Optimization temperature sensitivity using the optically detected magnetic resonance spectrum of a nitrogen-vacancy center ensemble
Kan Hayashi, Yuichiro Matsuzaki, Takashi Taniguchi +8
Temperature sensing with nitrogen vacancy (NV) centers using quantum techniques is very promising and further development is expected. Recently, the optically detected magnetic res…
Optically detected magnetic resonance of high-density ensemble of NV centers in diamond
Yuichiro Matsuzaki, Hiroki Morishita, Takaaki Shimooka +7
Optically detected magnetic resonance (ODMR) is a way to characterize the NV centers. Recently, a remarkably sharp dip was observed in the ODMR with a high-density ensemble of NV c…
Improving the coherence time of a quantum system via a coupling with an unstable system
Yuichiro Matsuzaki, Xiaobo Zhu, Kosuke Kakuyanagi +8
Here, we propose a counter-intuitive use of a hybrid system where the coherence time of a quantum system is actually improved via a coupling with an unstable system. If we couple a…
Towards Realizing a Quantum Memory for a Superconducting Qubit: Storage and Retrieval of quantum states
Shiro Saito, Xiaobo Zhu, Robert Amsüss +7
We have built a hybrid system composed of a superconducting flux qubit (the processor) and an ensemble of nitrogen-vacancy centers in diamond (the memory) that can be directly coup…
