Scientists develop device for portable, ultra-precise clocks and quantum sensors


National Physical Laboratory
9 May 2013 Strathclyde - In a joint project between the Universities of Strathclyde and Glasgow, Imperial College London and the National Physical Laboratory, researchers have developed a portable way to produce ultracold atoms for quantum technology and quantum information processing. Their research has been published in the journalNature Nanotechnology, where it is featured on the front cover.

Many of the most accurate measurement devices, including atomic clocks, work by observing how atoms transfer between individual quantum states. The highest precision is obtained with long observation times, often using slow-moving ultracold atoms prepared in a large apparatus.

Dr. Aidan Arnold, a Lecturer in Strathclyde's Department of Physics, stated: "The longer the transition of atoms can be observed, the more precisely they can be measured. It is possible to shine laser light on atoms to slow them down using the Doppler effect. We can now do this in a really small device."

The researchers have developed technology which is far more compact than previous setups but can still cool and trap large numbers of atoms for use in portable devices. They pattern the surface of a semiconductor chip to form a diffraction grating, splitting a laser into many beams that cool the atoms.

Professor Ed Hinds, who directs the Centre for Cold Matter at Imperial College London, stated: "These specially micro-fabricated diffraction gratings create the perfect laser beams for trapping and cooling atoms."

Portable clocks, magnetometers and accelerometers have wide-ranging applications, including navigation on earth and in space, telecomunications, geological exploration, and medical imaging.

Dr. Alastair Sinclair, Principal Scientist at the National Physical Laboratory, stated: "The miniaturisation of atomic sensors using these optical gratings can make an important contribution to metrology and high-precision measurement."

Professor Charlie Ironside of the School of Engineering at the University of Glasgow stated: "The specialized optical diffraction gratings were co-designed by the groups in the collaboration and some of them were microfabricated in the James Watt Nanofabrication Centre at the University of Glasgow - the work is a good example of how a team of physicists and engineers can collaborate to produce cutting edge technology."

The project was funded by the Engineering and Physical Sciences Research Council, ESA, the EU AQUTE project, the Wellcome Trust, the UK National Measurement Office, the Royal Society of Edinburgh and the Royal Society.
