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…

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…

Loss-tolerant quantum key distribution with detection efficiency mismatch

Alessandro Marcomini, Akihiro Mizutani, Fadri Grünenfelder +2

Current implementations of quantum key distribution (QKD) typically rely on prepare-and-measure (P&M) schemes. Unfortunately, these implementations are not completely secure, unles…

The limits of multiplexing quantum and classical channels: Case study of a 2.5 GHz discrete variable quantum key distribution system

Fadri Grünenfelder, Rebecka Sax, Alberto Boaron +1

Network integration of quantum key distribution is crucial for its future widespread deployment due to the high cost of using optical fibers dedicated for the quantum channel, only…

Performance and security of 5 GHz repetition rate polarization-based Quantum Key Distribution

Fadri Grünenfelder, Alberto Boaron, Davide Rusca +2

We present and characterize a source for a 5 GHz clocked polarization-based simplified BB84 protocol. Secret keys are distributed over 151.5 km of standard telecom fiber at a rate…
