Abstract
Provided is a low noise amplifier circuit for a quantum computer. The low noise amplifier circuit comprises a plurality of input stages, a shared output stage, and a voltage controller. Each input stage is coupled to one or more qubits. The shared output stage is coupled to the plurality of input stages. The voltage controller is coupled to the plurality of input stages and the shared output stage. The voltage controller is configured to selectively activate an input stage of the plurality of input stages in order to read a qubit coupled to the input stage.
