Abstract

We present our experiments on the applicability of ultracold Rydberg gases for quantum information processing. As quantum computing relies on entanglement mediated through interparticle interactions, we have experimentally implemented three approaches to induce ultralong‐range interactions between Rydberg atoms: van‐der‐Waals interactions, interactions of permanent dipoles induced by an electric field, and resonant dipole‐dipole interactions (Förster resonances). Advantages and limitations of the approaches are discussed.
