Kind: research · Impact: medium

## In brief

- The paper proposes a method for sensing qubit noise via induced photon loss in a superconducting cavity.
- Conventional noise-sensing methods typically use the qubit itself as the sensor.
- Characterizing noise is presented as essential for improving coherence and gate performance in superconducting qubits.

## Why it matters

Noise characterization underpins efforts to improve coherence and gate performance of superconducting qubits, and a sensing approach that does not rely on the qubit itself could offer an alternative to conventional methods.
