摘要
Techniques relate to reading a qubit coupled to a microwave resonator. A microwave signal at a microwave resonator frequency is input to the microwave resonator that couples to the qubit. A microwave readout signal from the microwave resonator is output to a microwave to optical converter. The microwave readout signal includes a qubit state of the qubit. The microwave to optical converter is configured to convert the microwave readout signal to an optical signal. In response to the optical signal being output by the microwave to optical converter, it is determined that the qubit is in a predefined qubit state. In response to no optical signal being output by the microwave to optical converter, it is determined that the qubit is not in the predefined qubit state.
