Detecting dark matter using optically trapped Rydberg atom tweezer arrays
So Chigusa, Taiyo Kasamaki, Toshi Kusano +6
A new scheme for detecting wave-like dark matter (DM) using Rydberg atoms is proposed. Recent advances in trapping and manipulating Rydberg atoms make it possible to use Rydberg at…
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…
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…
Light Dark Matter Detection with Sub-eV Transition-Edge Sensors
Muping Chen, Volodymyr Takhistov, Kazunori Nakayama +1
We present a comprehensive analysis of high-resolution transition-edge sensors (TESs) as a quantum sensing platform for detecting dark matter (DM). Operating near the thermodynamic…
Nuclear Spin Metrology with Nitrogen Vacancy Center in Diamond for Axion Dark Matter Detection
So Chigusa, Masashi Hazumi, Ernst David Herbschleb +3
We present a method to directly detect the axion dark matter using nitrogen vacancy centers in diamonds. In particular, we use metrology leveraging the nuclear spin of nitrogen to…
