nakazato +4
The coherent control of the orbital state is crucial for color centers in diamonds for realizing extremely low-power manipulation. Here, we propose the neutrally charged nitrogen-v…
