Cryptography Scheme Secured By Quantum Physics
2014-03-12 14:30:34

Centre for Quantum Technologies The way we secure digital transactions could soon change. An international team has demonstrated a form of quantum cryptography that can protect people doing business with others they may not know or trust – a situation encountered often on the internet and in everyday life, for example at a bank's ATM. "Having quantum cryptography to hand is a realistic prospect, I think. I expect that quantum technologies will gradually become integrated with existing...

New Theory May Help Explain Why Nature Is Quantum
2013-05-14 12:41:52

Centre for Quantum Technologies at the National University of Singapore Like small children, scientists are always asking the question 'why?'. One question they've yet to answer is why nature picked quantum physics, in all its weird glory, as a sensible way to behave. Researchers Corsin Pfister and Stephanie Wehner at the Centre for Quantum Technologies at the National University of Singapore tackle this perennial question in a paper published 14 May in Nature Communications. We know...

Griffith Uni researchers lead light breakthrough Research physicists have demonstrated the first device capable of amplifying the information in a single particle of light without adding noise. The research collaboration, involving Griffith University, The University of Queensland and University of Science and Technology of China, was able to amplify the noisy quantum state of a single photon subjected to loss, without adding noise in the process; in fact, their amplification reduced...
