High-Fidelity Measurement of a Superconducting Qubit Using an On-Chip Microwave Photon Counter

High-Fidelity Measurement of a Superconducting Qubit Using an On-Chip Microwave Photon Counter

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 dispersively coupled measurement resonator to map the state of the qubit to “bright” and “dark” cavity pointer states that...
