Method for Including 2D Materials into Quantum Computers

Scientists from Russia and Japan have found a way to stabilize two-dimensional copper oxide (CuO) materials using graphene, according to a study published in the Journal of Physical Chemistry C. Besides being the main candidates for spintronic applications, these materials can also be used in quantum computers.

Oxides and carbides of transition metals have recently joined the family of two-dimensional materials. These new materials are of great interest to scientists because of their unusual rectangular atomic structures, chemical and physical properties, and especially a unique 2-dimensional rectangular copper oxide cell that does not exist in reverse crystalline (3D) form. 2D materials that have become well known recently contain a lattice similar to that of crystals.

A group of scientists from MISiS, RAS Institute of Biochemical Physics (IBCP), Skoltech, and the National Institute of Materials Science (NIMS) in Japan discovered 2-dimensional copper oxide materials with an unusual crystalline structure in two-layer graphene using experimental matrix methods.

Skoltech Senior Research Scientist Alexander Kvashnin said: “Finding that the rectangular braided copper oxide layer can be stable under given conditions is as important as demonstrating that the bonding of copper oxide and graphene nanopore and the formation of a common boundary can result in the formation of small, stable 2-dimensional copper.

Unlike the single layer, the stability of the small copper oxide cluster is largely achieved by the edge effects (boundaries) causing its distortion followed by the destruction of the flat 2D structure. Moreover, we have shown that the bonding of two-layer metal with pure copper, which has never been in the form of a flat cluster, makes the 2D metal layer more stable, ”he explained.
