    "abstract": "We investigate a hybrid quantum circuit where ensembles of cold polar\nmolecules serve as long-lived quantum memories and optical interfaces for solid\nstate quantum processors. The quantum memory realized by collective spin states\n(ensemble qubit) is coupled to a high-Q stripline cavity via microwave Raman\nprocesses. We show that for convenient trap-surface distances of a few $\\mu$m,\nstrong coupling between the cavity and ensemble qubit can be achieved. We\ndiscuss basic quantum information protocols, including a swap from the cavity\nphoton bus to the molecular quantum memory, and a deterministic two qubit gate.\nFinally, we investigate coherence properties of molecular ensemble quantum\nbits.",
