Precision requirements for spin-echo based quantum memories
Khabat Heshami, Nicolas Sangouard, Jiri Minar +2
Spin echo techniques are essential for achieving long coherence times in solid-state quantum memories for light because of inhomogeneous broadening of the spin transitions. It has…
Quantum Storage of Photonic Entanglement in a Crystal
Christoph Clausen, Imam Usmani, Felix Bussieres +4
Entanglement is the fundamental characteristic of quantum physics. Large experimental efforts are devoted to harness entanglement between various physical systems. In particular, e…
Spin Wave Storage using Chirped Control Fields in Atomic Frequency Comb based Quantum Memory
Jiří Minář, Nicolas Sangouard, Mikael Afzelius +2
It has been shown that an inhomogeneously broadened optical transition shaped into an atomic frequency comb can store a large number of temporal modes of the electromagnetic field…
Temporally multiplexed quantum repeaters with atomic gases
Christoph Simon, Hugues de Riedmatten, Mikael Afzelius
We propose a temporally multiplexed version of the Duan-Lukin-Cirac-Zoller (DLCZ) quantum repeater protocol using controlled inhomogeneous spin broadening in atomic gases. A first…
Quantum Memories. A Review based on the European Integrated Project "Qubit Applications (QAP)"
C. Simon, M. Afzelius, J. Appel +21
We perform a review of various approaches to the implementation of quantum memories, with an emphasis on activities within the quantum memory sub-project of the EU Integrated Proje…
On the impossibility of faithfully storing single-photons with the three-pulse photon echo
Nicolas Sangouard, Christoph Simon, Jiri Minar +6
The three-pulse photon echo is a well-known technique to store intense light pulses in an inhomogeneously broadened atomic ensemble. This protocol is attractive because it is relat…
Mapping multiple photonic qubits into and out of one solid-state atomic ensemble
Imam Usmani, Mikael Afzelius, Hugues de Riedmatten +1
The future challenge of quantum communication are scalable quantum networks, which require coherent and reversible mapping of photonic qubits onto stationary atomic systems (quantu…
