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…
Quantum circuit algorithm for topological invariants of second order topological many-body quantum magnets
Sebastián Domínguez-Calderón, Marcel Niedermeier, Jose L. Lado +1
Topological quantum matter represents a flexible playground to engineer unconventional excitations. While non-interacting topological single-particle systems have been studied in d…
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…
Fast Single Photon Detectors and real-time Key Distillation: Enabling High Secret Key Rate QKD Systems
Fadri Grünenfelder, Alberto Boaron, Matthieu Perrenoud +11
Quantum Key Distribution has made continuous progress over the last 20 years and is now commercially available. However, the secret key rates (SKR) are still limited to a few Mbps.…
Feynman Path Integral of a charged anisotropic HO in crossed electric and magnetic fields. Alternative calculational methods
Cyril Belardinelli
In the present paper the author evaluates the path integral of a charged anisotropic Harmonic Oscillator (HO) in crossed electric and magnetic fields by two alternative methods. Bo…
