Summary
We enhanced photon-pressure coupling in superconducting circuits using Kerr amplification, improving RF sensing and quantum photonics. This work advances Kerr cavity optomechanics and quantum-limited radio-frequency sensing.
Area of Science:
- Quantum physics

Purpose of the Study:
- To implement and enhance photon-pressure coupling between two superconducting circuits.
- To investigate the role of Kerr amplification in improving coupling rates and cooperativity.
- To explore applications in quantum-limited RF sensing and quantum photonics.
Main Methods:
- Utilizing two superconducting circuits, one as a parametric amplifier.
- Employing Kerr-based enhancement of the single-photon coupling rate.
- Measuring changes in cooperativity and RF signal detection imprecision.
Main Results:
- Demonstrated Kerr-based enhancement of photon-pressure coupling rate.
- Achieved a one-order-of-magnitude increase in cooperativity in the amplifier regime.
- Observed reduced measurement imprecision in RF signal detection due to intracavity amplification.
- Found RF mode sideband cooling is not limited by amplifier mode temperature, suggesting nonreciprocal heat transfer.
Conclusions:
