Detector-device-independent QKD: security analysis and fast implementation
Alberto Boaron, Boris Korzh, Raphael Houlmann +4
One of the most pressing issues in quantum key distribution (QKD) is the problem of detector side- channel attacks. To overcome this problem, researchers proposed an elegant "time-…
Quantum cloning with an optical fiber amplifier
Sylvain Fasel, Nicolas Gisin, Gregoire Ribordy +2
It has been shown theoretically that a light amplifier working on the physical principle of stimulated emission should achieve optimal quantum cloning of the polarization state of…
Quantum Metropolitan Optical Network based on Wavelength Division Multiplexing
Alex Ciurana, Jesus Martinez-Mateo, Momtchil Peev +4
Quantum Key Distribution (QKD) is maturing quickly. However, the current approaches to its application in optical networks make it an expensive technology. QKD networks deployed to…
Integrated AlGaAs source of highly indistinguishable and energy-time entangled photons
Claire Autebert, Natalia Bruno, Anthony Martin +6
The generation of nonclassical states of light in miniature chips is a crucial step towards practical implementations of future quantum technologies. Semiconductor materials are id…
High resolution optical time domain reflectometer based on 1.55um up-conversion photon-counting module
Matthieu Legre, Rob Thew, Hugo Zbinden +1
We implement a photon-counting Optical Time Domain Reflectometer (OTDR) at 1.55um which exhibits a high 2-point resolution and a high accuracy. It is based on a low temporal-jitter…
High-speed integrated QKD system
Rebecka Sax, Alberto Boaron, Gianluca Boso +10
Quantum key distribution (QKD) is nowadays a well established method for generating secret keys at a distance in an information-theoretic secure way, as the secrecy of QKD relies o…
