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…
Proposal for Implementing Device-Independent Quantum Key Distribution based on a Heralded Qubit Amplification
Nicolas Gisin, Stefano Pironio, Nicolas Sangouard
In device-independent quantum key distribution (DIQKD), the violation of a Bell inequality is exploited to establish a shared key that is secure independently of the internal worki…
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…
Purification of Single-photon Entanglement
D. Salart, O. Landry, N. Sangouard +8
Single-photon entanglement is a simple form of entanglement that exists between two spatial modes sharing a single photon. Despite its elementary form, it provides a resource as us…
