Quantum information processing with single photons and atomic ensembles - David Petrosyan

Scalable and efficient quantum computation with photonic qubits requires deterministic sources of single photons, robust reversible photon storage, giant nonlinearities capable of entangling pairs of photons, and efficient photon detectors. I will discuss several related techniques, based on the coherent manipulation of atomic ensembles in the regime of electromagnetically induced transparency, that are capable of implementing all of the above prerequisites for deterministic optical quantum computation with single photons.
