Jeremy Levy, Hrvoje Petek, and their team recently received a five-year, $7.5 million grant from the Office of Naval Research’s Multidisciplinary University Research Initiative (MURI) to develop a new type of quantum memory for quantum computers. 

Quantum computers can be built using many different approaches, one of which involves using the spin of electrons to create quantum bits. In turn, these quantum bits can be used to create quantum computers and other quantum information processing capabilities. The challenge lies in containing these electrons. 

The team aims to use exceptionally thin strips of carbon called graphene nanoribbons to trap individual electrons in its honeycomb-like structure and harness their intrinsic spin to store and manipulate quantum information. Only one or two nanometers wide, the graphene nanoribbons will be created using synthetic methods based on self-assembling molecular building blocks.

Congrats Jeremy and Hrvoje!
