Rydberg interactions can be applied in a variety of ways enabling control of single atom qubits, multi-atom ensemble qubits, and hybrid entanglement between different types of atoms, between atoms and photons,  or between atoms and solid state qubits. In experiments with N~10 atom ensembles we demonstrate preparation of entangled W states, and strong blockade between spatially separated ensembles. In an array of single atom qubits we demonstrate high fidelity single qubit gates, and improved fidelity of Rydberg blockade mediated entanglement, surpassing all previous experiments. Progress towards a hybrid atom-superconductor interface based on entanglement of a single atom in a cryostat and a microwave photon will be presented.
