| Quantum mechanics describes the behaviour of sub-atomic particles. It's a field that was opened up in the early 20th Century.

| The theoretical underpinning was developed in the 1960s by Northern Irish physicist John Stewart Bell. But it was Aspect, Clauser and Zeilinger who then conducted the experiments to show the phenomenon was real and could have practical uses. | The theoretical underpinning was developed in the 1960s by Northern Irish physicist John Stewart Bell.

| "I was always interested in quantum mechanics from the very first moments when I read about it," Prof Zeilinger told BBC News. "And I actually was struck by some of the theoretical predictions because they did not fit the usual intuitions that one might have." | "I was always interested in quantum mechanics from the very first moments when I read about it," Prof Zeilinger told BBC News.

| Two areas of entanglement research are garnering a lot of attention today. One is in quantum computers which promise a leap in the ability to solve complex problems. And the other is in encryption, the secure encoding of information. Exploiting entanglement will make it impossible for a third party to eavesdrop on private communications. | Two areas of entanglement research are garnering a lot of attention today.

| "This is useful for military and banking, etc, in secure communications," John Clauser said. "The biggest application to my knowledge is the Chinese who launched a satellite several years ago that they use for secure communications over thousands of kilometres." | "This is useful for military and banking, etc, in secure communications," John Clauser said.

| Commenting, Prof Tim Spiller from the University of York, UK, said the new laureates were worthy winners who had helped to open up an exciting future. | |
| "Quantum technologies have been pursued significantly in the UK and in many other countries worldwide for the last 10 years. We've known about entanglement for rather longer than that, but the investment has been made over the last 10 years to actually really start to exploit this. And there are now one or two commercial products emerging that you can buy that use various aspects of this quantum feature, and we expect there will be many more in the future," he told BBC News. | "Quantum technologies have been pursued significantly in the UK and in many other countries worldwide for the last 10 years.
