Provably Secure and Practical Quantum Key Distribution over 307 km of Optical Fibre
Boris Korzh, Charles Ci Wen Lim, Raphael Houlmann +6
Proposed in 1984, quantum key distribution (QKD) allows two users to exchange provably secure keys via a potentially insecure quantum channel. Since then, QKD has attracted much at…
Demonstration of Quantum Nonlocality in presence of Measurement Dependence
Djeylan Aktas, Sébastien Tanzilli, Anthony Martin +3
Quantum nonlocality stands as a resource for Device Independent Quantum Information Processing (DIQIP), as, for instance, Device Independent Quantum Key Distribution. We investigat…
Quantum key distribution over a metropolitan network using an integrated photonics based prototype
Maria Ana Pereira, Giulio Gualandi, Rebecka Sax +5
An industrial-scale adoption of Quantum Key Distribution (QKD) requires the development of practical, stable, resilient and cost-effective hardware that can be manufactured at larg…
Enhanced heralded single-photon source with a photon-number-resolving parallel superconducting nanowire single-photon detector
Lorenzo Stasi, Patrik Caspar, Tiff Brydges +3
Heralded single-photon sources (HSPS) intrinsically suffer from multiphoton emission, leading to a trade-off between the source's quality and the heralding rate. A solution to this…
Phase-correlation-free quantum key distribution source operating at gigahertz rates
Shashank Kumar, Alessandro Marcomini, Loïc Millet +8
Phase randomization is essential for the security of practical decoy-state quantum key distribution (QKD) systems. Commonly, implementations rely on laser sources which are either…
Displacing entanglement back and forth between the micro and macro domains
Natalia Bruno, Anthony Martin, Pavel Sekatski +3
Quantum theory is often presented as the theory describing the microscopic world, and admittedly, it has done this extremely well for decades. Nonetheless, the question of whether…
