The Josephson junction is the information-processing heart of the superconducting qubit. In classical information processing, data comes in bits that are either 0s or 1s. In quantum information ...

Fluxonium is a type of superconducting qubit made up of a capacitor and Josephson junction; unlike transmon qubits, however, fluxonium also includes a large "superinductor," which by design helps ...

But quantum computing—performing operations by employing quantum states such as nuclear spins, Josephson-junction arrays ... be stored in a pair of spatially separated MZMs—a Majorana qubit—which is ...

Single- and two-qubit gates and frequency-multiplexed qubit readouts ... A parametric amplifier using a Josephson junction (a circuit element in which two superconductors are weakly coupled via an ...
