  • Quantum power sensor and method of measuring power in transmission lines
    Patent number: 11112442
    Abstract: A quantum power sensor has a two-level quantum system strongly coupled to a transmission line that supports a propagating wave. A method of measuring power in a transmission line includes coupling a two-level quantum system to the transmission line; and determining the coupling and the Rabi frequency of the two-level system.
