Quantum Leap
Mr Bajcsy said that a distant application of controlling light would be in powerful quantum computers.
"In [quantum computers] you would have to transfer the information from photon to photon to photon. And in order to do that you have to make the photons interact with each other such that you control it very precisely," he told BBC News Online.
Professor M. Suhail Zubairy, a physicist at Texas A&M University, said the Harvard team's achievement was a significant step forward in the emerging area of quantum computing and quantum cryptography.
Quantum cryptography might provide very secure forms of electronic encryption, because the process of eavesdropping on an electronic message would introduce errors in the message, garbling it.
"This would allow you to exchange a key on a public channel, but whereas any classical system can be broken by an eavesdropper, in quantum cryptography you would always find out if someone was looking at your message," Professor Zubairy told BBC News Online.
every time someone uses 'quantum' with computing it makes my head hurt. Lots. |
