    "abstract": "We have built a microwave Fabry-Perot resonator made of diamond-machined\ncopper mirrors coated with superconducting niobium. Its damping time (Tc = 130\nms at 51 GHz and 0.8 K) corresponds to a \u0026#64257;nesse of 4.6 x 109, the\nhighest ever reached for a Fabry-Perot in any frequency range. This result\nopens novel perspectives for quantum information, decoherence and non-locality\nstudies.",
