Researchers have developed a new method to overcome one of the main issues in implementing a quantum cryptography system, raising the prospect of a usable ‘unbreakable’ method for sending sensitive information hidden inside particles of light. By ‘seeding’ one laser beam inside another, the researchers, from the University of Cambridge and Toshiba Research Europe, have Read more about A new method of implementing an ‘unbreakable’ quantum cryptographic system[…]
