'''Secure Communication based on Quantum Cryptography''' ('''SECOQC''') is a project that aims to develop [[quantum cryptography]] (see there for further details). The [[European Union]] decided in 2004 to invest 11 million [[Euro|EUR]] in the project as a way of circumventing [[espionage]] attempts by [[ECHELON]]. [[Christian Monyk]], the coordinator of SECOQC, said people and organizations in [[Austria]], [[Belgium]], the [[United Kingdom]], [[Canada]], the [[Czech Republic]], [[Denmark]], [[France]], [[Germany]], [[Italy]], [[Russia]], [[Sweden]], and [[Switzerland]] would participate in the project.

On October 8, 2008 SECOQC was launched in Vienna.<ref>{{cite webnews|url=http://news.bbc.co.uk/1/hi/sci/tech/7661311.stm|title='Unbreakable' encryption unveiled|website=BBC News|date=9 October 2008}}</ref>

== Limitations of classical quantum cryptography ==

[[Quantum cryptography]], usually known as [[quantum key distribution]] (QKD) provides powerful security. But it has some limitations. Following no-cloning theorem, QKD only can provide one-to-one connections. So the number of links will increase <math>N(N-1)/2</math> as <math>N</math> represents the number of nodes. If a node wants to participate into the QKD network, it will cause some issues like constructing quantum communication line. To overcome these issues, SECOQC was started.
