The successful proposal for one of the prestigious COST network grants, funded by the ESF, was led by UCL's researcher Dr Janet Anders .

The AEGIS experiment at the Antiproton Decelerator , in CERN has been designed to exploit techniques Stephen developed to accelerate antihydrogen atoms in excited states; to transport them and make beams suitable for measurements of the acceleration of antimatter in the Earth's gravitational field.

A key component in high-threshold fault-tolerance schemes is the preparation of magic states, quantum states in a superposition of classical states, that are required to exploit quantum effects. However, the slightest of experimental imperfections results in the preparation of flawed magic states, unsuitable for immediate use in quantum computers.

The group has been investigating the magnetic resonance properties of bismuth-doped silicon, and the potential of such a system as a platform for quantum computing.

Their discussions focus on information theory and Maxwell's demon. News and Events Katherine A Wilson-Heyworth 2012-10-23T15:34:09Z Using a X-ray free-electron laser to probe photo-isomerisation http://www.ucl.ac.uk/phys/news/physics-news-publications/ju_29_06_12 An international team of scientists including UCL's Dr Jonathan Underwood report the first study of UV-induced photoisomerisation probed via core ionisation by the femtosecond LCLS x-ray free-electron laser at SLAC in Stanford, US. They investigated x-ray ionization and fragmentation of the cyclohexadiene-hexatriene system at 850 eV during the ring opening. The key finding is that the ion-fragmentation patterns evolve over a picosecond, reflecting a change in the state of excitation and the molecular geometry: the average kinetic energy per ion fragment and H+-ion count increase as the ring opens and the molecule elongates.

Applications range from surface growth and deposition, to elucidating the details of chemical reactions through controlled collisions.
