Quantum repeaters based on heralded qubit amplifiers
Jiří Minář, Hugues de Riedmatten, Nicolas Sangouard
We present a quantum repeater scheme based on the recently proposed qubit amplifier [N. Gisin, S. Pironio and N. Sangouard, Phys. Rev. Lett. 105, 070501 (2010)]. It relies on a on-…
Heralded quantum entanglement between two crystals
Imam Usmani, Christoph Clausen, Felix Bussieres +3
Quantum networks require the crucial ability to entangle quantum nodes. A prominent example is the quantum repeater which allows overcoming the distance barrier of direct transmiss…
Detector imperfections in photon-pair source characterization
P. Sekatski, N. Sangouard, F. Bussieres +3
We analyze how imperfections in single-photon detectors impact the characterization of photon-pair sources. We perform exact calculations to reveal the effects of multi-pair emissi…
A photon-pair source with controllable delay based on shaped inhomogeneous broadening of rare-earth doped solids
Pavel Sekatski, Nicolas Sangouard, Nicolas Gisin +2
Spontaneous Raman emission in atomic gases provides an attractive source of photon pairs with a controllable delay. We show how this technique can be implemented in solid state sys…
Faithful entanglement swapping based on sum-frequency generation
Nicolas Sangouard, Bruno Sanguinetti, Noe Curtz +3
We show that the entanglement resulting from an entanglement swapping operation performed with spontaneous parametric down-conversion can be made faithful without post-selection us…
