Qubit Measurement by Multichannel Driving

2018 · arXiv (Cornell University)

We theoretically propose and experimentally implement a method of measuring a qubit by driving it close to the frequency of a dispersively coupled bosonic mode. The separation of the bosonic states corresponding to different qubit …

Single-shot readout of a superconducting qubit using a thermal detector

2024 · Nature Electronics

Abstract Measuring the state of a qubit is a key fundamental operation of a quantum computer. High-fidelity single-shot readout of superconducting qubits can be achieved using parametric amplifiers at millikelvin temperatures. However, scaling parametric amplifiers …
