== 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 1:1 connection. So the number of links will increase N(N-1)/2 as N 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 this issues, SECOQC was started.
