Nokia and British scientists develop quantum cryptography for mobile phones




Scientists have developed a method of cooperation with Nokia to bring. A form of quantum cryptography for mobile phones The method is based on quantum key distribution that normally works with ‘fixed’ set-ups only.

The method was developed by the Centre for Quantum Photonics at the University of Bristol, in collaboration with Nokia. The development team demonstrated a form of quantum key distribution that is suitable for mobile phones. This form of encryption that works with entangled particles are usually large setups with hardware needed, but scientists and Nokia managed to build into mobile phones. Hardware The concept makes use of quantum encryption on mobile phones in the future.

To make mobile quantum cryptography possible, scientists have developed a new protocol, which they published the details in the scientific journal Physical Review Letters. The system works with entangled photons, a quantum mechanical property in which two particles ‘linked’ to and accept each other’s properties. In the future, the creators want their concept in the practice tests on a conventional mobile network.

Previously demonstrated that scientists already it is possible using a conventional fiber optic network exchange. quantum encryption keys And recently succeeded scientists managed to send quantum information of entangled photons to multiple recipients, a development that contributes to making quantum encryption methods.
