Towards an eficient atomic frequency comb quantum memory
A. Amari, A. Walther, M. Sabooni +8
We present an efficient photon-echo experiment based on atomic frequency combs [Phys. Rev. A 79, 052329 (2009)]. Echoes containing an energy of up to 35% of that of the input pulse…
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…
Electric control of collective atomic coherence in an Erbium doped solid
Jiří Minář, Björn Lauritzen, Hugues de Riedmatten +3
We demonstrate fast and accurate control of the evolution of collective atomic coherences in an Erbium doped solid using external electric fields. This is achieved by controlling t…
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…
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…
