Generation of single photons of alternating polarization

Abstract

We present first results of single-photon generation from an atom-cavity system, where Raman transitions are driven between Zeeman sublevels. The process results in photons with alternating polarisations and requires no repumping.

Scheme for generating a sequence of single photons of alternating polarization

Tatjana Wilk, Holger Specht, S. C. Webster +2 more

Single-photons of well-defined polarization that are deterministically generated in a single spatio-temporal field mode are the key to the creation of multi-partite entangled states in photonic networks. Here, we present a novel scheme to produce such photons from a single atom in an optical cavity, by means of vacuum-stimulated Raman transitions between the Zeeman substates of a single hyperfine state. Upon each transition, a photon is emitted into the cavity, with a polarization that depends on the direction of the Raman process.

Polarization-Controlled Single Photons

Tatjana Wilk, S. C. Webster, Holger Specht +2 more

Vacuum-stimulated Raman transitions are driven between two magnetic substates of a 87Rb atom strongly coupled to an optical cavity. A magnetic field lifts the degeneracy of these states, and the atom is alternately exposed to laser pulses of two different frequencies. This produces a stream of single photons with alternating circular polarization in a predetermined spatiotemporal mode. MHz repetition rates are possible as no recycling of the atom between photon generations is required. Photon indistinguishability is tested by time-resolved two-photon interference.

Deterministic Single-Photon Source for Distributed Quantum Networking

Axel Kuhn, Markus Hennrich, Gerhard Rempe

A sequence of single photons is emitted on demand from a single three-level atom strongly coupled to a high-finesse optical cavity. The photons are generated by an adiabatically driven stimulated Raman transition between two atomic ground states, with the vacuum field of the cavity stimulating one branch of the transition, and laser pulses deterministically driving the other branch. This process is unitary and therefore intrinsically reversible, which is essential for quantum communication and networking, and the photons should be appropriate for all-optical quantum information processing.
