Arbitrarily Loss-Tolerant Quantum Position Verification in a Single Execution
Llorenç Escolà -Farrà s, Boris Å koriÄ, Florian Speelman
Quantum position verification (QPV) seeks to certify the spatial location of an untrusted prover, but is challenged fundamentally by entanglement-based attacks and experimentally b…
Information Reconciliation for Continuous-Variable Quantum Key Distribution with Using Short Blocklength Error Correction Codes: Proposal and Concerns
Kadir GümüÅ, João dos Reis Frazão, Aaron Albores-Mejia +5
In this paper, we introduce a reconciliation protocol with a two-step error correction scheme that uses a short-blocklength, low-rate code and a long-blocklength, high-rate code. W…
Practical Unclonable Encryption with Continuous Variables
Arpan Akash Ray, Boris Å koriÄ
We propose the first continuous-variable (CV) unclonable encryption scheme, extending the paradigm of quantum encryption of classical messages (QECM) to CV systems. In our construc…
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 GümüŠ+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…
