Direct Observation of Spontaneous Photon Down-Conversion in a Superconducting Quantum Circuit
January 15, 2025
Researchers from the Quantum Computing and Technologies (QCT) group at the Institut de Física d’Altes Energies (IFAE) have published a new result in Physical Review Letters reporting the direct observation of spontaneous photon down-conversion in a superconducting quantum circuit. The work demonstrates that a single microwave photon can decay into three lower-energy photons at a Josephson junction, revealing a new regime of light–matter interaction relevant for quantum optics and superconducting qubit technologies.
