Nuclear Magnetic Resonance model of an entangled sensor under noise
Le Bin Ho, Yuichiro Matsuzaki, Masayuki Matsuzaki +1
Entangled sensors have been attracting a lot of attention recently because they can achieve the sensitivity beyond that of the classical sensors. To exploit entanglement as a resou…
Single Spin Detection with Entangled States
Hideaki Hakoshima, Yuichiro Matsuzaki
Single spin detection is one of the important tasks in the field of quantum metrology. Many experiments about the single spin detection has been performed. However, due to the weak…
Variational-State Quantum Metrology
Bálint Koczor, Suguru Endo, Tyson Jones +2
Quantum technologies exploit entanglement to enhance various tasks beyond their classical limits including computation, communication and measurements. Quantum metrology aims to in…
Experimental demonstration of secure quantum remote sensing
Peng Yin, Yuki Takeuchi, Wen-Hao Zhang +10
Quantum metrology aims to enhance the precision of various measurement tasks by taking advantages of quantum properties. In many scenarios, precision is not the sole target; the ac…
Experimental and theoretical analysis of noise strength and environmental correlation time for ensembles of nitrogen-vacancy centers in diamond
Kan Hayashi, Yuichiro Matsuzaki, Takaki Ashida +8
We experimentally and theoretically investigate the Hahn echo decay curve for nitrogen vacancy centers in diamond with different spin concentrations. The Hahn echo results show a n…
Nuclear magnetic resonance spectroscopy with a superconducting flux qubit
Koichiro Miyanishi, Yuichiro Matsuzaki, Hiraku Toida +4
We theoretically analyze the performance of the nuclear magnetic resonance (NMR) spectroscopy with a superconducting flux qubit (FQ). Such NMR with the FQ is attractive because of…
