Abstract: 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.

Abstract: A technique relates to an assembly for a quantum computing device. A quantum bus plane includes a first set of recesses. A readout plane includes a second set of recesses. A block is positioned to hold the readout plane opposite the quantum bus plane, such that the first set of recesses opposes the second set of recesses. A plurality of qubit chips are included where each has a first end positioned in the first set of recesses and has a second end positioned in the second set of recesses.

Abstract: A technique relates to an assembly (500) for a quantum computing device. A quantum bus plane (100) includes a first set of recesses (201). A readout plane (102) includes a second set of recesses (301). A block (502) is positioned to hold the readout plane (102) opposite the quantum bus plane (100), such that the first set of recesses (201) opposes the second set of recesses (301). A plurality of qubit chips (101) are included where each has a first end positioned in the first set of recesses (201) and has a second end positioned in the second set of recesses (301).
