Evaluation of quantum key distribution systems against injection-locking attacks
Jerome Wiesemann, Fadri Grünenfelder, Ana Blázquez +2
While ideal quantum key distribution (QKD) systems are well-understood, practical implementations face various vulnerabilities, such as side-channel attacks resulting from device i…
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…
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…
Optical payload design for downlink quantum key distribution and keyless communication using CubeSats
Pedro Neto Mendes, Gonçalo Lobato Teixeira, David Pinho +6
Quantum key distribution is costly and, at the moment, offers low performance in space applications. Other more recent protocols could offer a potential practical solution to this…
Receiver-Device-Independent Quantum Key Distribution
Marie Ioannou, Maria Ana Pereira, Davide Rusca +9
We present protocols for quantum key distribution in a prepare-and-measure setup with an asymmetric level of trust. While the device of the sender (Alice) is partially characterize…
Practical self-testing quantum random number generator based on an energy bound
Davide Rusca, Thomas van Himbeeck, Anthony Martin +5
We present a scheme for a self-testing quantum random number generator. Compared to the fully device-independent model, our scheme requires an extra natural assumption, namely that…
