Oxford University team takes a quantum leap

25 January 2010
A team at Oxford University has used a quantum computer to calculate the precise energy of molecular hydrogen, in a move which is being hailed as a breakthrough for modern science and industry.

Reported in Nature Chemistry, the development is being touted as the first step on the road to a new quantum system, which could have significant implications for a range of applications, as well as expanding the field of human knowledge.

Quantum computing is designed to focus on machinations which are typically unnoticeable in our day-to-day lives but which have a significant bearing on human life.

The latest developments from the Oxford scientists could hold the key to modelling and understanding how some of these processes work.

Speaking to the Oxford science blog, Jacob Biamonte, who is based with the university's Computing Laboratory and helped author the paper, revealed how these 'quantum simulations' could influence research and wider society.

"A future quantum simulator will help us understand the nature of matter - particularly chemical reactions - by finally providing solutions to long standing problems that we simply have been unable to solve using even the world's largest classical computers," he explained.

The key future development, he added, would be the realisation of an "intractable chemical simulation", such as the ground state of a caffeine molecule.

"This represents a step forward that is difficult to imagine," he continued. "What if we did not know how to control electricity, but had blueprints for iPhones, electric motors and dishwashers? Material Scientists and Quantum Chemists are in this situation!

"The impact a quantum simulator will have on this world is as difficult to imagine as an iPhone would have been in the Dark Ages."

Oxford is at the centre of some of the UK's most sophisticated scientific experiments, with the region combining the latest innovations with the commercial infrastructure capable of developing it.

A number of companies have close links with the university, which has seen a wide range of ideas brought out of the laboratory and into the real world - although few have the dizzying potential being described in quantum simulators.ADNFCR-1584-ID-19574605-ADNFCR
