Instead, Makarov uses it to eavesdrop on quantum cryptography systems, which transmit top - secret information in networks across the world. (newscientist.com)
Makarov's group and others have already found some weak spots in quantum cryptography, and there are potentially many more. (newscientist.com)
The experiment adapted devices built to do a more standard form of quantum cryptography known as quantum key distribution (QKD), a scheme that generates random numbers for scrambling communication. (sciencedaily.com)
