Abstract
In a superconducting nanowire of an appropriate material and geometry, the impedance at microwave frequencies can be dominated by kinetic inductance, which arises from the kinetic energy of the moving charge carriers that comprise a current. Kinetic inductance is inversely proportional to the Cooper pair density, which varies as a function of temperature, current, and magnetic field. Kinetic inductance provides a nondissipative nonlinear impedance that can serve as the basis for a variety of useful devices. These devices include single-photon detectors such as the microwave kinetic inductance detector (MKID) and the superconducting nanowire single-photon detector (SNSPD). They also include microwave devices that are relevant to scaling up superconducting quantum computing platforms such as parametric amplifiers, tunable resonators and couplers, and even qubits. This talk will review the physics of kinetic inductance in superconducting nanowires and discuss some of their established and emerging device applications, with a particular focus on applications in the growing quantum information ecosystem.
