An Efficient Secret Communication Scheme for the Bosonic Wiretap Channel
Esther Hänggi, Iyán Méndez Veiga, Ligong Wang
We propose a new secret communication scheme over the bosonic wiretap channel. It uses readily available hardware such as lasers and direct photodetectors. The scheme is based on r…
Reproducible Builds for Quantum Computing
Iyán Méndez Veiga, Esther Hänggi
Reproducible builds are a set of software development practices that establish an independently verifiable path from source code to binary artifacts, helping to detect and mitigate…
Impossibility of Quantum Private Queries
Esther Hänggi, Severin Winkler
Symmetric private information retrieval is a cryptographic task allowing a user to query a database and obtain exactly one entry without revealing to the owner of the database whic…
randextract: a Reference Library to Test and Validate Privacy Amplification Implementations
Iyán Méndez Veiga, Esther Hänggi
Quantum cryptographic protocols do not rely only on quantum-physical resources, they also require reliable classical communication and computation. In particular, the secrecy of an…
