Quantum repeaters with entangled coherent states
Nicolas Sangouard, Christoph Simon, Nicolas Gisin +3
Entangled coherent states can be prepared remotely by subtracting non-locally a single photon from two quantum superpositions of coherent states, the so-called "Schroedinger's cat"…
Telecommunication-wavelength solid-state memory at the single photon level
Björn Lauritzen, Jiří Minář, Hugues de Riedmatten +4
We demonstrate experimentally the storage and retrieval of weak coherent light fields at telecommunication wavelengths in a solid. Light pulses at the single photon level are store…
Demonstration of atomic frequency comb memory for light with spin-wave storage
Mikael Afzelius, Imam Usmani, Atia Amari +8
We present a light-storage experiment in a praseodymium-doped crystal where the light is mapped onto an inhomogeneously broadened optical transition shaped into an atomic frequency…
Quantum repeaters based on atomic ensembles and linear optics
Nicolas Sangouard, Christoph Simon, Hugues de Riedmatten +1
The distribution of quantum states over long distances is limited by photon loss. Straightforward amplification as in classical telecommunications is not an option in quantum commu…
Quantum Repeaters based on Single Trapped Ions
Nicolas Sangouard, Romain Dubessy, Christoph Simon
We analyze the performance of a quantum repeater protocol based on single trapped ions. At each node, single trapped ions embedded into high finesse cavities emit single photons wh…
Creating Single Collective Atomic Excitations via Spontaneous Raman Emission in Inhomogeneously Broadened Systems : Beyond the Adiabatic Approximation
Carlo Ottaviani, Christoph Simon, Hugues de Riedmatten +4
The creation of single collective excitations in atomic ensembles via spontaneous Raman emission plays a key role in several quantum communication protocols, starting with the semi…
