Quantum Information Storage for over 180 s Using Donor Spins in a 28Si “Semiconductor Vacuum”

John Morton and collaborators in Simon Fraser University and Berlin have made a 'superposition' – the ability of an atom or quantum magnet (spin) to exist in two places at once – last up to three minutes and 12 seconds, over 100 times longer than the record of 1.75 seconds achieved in silicon by the same team in 2008. A report of the research, entitled 'Quantum information storage for over 180 s using donor spins in a 28Si semiconductor vacuum', is published in Science on 8 June 2012 at http://dx.doi.org/10.1126/science.1217635 Also see Oxford University news item

Manufacturing the future: endohedral fullerenes, small molecules, big challenges
Dr Kyriakos Porfyrakis has been awarded an EPSRC Fellowship to explore the manufacturing capacity and chemical functionalization of endohedral fullerenes. The grant, worth £1.5M over 5 years, will allow Kyriakos to develop manufacturing methods for large-scale production of a variety of endohedral fullerenes.
