Criptografía Cuántica en Redes Clásicas.
"Revista Española de Física", v. 21
Quantum Key Distribution (QKD) is the first technology derived from Quantum Information and Quantum Computation that is being marketed. To date, the commercial applications are in the encryption of point to point links. Now, the next logical step is about to be taken. Full quantum networks able to transport the keys to be used in symmetric key cryptography with a security level previously unattained are being designed. The proof of concept of many of the ingredients needed exist and networks with a few nodes have been implemented. The first networks will cover a metropolitan area and demonstrate the feasibility of large-scale QKD integrated with classical networks. If it succeeds in the marketplace, this could signal a major shift in how cryptography is used today.
