Enhanced quantum sensing with room-temperature solid-state masers

Robust quantum control for the manipulation of solid-state spins

“…Furthermore, this presented approach is fully compatible with other quantum systems, such as superconducting qubits, trapped ions and Rydberg atoms. It would also be an essential technique to be added to the toolbox for improving the sensitivity of solid-state ensemble spin sensors, such as NV centers in diamond, V Si in SiC and organic spin sensors [34], of which the sensitivities are limited by the inhomogeneous broadening [35] or the dynamic biological environment [36]. )UHTXHQF\*+] the Overhauser field (caused by interactions with nuclear spin bath) and the distortion of microwave amplitudes (caused by limited bandwidth), we designed and fabricated an ultra-broadband CPW structure with a bandwidth up to 6 GHz [37].…”
