WORLD RACE
Physicists believe quantum computers could outperform classical computers with enormous memory and the ability to solve problems millions of times faster.
Teleportation became one of the hottest topics among physicists in quantum mechanics in the past decade, after the IBM lab in the United States provided theoretical underpinning for the work in 1993. Since then about 40 laboratories globally have been experimenting in this area.
Although teams in California and Denmark were the first to do preliminary work on teleportation, the ANU team of scientists from Australia, Germany, France, China and New Zealand was the first to achieve a successful trial with 100 percent reliability.
The idea is if quantum particles like electrons, ions, and atoms have the same properties, they are essentially the same.
So if the properties of quantum particles making up an object are reproduced in another particle group, there would be a precise duplication of the object, so only information about the particles' properties need be transmitted, not the particles.
The inability to pass the information reliably has been a major stumbling block in past "entanglement" experiments.
ANU team member Warwick Bowen said they first successfully teleported a laser beam on May 23 to their great surprise, and repeated the success time after time in following weeks using their small-car-sized transporter, ironing out certain glitches.
"Even in Star Trek they realize there are problems with teleportation," Bowen told the news conference.
"It is such a complicated experiment that nobody knows whether their particular set-up is going to work until you do it....and it turns out our system is very good."
