Abstract

We consider different ways of engineering quantum states of light and atoms via their interaction. First, we show that with atoms in optical lattices one may induce quantum gates between two photons. Then, I will give some procedures to create entangled states of ions and atoms in optical lattices. Those states have the property that can be mapped into photonic states by using interference, in such a way that one ends up with several entangled photons. The mapping is triggered by a laser pulse, and the emerging photons are collimated even in the absence of a cavity.
