Efficient Reconciliation of Continuous Variable Quantum Key Distribution with Multiplicatively Repeated Non-Binary LDPC Codes
Jesus Martinez-Mateo, David Elkouss
Continuous variable quantum key distribution bears the promise of simple quantum key distribution directly compatible with commercial off the shelf equipment. However, for a long t…
Information Reconciliation for Continuous-Variable Quantum Key Distribution using Non-Binary Low-Density Parity-Check Codes
Christoph Pacher, Jesus Martinez-Mateo, Jörg Duhme +2
An information reconciliation method for continuous-variable quantum key distribution with Gaussian modulation that is based on non-binary low-density parity-check (LDPC) codes is…
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…
Fundamental Finite Key Limits for One-Way Information Reconciliation in Quantum Key Distribution
Marco Tomamichel, Jesus Martinez-Mateo, Christoph Pacher +1
The security of quantum key distribution protocols is guaranteed by the laws of quantum mechanics. However, a precise analysis of the security properties requires tools from both c…
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

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…
Information Reconciliation for Quantum Key Distribution
David Elkouss, Jesus Martinez-Mateo, Vicente Martin
Quantum key distribution (QKD) relies on quantum and classical procedures in order to achieve the growing of a secret random string -the key- known only to the two parties executin…
QKD in Standard Optical Telecommunications Networks
D. Lancho, J. Martinez, D. Elkouss +2
To perform Quantum Key Distribution, the mastering of the extremely weak signals carried by the quantum channel is required. Transporting these signals without disturbance is custo…
