Continuous-variable approximate unitary 2-design, with applications to unclonable encryption
Arpan Akash Ray, Boris Skoric
We introduce an -approximate unitary 2-design that is compatible with the structure of p- and q-quadratures in continuous-variable (CV) quantum systems. The design uni…
Dispersive Hong-Ou-Mandel Interference with Finite Coincidence Windows
T. J. Walstra, A. J. Hasenack, D. J. de Ruiter +3
Hong-Ou-Mandel (HOM) interference is a fundamental tool for assessing photon indistinguishability in quantum information processing. While the effect of chromatic dispersion on HOM…
Short Blocklength Error Correction Codes for Continuous-Variable Quantum Key Distribution
Kadir Gümüş, João dos Reis Frazão, Boris Škorić +4
We introduce a two-step error correction scheme for reconciliation in continuous-variable quantum key distribution systems. Using this scheme, it is possible to use error correctio…
Authentication of Continuous-Variable Quantum Messages
Mehmet Hüseyin Temel, Boris Škorić
We introduce the first quantum authentication scheme for continuous-variable states. Our scheme is based on trap states, and is an adaptation of a discrete-variable scheme by Broad…
A Critical Analysis of Deployed Use Cases for Quantum Key Distribution and Comparison with Post-Quantum Cryptography
Nick Aquina, Bruno Cimoli, Soumya Das +7
Quantum Key Distribution (QKD) is currently being discussed as a technology to safeguard communication in a future where quantum computers compromise traditional public-key cryptos…
Noise characterization for co-propagation of classical and CV-QKD signals over fiber and free-space link
João dos Reis Frazão, Vincent van Vliet, Kadir Gümüş +5
Real-time CV-QKD receiver achieves peak 2.9 Mbit/s secret-key-rates over 12.8 km of fiber, while co-propagating 15 classical channels, separated 1 nm from the quantum signal. Perfo…
Co-propagation of Classical and Continuous-variable QKD Signals over a Turbulent Optical Channel with a Real-time QKD Receiver
João dos Reis Frazão, Vincent van Vliet, Sjoerd van der Heide +5
We demonstrate classical and quantum signal co-propagation over a turbulent free-space channel with 3 Tbit/s throughput and record 2.7 Mbit/s secret-key rate. Our real-time GPU-bas…
Can't Touch This: unconditional tamper evidence from short keys
Bart van der Vecht, Xavier Coiteux-Roy, Boris Skoric
Storing data on an external server with information-theoretic security, while using a key shorter than the data itself, is impossible. As an alternative, we propose a scheme that a…
