LONDON: Researchers have come up with a way of protecting telecoms networks using quantum cryptography without the need for expensive dedicated optical-fibre links.

The technique, developed by Toshiba’s European research laboratory in Britain and Cambridge University engineers, is a step towards perfect security for everything from credit card transactions to private health records.
