The quantum information and computation research group at Technical University of Madrid (UPM) consists of researchers within three different centers:

The core of members is formed by associate professors in the areas of security, networking and computational sciences.

The group has installed the first point to point quantum key distribution link in the country, together with Telefónica R&D. They have built a QKD network prototype where research concerning quantum protocols and its integration within standard networking technologies is being carried out.

Main research topics

Quantum information and computation: quantum cryptography and quantum key distribution (QKD). Special interest on the integration of QKD in comercial networks and standard optical communication networks. QKD-key and network management. Quantum computing. Quantum error correction.

Information and communication theory: secret-key distillation, error correction or information reconciliation for quantum key distribution.
