1. A method for measuring one or more qubits, the method comprising:
sending a signal into a readout cavity to probe a qubit that resides in the readout cavity, resulting in an entangled signal from which to derive a measurement of the qubit;
swapping the entangled signal between the readout cavity and an amplifier device using a tunable coupling between the readout cavity and the amplifier device by connecting a superconducting switch for a duration of time to allow a parametric amplifier in the amplifier device to receive the entangled signal;
amplifying the entangled signal to produce an amplified signal; and
reading out the amplified to a measurement sub-system.
