Developmental platform demonstrates hybrid coupling between levitated spheres and superconducting qubits, suggesting expanded applications in gravimetry and dark matter detection.
Sensing with hybrid systems formed of superconducting levitated spheres and qubitsLevitated superconducting spheres at ultra-low temperatures have very long relaxation times 4 , which can be leveraged in quantum sensing practical applications (e.g.gravimetry) in addition to fundamental application (e.g.dark matter detection 5 ).Coupling a levitated sphere to a superconducting qubit enables new measurement protocols. Qubit Levitated sphereAdvanced design and material characterization are critical to this new platform, leveraging SQMS expertise and research advances in other projects.
