On the security of two-way quantum key distribution

Jesni Shamsul Shaari, Stefano Mancini, Stefano Pirandola +1

An author (arXiv:1709.09262 [quant-ph] (2017), Nanoscale Research Letters (2017) 12:552) has recently questioned the security of two-way quantum key distribution schemes by referri…

Assumptions in Quantum Cryptography

Normand J. Beaudry

Quantum cryptography uses techniques and ideas from physics and computer science. The combination of these ideas makes the security proofs of quantum cryptography a complicated tas…

Squashing model for detectors and applications to quantum key distribution protocols

Oleg Gittsovich, Normand J. Beaudry, Varun Narasimhachar +3

We develop a framework that allows a description of measurements in Hilbert spaces that are smaller than their natural representation. This description, which we call a "squashing…

Smooth Max-Information as One-Shot Generalization for Mutual Information

Nikola Ciganović, Normand J. Beaudry, Renato Renner

We study formal properties of smooth max-information, a generalization of von Neumann mutual information derived from the max-relative entropy. Recent work suggests that it is a us…

An intuitive proof of the data processing inequality

Normand J. Beaudry, Renato Renner

The data processing inequality (DPI) is a fundamental feature of information theory. Informally it states that you cannot increase the information content of a quantum system by ac…

Entanglement verification with realistic measurement devices via squashing operations

Tobias Moroder, Otfried Gühne, Normand J. Beaudry +2

Many protocols and experiments in quantum information science are described in terms of simple measurements on qubits. However, in a real implementation, the exact description is m…
