Analysis of Superradiance-Based Quantum Metrology under Independent Markovian Pure Dephasing
Yasunari Sakuma, Yuichiro Matsuzaki, Hoi-Kwan Lau +1
Recently, a DC magnetometry protocol utilizing -spin-ensemble superradiance was proposed. This method physically amplifies the acquired signal, suppressing estimation errors fro…
Suppressing Detuning-Induced Bias in Ramsey Magnetometry with Composite Pulses
Shingo Kukita, Kento Nawata, Yuichiro Matsuzaki
The paper proposes a composite‑pulse technique for single‑qubit Ramsey magnetometry that cancels first‑order bias caused by unknown detuning, improving the accuracy of DC magnetic…
Broadband AC Magnetic Field Sensing via Continuous wave optically detected magnetic resonance with NV Centers in diamond
Ryohei Dokai, Ryusei Okaniwa, Miku Ishizaki +2
The nitrogen-vacancy (NV) center in diamond has attracted considerable attention as a highly sensitive quantum sensor that can operate at room temperature. In particular, continuou…
Enhanced Temperature Sensitivity in Ensemble NV Centers through Improved Optically Detected Magnetic Resonance Spectral Modeling
Yuki S. Kato, Shingo Sotoma, Keisuke Fujita +5
Nitrogen-vacancy (NV) center ensembles provide a powerful platform for high-precision temperature sensing, with ongoing efforts to further enhance their measurement performance. In…
Directional search for light dark matter with quantum sensors
Hajime Fukuda, Yuichiro Matsuzaki, Thanaporn Sichanugrist
The presence of dark matter (DM) stands as one of the most compelling indications of new physics in particle physics. Typically, the detection of wave-like DM involves quantum sens…
Entanglement-enhanced AC magnetometry in the presence of Markovian noises
Thanaporn Sichanugrist, Hajime Fukuda, Takeo Moroi +5
Entanglement is a resource to improve the sensitivity of quantum sensors. In an ideal case, using an entangled state as a probe to detect target fields, we can beat the standard qu…
