Quantum Cryptography: Hacking is Futile

An international team has successfully implemented an advanced form of quantum cryptography for the first time. Moreover, encryption is independent of the quantum device used and therefore even more secure against hacking attempts.

The Internet is teeming with highly sensitive information. Sophisticated encryption techniques generally ensure that such content cannot be intercepted and read. But in the future high-performance quantum computers could crack these keys in a matter of seconds. It is just as well, then, that quantum mechanical techniques not only enable new, much aster algorithms, but also exceedingly effective cryptography.

Quantum key distribution (QKD) is secure against attacks on the communication channel, but not against attacks on or manipulations of the devices...
