Quantum Computing and Information Transfer by Optical Manipulation of Molecular Coherences
Abstract
While formally quantum computation has become a rather well defined theoretical science, physical demonstrations are few, limited to several qubits, and to several steps in processing. At present, there is not a recognized, scalable physical method of implementation that meets the promise of true computation. We have proposed nonlinear spectroscopic methods of coherence manipulation, and in particular, Time-Frequency Resolved Coherent Anti-Stokes Raman Scattering (TFRCARS) in the molecular re-vibronic Hilbert space as a novel scheme for implementing quantum logic. The method has advantages with its demonstrable massive parallelism, therefore well suited for information transfer, while its scalability remains unresolved, both theoretically and with regard to physical implementations. We are actively following the latter, with the concept of an inhomogeneously indexed array of single quantum centers as the physical realization.
