Electron paramagnetic resonance spectroscopy using a single artificial atom
Hiraku Toida, Yuichiro Matsuzaki, Kosuke Kakuyanagi +4
Electron paramagnetic resonance (EPR) spectroscopy is an important technology in physics, chemistry, materials science, and biology. Sensitive detection with a small sample volume…
Electron Paramagnetic Resonance Spectroscopy of Er:YSiO Using Josephson Bifurcation Amplifier: Observation of Hyperfine and Quadrupole Structures
Rangga P. Budoyo, Kosuke Kakuyanagi, Hiraku Toida +4
We performed magnetic field and frequency tunable electron paramagnetic resonance spectroscopy of an Er doped YSiO crystal by observing the change in flux induced on…
Quantum metrology beyond the classical limit under the effect of dephasing
Yuichiro Matsuzaki, Simon Benjamin, Shojun Nakayama +2
Quantum sensors have the potential to outperform their classical counterparts. For classical sensing, the uncertainty of the estimation of the target fields scales inversely with t…
Single spin detection with an ensemble of probe spins
Syuhei Uesugi, Yuichiro Matsuzaki, Suguru Endo +2
Single spin detection is a key objective in the field of metrology. There have been many experimental and theoretical investigations for the spin detection based on the use of prob…
Vector magnetic field sensing via multi-frequency control of nitrogen-vacancy centers in diamond
Sayaka Kitazawa, Yuichiro Matsuzaki, Saijo Soya +3
An ensemble of nitrogen-vacancy (NV) centers in diamond is an attractive device to detect small magnetic fields. In particular, by exploiting the fact that the NV center can be ali…
Dynamics of an ultra-strongly-coupled system interacting with a driven nonlinear resonator
Suguru Endo, Yuichiro Matsuzaki, Kosuke Kakuyanagi +3
In the ultra-strong coupling regime of a light-matter system, the ground state exhibits non-trivial entanglement between the atom and photons. For the purposes of exploring the mea…
