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…
Daylight quantum keyless private communication for free-space links
Pedro Neto Mendes, Preeti Yadav, Lourenço Sumares +3
Quantum key distribution (QKD) is the most established approach in quantum communication. However, long-distance free-space implementations, particularly satellite links, remain ch…
Quantum Keyless Private Communication under intense background noise
Pedro Neto Mendes, Davide Rusca, Hugo Zbinden +1
Quantum key distribution relies on quantum mechanics to securely distribute cryptographic keys, offering security but necessitating complex infrastructure and significant resources…
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…
Modeling and Characterization of Arbitrary Order Pulse Correlations for Quantum Key Distribution
Ainhoa Agulleiro, Fadri Grünenfelder, Margarida Pereira +4
In quantum key distribution (QKD) implementations, memory effects caused by the limited bandwidth of modulators and/or other active devices can leak information about previous sett…
