Continuous-wave AC magnetometry up to hundreds of megahertz using nitrogen-vacancy centers under a strong transverse magnetic field
Ryusei Okaniwa, Rui Suzuki, Yuichiro Matsuzaki +2
Nitrogen-vacancy (NV) centers in diamond are promising quantum sensors for AC magnetic fields. However, conventional dynamical-decoupling-based magnetometry becomes technically dem…
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
Quantum sensing estimates a physical parameter encoded in the state of a probe; with independent spin probes the precision follows the standard quantum limit. Studies of sensing pr…
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…
Hybrid-spin decoupling for noise-resilient DC quantum sensing
So Chigusa, Masashi Hazumi, Ernst David Herbschleb +3
The excellent sensitivities of quantum sensors are a double-edged sword: minuscule quantities can be observed, but any undesired signal acts as noise. This is challenging when dete…
Mitigating Detuning-Induced Systematic Errors in Entanglement-Enhanced Metrology
Shingo Kukita, Yuichiro Matsuzaki
Quantum sensing leverages non-classical resources to enhance precision. In particular, Greenberger-Horne-Zeilinger (GHZ) states can, in principle, attain the Heisenberg limit that…
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…
