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…
Beyond Qubits: Multilevel Quantum Sensing for Dark Matter
Xiaolin Ma, Volodymyr Takhistov, Norikazu Mizuochi +1
Quantum sensing with qubits has advanced fundamental physics searches, but higher dimensional systems offer untapped potential. We present a universal qutrit framework that yields…
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…
Light Dark Matter Search with Nitrogen-Vacancy Centers in Diamonds
So Chigusa, Masashi Hazumi, Ernst David Herbschleb +2
We propose new ideas to directly search for light dark matter, such as the axion or the dark photon, by using magnetometry with nitrogen-vacancy centers in diamonds. If the dark ma…
Low-frequency quantum sensing
E. D. Herbschleb, I. Ohki, K. Morita +5
Exquisite sensitivities are a prominent advantage of quantum sensors. Ramsey sequences allow precise measurement of direct current fields, while Hahn-echo-like sequences measure al…
Shallow NV centers augmented by exploiting n-type diamond
A. Watanabe, T. Nishikawa, H. Kato +6
Creation of nitrogen-vacancy (NV) centers at the nanoscale surface region in diamond, while retaining their excellent spin and optical properties, is essential for applications in…
Direct Imaging of Coherent Quantum Transport in Graphene Heterojunctions
E. D. Herbschleb, R. K. Puddy, P. Marconcini +5
We fabricate a graphene p-n-p heterojunction and exploit the coherence of weakly-confined Dirac quasiparticles to resolve the underlying scattering potential using low temperature…
Reading and writing charge on graphene devices
M. R. Connolly, E. D. Herbschleb, R. K. Puddy +5
We use a combination of charge writing and scanning gate microscopy to map and modify the local charge neutrality point of graphene field-effect devices. We give a demonstration of…
