Simplified quantum key distribution implementation secure in the presence of state preparation flaws
Ainhoa Agulleiro, Fadri Grünenfelder, Raphaël Houlmann +3
We present an implementation of a three-state BB84 protocol with time-bin encoding, one decoy state and a simplified measurement scheme that uses passive basis choice. Our system s…
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…
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…
Modulator-free, self-testing quantum random number generator
Ana Blázquez-CoÃdo, Fadri Grünenfelder, Anthony Martin +3
Quantum random number generators (QRNGs) use the inherent unpredictability of quantum mechanics to generate true randomness, as opposed to classical random number generators. Howev…
