Quantum computing with a single molecular ensemble and a Cooper-pair box
Karl Tordrup and Klaus M{\o}lmer

We propose to encode quantum information in rotational excitations in a molecular ensemble. Using a stripline cavity field for quantum state transfer between the molecular ensemble and a Cooper pair box two-level system, our proposal offers a linear scaling of the number of qubits in our register with the number of rotationally excited states available in the molecules.
