    "abstract": "Using a single circular Rydberg atom, we have prepared two modes of a\nsuperconducting cavity in a maximally entangled state. The two modes share a\nsingle photon. This entanglement is revealed by a second atom probing, after a\ndelay, the correlations between the two modes. This experiment opens\ninteresting perspectives for quantum information manipulation and fundamental\ntests of quantum theory.",
