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-Coído, 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…
Fast Single Photon Detectors and real-time Key Distillation: Enabling High Secret Key Rate QKD Systems
Fadri Grünenfelder, Alberto Boaron, Matthieu Perrenoud +11
Quantum Key Distribution has made continuous progress over the last 20 years and is now commercially available. However, the secret key rates (SKR) are still limited to a few Mbps.…
Experimental relativistic zero-knowledge proofs
Pouriya Alikhani, Nicolas Brunner, Claude Crépeau +5
Protecting secrets is a key challenge in our contemporary information-based era. In common situations, however, revealing secrets appears unavoidable, for instance, when identifyin…
Simple 2.5 GHz time-bin quantum key distribution
Alberto Boaron, Boris Korzh, Raphael Houlmann +7
We present a 2.5 GHz quantum key distribution setup with the emphasis on a simple experimental realization. It features a three-state time-bin protocol based on a pulsed diode lase…
MHz-rate semi-device-independent quantum random number generators based on unambiguous state discrimination
Jonatan Bohr Brask, Anthony Martin, William Esposito +4
An approach to quantum random number generation based on unambiguous quantum state discrimination (USD) is developed. We consider a prepare-and-measure protocol, where two non-orth…
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-…
24-Hour Relativistic Bit Commitment
Ephanielle Verbanis, Anthony Martin, Raphaël Houlmann +3
Bit commitment is a fundamental cryptographic primitive in which a party wishes to commit a secret bit to another party. Perfect security between mistrustful parties is unfortunate…
Quantum random number generation for 1.25 GHz quantum key distribution systems
A. Martin, B. Sanguinetti, C. C. W. Lim +2
Security proofs of quantum key distribution (QKD) systems usually assume that the users have access to source of perfect randomness. State-of-the-art QKD systems run at frequencies…
Practical relativistic bit commitment
Tommaso Lunghi, Jędrzej Kaniewski, Felix Bussieres +4
Bit commitment is a fundamental cryptographic primitive in which Alice wishes to commit a secret bit to Bob. Perfectly secure bit commitment between two mistrustful parties is impo…
