    "abstract": "We describe a technique for manipulating quantum information stored in\ncollective states of mesoscopic ensembles. Quantum processing is accomplished\nby optical excitation into states with strong dipole-dipole interactions. The\nresulting ``dipole blockade\u0027\u0027 can be used to inhibit transitions into all but\nsingly excited collective states. This can be employed for a controlled\ngeneration of collective atomic spin states as well as non-classical photonic\nstates and for scalable quantum logic gates. An example involving a cold\nRydberg gas is analyzed.",
