Long-Range QKD without Trusted Nodes is Not Possible with Current Technology
Bruno Huttner, Romain Alléaume, Eleni Diamanti +11
A recently published patent (https://www.ipo.gov.uk/p-ipsum/Case/PublicationNumber/GB2590064) has claimed the development of a novel quantum key distribution protocol purporting to…
Quantum Technologies in the Telecommunications Industry
Vicente Martin, Juan Pedro Brito, Carmen Escribano +13
Quantum based technologies have been fundamental in our world. After producing the laser and the transistor, the devices that have shaped our modern information society, the possib…
Quantum Chaos and the Spectrum of Factoring
Jose Luis Rosales, Samira Briongos, Vicente Martin
There exists a Hamiltonian formulation of the factorisation problem which also needs the definition of a factorisation ensemble (a set to which factorable numbers, , havin…
The Engineering of Software-Defined Quantum Key Distribution Networks
Alejandro Aguado, Victor Lopez, Diego Lopez +5
Quantum computers will change the cryptographic panorama. A technology once believed to lay far away into the future is increasingly closer to real world applications. Quantum comp…
Quantum simulation of the integer factorization problem: Bell states in a Penning trap
Jose Luis Rosales, Vicente Martin
The arithmetic problem of factoring an integer can be translated into the physics of a quantum device, a result that supports Pólya's and Hilbert's conjecture to prove Riemann'…
Quantum Simulation of the Factorization Problem
Jose Luis Rosales, Vicente Martin
Feynman's prescription for a quantum simulator was to find a hamitonian for a system that could serve as a computer. Pólya and Hilbert conjecture was to demonstrate Riemann's hypot…
Entanglement Distribution in Optical Networks
Alex Ciurana, Vicente Martin, Jesus Martinez-Mateo +3
The ability to generate entangled photon-pairs over a broad wavelength range opens the door to the simultaneous distribution of entanglement to multiple users in a network by using…
Demystifying the Information Reconciliation Protocol Cascade
Jesus Martinez-Mateo, Christoph Pacher, Momtchil Peev +2
Cascade is an information reconciliation protocol proposed in the context of secret key agreement in quantum cryptography. This protocol allows removing discrepancies in two partia…
Quantum Metropolitan Optical Network based on Wavelength Division Multiplexing
Alex Ciurana, Jesus Martinez-Mateo, Momtchil Peev +4
Quantum Key Distribution (QKD) is maturing quickly. However, the current approaches to its application in optical networks make it an expensive technology. QKD networks deployed to…
Secure Optical Networks Based on Quantum Key Distribution and Weakly Trusted Repeaters
David Elkouss, Jesus Martinez-Mateo, Alex Ciurana +1
In this paper we explore how recent technologies can improve the security of optical networks. In particular, we study how to use quantum key distribution (QKD) in common optical n…
Analysis of a rate-adaptive reconciliation protocol and the effect of the leakage on the secret key rate
David Elkouss, Jesus Martinez-Mateo, Vicente Martin
Quantum key distribution performs the trick of growing a secret key in two distant places connected by a quantum channel. The main reason is that the legitimate users can bound the…
Blind Reconciliation
Jesus Martinez-Mateo, David Elkouss, Vicente Martin
Information reconciliation is a crucial procedure in the classical post-processing of quantum key distribution (QKD). Poor reconciliation efficiency, revealing more information tha…
Untainted Puncturing for Irregular Low-Density Parity-Check Codes
David Elkouss, Jesus Martinez-Mateo, Vicente Martin
Puncturing is a well-known coding technique widely used for constructing rate-compatible codes. In this paper, we consider the problem of puncturing low-density parity-check codes…
Improved construction of irregular progressive edge-growth Tanner graphs
Jesus Martinez-Mateo, David Elkouss, Vicente Martin
The progressive edge-growth algorithm is a well-known procedure to construct regular and irregular low-density parity-check codes. In this paper, we propose a modification of the o…
