Abstract:
1. A superconducting readout system comprising: a computation qubit; a measurement device to measure a state of the computation qubit; a first latch qubit comprising a qubit loop formed by a loop of superconducting material and a compound Josephson junction that interrupts the qubit loop, wherein the compound Josephson junction is formed by a closed loop of superconducting material that is interrupted by at least two Josephson junctions; and a first clock signal input structure configured to communicatively couple clock signals to the compound Josephson junction of the first latch qubit; wherein at least one of the computation qubit and the measurement device is configured to communicatively couple to the first latch qubit such that the first latch qubit mediates a communicative coupling between the computation qubit and the measurement device.
