Abstract: A superconducting flux qubit readout system may include an input-output system connected to at least one shift register, the shift register comprising a first set, a second set, and a third set of shift register stages arranged in series, the first set of shift register stages coupled to a first set of qubits by a first plurality of latches, and the second set of shift register stages coupled to a second set of qubits by a second plurality of latches. Reading out states of a first set of qubits may include: shifting qubit state information to first holding latches communicatively coupled to a shift register; obtaining, by each shift register stage of the first set of shift register stages, state information from the first holding latches; and, propagating information along the shift register.
