    Quantum metrology of low-frequency electromagnetic modes with frequency upconverters by Stephen E.

Rapidis, Maria Simanovskaia, Jyotirmai Singh, Cyndia Yu, Kent D. Irwin

    Published in Physical Review Research (2025-03-01)
    “…We present the RF Quantum Upconverter (RQU) and describe its application to quantum metrology of electromagnetic modes between dc and the very high frequency band (VHF) (≲300 MHz). The RQU uses a Josephson interferometer made up of superconducting loops and Josephson junctions to implement a parametric interaction between a low-frequency electromagnetic mode (between dc and VHF) and a mode in the microwave C Band (∼5 GHz), analogous to the radiation pressure interaction between electromagnetic and mechanical modes in cavity optomechanics. …”
