We present a scalable scheme for executing the error-correction cycle of a monolithic surface-code fabric composed of fast-flux-tuneable transmon qubits with nearest-neighbor coupl…
Current-phase relation of ballistic graphene Josephson junctions
Gaurav Nanda, Juan Luis Aguilera-Servin, Péter Rakyta +7
The current-phase relation (CPR) of a Josephson junction (JJ) determines how the supercurrent evolves with the superconducting phase difference across the junction. Knowledge of th…
