A solution to one of the key challenges in the development of quantum technologies has been proposed by University of Sussex physicists¹. In a paper published today (28 October) in Nature Communications, Professor Barry Garraway and colleagues show how to make a new type of flexibly designed microscopic² trap for atoms.

Quantum technology devices, such as high-precision sensors³ and specialised superfast computers, often depend on harnessing the delicate interaction of atoms. However, the methods for trapping these tiny particles are hugely problematic because of the atoms' tendency to interact with their immediate⁴ environment.

The Sussex team, in collaboration⁵ with the University of Strathclyde, have now shown that a new technique involving electromagnetic induction⁶ could be the solution.

Professor Garraway says: "Our findings are significant because future quantum technologies will depend on confining and manipulating cold atoms. The design of those traps is normally extremely complex and involves stringent⁷ requirements for scale and smoothness. Our new approach is simple to implement⁸ using a chip-based technology, which is flexible and very robust⁹.

"This is another step towards the development of new quantum technologies that will revolutionise many aspects of our lives. Already, our researchers in Atomic, Molecular¹⁰ and Optical Physics (AMO) are developing devices that could radically¹¹ change how we measure time, navigate¹² our world, sense our gravitational field and solve seemingly impossible mathematical problems."
