Abstract

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.
