Abstract
Methods and apparatuses are provided for controlling the state of a qubit. A qubit apparatus includes a load, a qubit, and a compound Josephson junction coupler coupling the qubit to the load. A coupling controller controls the coupling strength of the compound Josephson junction coupler such that a coupling between the qubit and the load is a first value when a reset of the qubit is desired and a second value during operation of the qubit.
