High-Fidelity Measurement of a Superconducting Qubit using an On-Chip Microwave Photon Counter
A. Opremcak, C. H. Liu, C. Wilen +10
We describe an approach to the high-fidelity measurement of a superconducting qubit using an on-chip microwave photon counter. The protocol relies on the transient response of a di…
