Single-shot readout of a superconducting qubit using a thermal detector
Bolometers the thing!
quote:
Nanobolometers have been shown to be fast and sensitive enough for the readout
of superconducting qubits, reaching thermal time constants in the range of hundreds
of nanoseconds and energy resolution of a few typical microwave photon
