Qubit Noise Sensing via Induced Photon Loss in a Superconducting Cavity
feeds.aps.org · By Nitzan Kahn, Dror Garti, Uri Goldblatt, Lalit M. Joshi, Fabien Lafont & Serge Rosenblum ·
The 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.
