Perimeter Institute researchers highlight the potential use of graphene in future quantum information technologies.

July 3, 2014, Waterloo, Ontario, Canada – Researchers from Perimeter Institute for Theoretical Physics (PI) have found a potential link between graphene and the development of quantum computers. The research, conducted by an international team including PI Faculty member Dmitry (Dima) Abanin and postdoctoral researcher Zlatko Papić, was published in Science on July 3, 2014.

Whereas the three-dimensional world has two classes of fundamental particles – fermions and bosons – the two-dimensional world of graphene, a material that is only one atom thick, is a realm of quasiparticles called anyons. If these anyons are what’s known as “non-Abelian” (as the new theory indicates they should be), they might be used in the making of qubits – the bits of information processed by a quantum computer.

The remarkable promise of quantum computers – powerful processers that, by capitalizing on uniquely quantum phenomena, vastly outperform their classical counterparts at important tasks – will hinge on the development of a new breed of hardware. According to the new theoretical work, graphene may become a crucial piece of that puzzle.

While this new work is still a step away from experimental proof, it is an indication that graphene may have a very important role to play in the development of quantum computers and related technologies.

Institut Périmètre de Physique Théorique

L'Institut Périmètre est le plus grand centre de recherche en physique théorique au monde. Fondé en 1999, cet institut indépendant vise à favoriser les percées dans la compréhension fondamentale de notre univers, des plus infimes particules au cosmos tout entier. Les recherches effectuées à l’Institut Périmètre reposent sur l'idée que la science fondamentale fait progresser le savoir humain et catalyse l'innovation, et que la physique théorique d'aujourd'hui est la technologie de demain. Situé dans la région de Waterloo, cet établissement sans but lucratif met de l'avant un partenariat public-privé unique en son genre avec entre autres les gouvernements de l'Ontario et du Canada. Il facilite la recherche de pointe, forme la prochaine génération de pionniers de la science et communique le pouvoir de la physique grâce à des programmes primés d'éducation et de vulgarisation.
