Ultrahigh finesse Fabry-Pérot superconducting resonator
The authors have built a microwave Fabry-Pérot resonator made of diamond-machined copper mirrors coated with superconductingniobium. Its damping time (Tc=130ms at 51GHz and 0.8K) corresponds to a finesse of 4.6×10⁹, the highest ever reached for a Fabry-Pérot in any frequency range. This result opens many perspectives for quantum information processing, decoherence and nonlocality studies.
