Quantum entanglement of single spins and photons

[30-01-2012]

Diamond has recently emerged as a unique material for quantum science and engineering. In particular, Nitrogen-Vacancy centers (NV centers) in diamond exhibit quantum behaviour up to room temperature. NV centers naturally emit photons one at a time and can be used as a reliable single-photon source. Moreover, the electronic and nuclear spin states associated with the NV center have extremely long coherence times. This allows for coherent control of single spins with very high fidelity that is unmatched in the solid state. Our research aims at controlling single and coupled spins in diamond and at coupling single spins to single photons in order to establish long-distant entanglement. Besides demonstrating the basic elements of quantum information processing (at room temperature), we are interested in fundamental issues in quantum mechanics related to decoherence and light-matter interaction. Excellent candidates are encouraged to contact Ronald Hanson for up-to-date information on available projects.
