Quantum teleportation over 16 km in open air

News: Communications    May 20, 2010
Quantum teleportation is not the easiest concept to understand, much less believe. Teleportation sounds like something out of Star Trek. It’s not; this is real. In what promises to be a milestone experiment led by Jian-Wei Pan and Cheng-Zhi Peng at the University of Science and Technology of China and Tsinghua University (Beijing, China), quantum [...]

A big step up: Two qubit computing

News: Computer Power    December 22, 2009
Step by step we’re moving closer to useful quantum computing. A big step, announced by the National Institute of Standards and Technology (NIST, USA), was the demonstration of a computing device using two qubits. Previous demonstrations by various researchers have used one qubit. In computing, two computational units are far more powerful than one. This [...]

Quantum computing and image recognition

Impact: Computer Power    December 14, 2009
One of the many things that’s easy for (adult) humans and very difficult for computers is image recognition. Take twenty thousand pictures of a street, half with cars and half without. A human being will separate car pictures from non-car pictures with about 100% accuracy (if not falling asleep from boredom). Not so for computers, [...]
