Cybersecurity of Quantum Key Distribution Implementations
Ittay Alfassi, Ran Gelles, Rotem Liss +1
Practical implementations of Quantum Key Distribution (QKD) often deviate from the theoretical protocols, exposing the implementations to various attacks even when the underlying (…
Improved finite-size key rates for discrete-modulated continuous variable quantum key distribution under coherent attacks
Carlos Pascual-García, Stefan Bäuml, Mateus Araújo +2
Continuous variable quantum key distribution (CVQKD) with discrete modulation combines advantages of CVQKD, such as the implementability using readily available technologies, with…
Geometry of entanglement and separability in Hilbert subspaces of dimension up to three
Rotem Liss, Tal Mor, Andreas Winter
We present a complete classification of the geometry of the mutually complementary sets of entangled and separable states in three-dimensional Hilbert subspaces of bipartite and mu…
Composable Security of Generalized BB84 Protocols Against General Attacks
Michel Boyer, Rotem Liss, Tal Mor
Quantum key distribution (QKD) protocols make it possible for two parties to generate a secret shared key. One of the most important QKD protocols, BB84, was suggested by Bennett a…
Simple and Rigorous Proof Method for the Security of Practical Quantum Key Distribution in the Single-Qubit Regime Using Mismatched Basis Measurements
Michel Boyer, Gilles Brassard, Nicolas Godbout +2
Quantum key distribution (QKD) protocols aim at allowing two parties to generate a secret shared key. While many QKD protocols have been proven unconditionally secure in theory, pr…
Non-NP-Hardness of Translationally-Invariant Spin-Model Problems
Rotem Liss, Tal Mor, Roman Shapira
Finding the ground state energy of the Heisenberg Hamiltonian is an important problem in the field of condensed matter physics. In some configurations, such as the antiferromagneti…
Security Proof Against Collective Attacks for an Experimentally Feasible Semiquantum Key Distribution Protocol
Walter O. Krawec, Rotem Liss, Tal Mor
Semiquantum key distribution (SQKD) allows two parties (Alice and Bob) to create a shared secret key, even if one of these parties (say, Alice) is classical. However, most SQKD pro…
Quantum Communication -- Celebrating the Silver Jubilee of Teleportation
Rotem Liss, Tal Mor
This is an editorial paper presenting the meaning, history, and influence of quantum teleportation.
From Practice to Theory: The "Bright Illumination" Attack on Quantum Key Distribution Systems
Rotem Liss, Tal Mor
The "Bright Illumination" attack [Lydersen et al., Nat. Photon. 4, 686-689 (2010)] is a practical attack, fully implementable against quantum key distribution systems. In contrast…
Topological order on the Bloch sphere
Rotem Liss, Tal Mor, Roman Orus
A Bloch sphere is the geometrical representation of an arbitrary two-dimensional Hilbert space. Possible classes of entanglement and separability for the pure and mixed states on t…
Attacks against a Simplified Experimentally Feasible Semiquantum Key Distribution Protocol
Michel Boyer, Rotem Liss, Tal Mor
A semiquantum key distribution (SQKD) protocol makes it possible for a quantum party and a classical party to generate a secret shared key. However, many existing SQKD protocols ar…
Composable security against collective attacks of a modified BB84 QKD protocol with information only in one basis
Michel Boyer, Rotem Liss, Tal Mor
Quantum Cryptography uses the counter-intuitive properties of Quantum Mechanics for performing cryptographic tasks in a secure and reliable way. The Quantum Key Distribution (QKD)…
Security Against Collective Attacks of a Modified BB84 QKD Protocol with Information only in One Basis
Michel Boyer, Rotem Liss, Tal Mor
The Quantum Key Distribution (QKD) protocol BB84 has been proven secure against several important types of attacks: the collective attacks and the joint attacks. Here we analyze th…
Experimentally feasible protocol for semiquantum key distribution
Michel Boyer, Matty Katz, Rotem Liss +1
Quantum key distribution (QKD) protocols make it possible for two quantum parties to generate a secret shared key. Semiquantum key distribution (SQKD) protocols, such as "QKD with…
Geometry of entanglement in the Bloch sphere
Michel Boyer, Rotem Liss, Tal Mor
Entanglement is an important concept in quantum information, quantum communication, and quantum computing. We provide a geometrical analysis of entanglement and separability for al…
