    "abstract": "Following a recent proposal by S. B. Zheng and G. C. Guo (Phys. Rev. Lett.\n85, 2392 (2000)), we report an experiment in which two Rydberg atoms crossing a\nnon-resonant cavity are entangled by coherent energy exchange. The process,\nmediated by the virtual emission and absorption of a microwave photon, is\ncharacterized by a collision mixing angle four orders of magnitude larger than\nfor atoms colliding in free space with the same impact parameter. The final\nentangled state is controlled by adjusting the atom-cavity detuning. This\nprocedure, essentially insensitive to thermal fields and to photon decay, opens\npromising perspectives for complex entanglement manipulations.",
