Wake-Nanotech leads international team in development of topological quantum computers

Updated: Oct 23, 2019

Materials created at the WFU Nanotechnology Center are thought to be key to the creation of more stable QuBits.

Topological Systems in 2D

“Transition metal diChalcogenides form the basis of 2D crystals that can be grown into fascinating and highly complex geometries.”

As development of quantum information systems accelerates, the need for new, environmentally robust versions of QuBits, quantum registers, and quantum memory must be imagined. New materials from WFU seem to point toward a possible route to these robust universal quantum machines: topological computation. As described by Wilczek and others, rather than spins, or photon polarization, quantum computational schemes are derived from the accumulation of geometrical phase in a closed topological space. Such schemes are thought to be more robust to higher temperatures, and more error tolerant.


To investigate this idea further, and perhaps apply some unusual topological materials developed by the synthesis group at Wake's Nanocenter, a working group of physicists, chemists, mathematicians, and computer scientists was formed in the fall of 2019. The QUANTUM COMPUTER WORKING GROUP @ WAKE ( was made possible by some small funding from the AFOSR and Streamline Automation - a company that specializes in rocket flight.

International Players

“WFU-Nanotech has strong historical ties with Germany's famed Max-Planck-Institute.”

The team also includes a research group at the University of Erlangen in Southern Germany, MPI and Fraunhofer researchers as well as team members in China are also taking part.

What is so special about the WFU materials?

The materials developed at WFU express not only the topological properties of 2D dichalcogenides, but also an unusual twinning in the otherwise perfectly chiral crystal structure. This twin-plane breaks symmetries in the crystal that leads to a rare form of entanglement between the two halves of the crystal. This two Qubit system is the foundation of the WFU quantum register.
