Summary:Systems and methods are provided for readout of a qubit. A readout resonator is coupled to a transmission line and a compound Josephson junction coupler couples the qubit to the readout resonator. A coupling controller controls the coupling strength of the compound Josephson junction coupler such that a coupling between the qubit and the readout resonator is a first value when a state of the qubit is being read and a second value during operation of the qubit.
