Photon-Echo Quantum Memory
W. Tittel, M. Afzelius, R. L. Cone +4
The future of long-distance quantum communication relies on the availability of quantum memory, i.e. devices that allow temporal storage of quantum information. We review research…
Interference of Spontaneous Emission of Light from two Solid-State Atomic Ensembles
M. Afzelius, M. U. Staudt, H. de. Riedmatten +6
We report an interference experiment of spontaneous emission of light from two distant solid-state ensembles of atoms that are coherently excited by a short laser pulse. The ensemb…
Interference of multi-mode photon echoes generated in spatially separated solid-state atomic ensembles
M. U. Staudt, M. Afzelius, H. de Riedmatten +6
High-visibility interference of photon echoes generated in spatially separated solid-state atomic ensembles is demonstrated. The solid state ensembles were LiNbO waveguides dop…
Quantum Repeaters with Photon Pair Sources and Multi-Mode Memories
Christoph Simon, Hugues de Riedmatten, Mikael Afzelius +3
We propose a quantum repeater protocol which builds on the well-known DLCZ protocol [L.M. Duan, M.D. Lukin, J.I. Cirac, and P. Zoller, Nature 414, 413 (2001)], but which uses photo…
Analysis of a quantum memory for photons based on controlled reversible inhomogeneous broadening
Nicolas Sangouard, Christoph Simon, Mikael Afzelius +1
We present a detailed analysis of a quantum memory for photons based on controlled and reversible inhomogeneous broadening (CRIB). The explicit solution of the equations of motion…
Controlled Stark shifts in Er-doped crystalline and amorphous waveguides for quantum state storage
Sara R. Hastings-Simon, Matthias U. Staudt, Mikael Afzelius +4
We present measurements of the linear Stark effect on the I I transition in an Er-doped proton-exchanged LiNbO crystalline waveguide…
