The first practical way of carrying out quantum cryptography using a mobile phone has been developed by researchers at Nokia and the University of Bristol in the UK. Quantum cryptography – which allows messages to be sent with complete secrecy – is currently limited to banks and other organizations that can afford to have expensive and extremely sensitive quantum-optical components at both ends of a communications link. What the Nokia/Bristol team has done is to work out how to perform “quantum key distribution” (QKD) using simple and potentially inexpensive “client” electronics that could be integrated within a single chip.
So, seems Asha and Lumia phones will be more secure for business once this tech hits Nokia devices and we know how much Nokia and MS targeting enterprises.
