LEMONT, Illinois, August 25, 2021 – Three Argonne National Laboratory projects have received funding from the U.S. Department of Energy to lay the groundwork for breakthroughs in quantum information science. The awards are part of a $ 61 million investment in quantum science and engineering.
Using resources from the Center for Nanoscale Materials (CNM) in Argonne, a team of researchers led by Jianguo Wen will develop a microscope to enable visualization of single-atom-sized quantum emitters, or a few nanometers in diameter. This will allow researchers to accurately measure the characteristics of an emitter and optimize it for quantum networks. The tool, the Quantum Emitter Electron Nanomaterial Microscope, or QuEEN-M, combines recent developments in electron beam pulse generators to create new capabilities that can be applied to a wide range of scientific and technical problems in science. of quantum information.
A team of researchers led by Jeffrey Guest will develop the Atomic Quantum Information Surface Science (AQuISS) laboratory to better understand and control defects near the surface of crystals, associated with the storage of quantum information through the spin property. The creation of the laboratory will allow the team to learn how to manipulate surface spin sites to better preserve and manipulate quantum information. The team will also seek to develop new materials and spins on crystalline surfaces, improving them for the storage and processing of quantum information.
Reliable and scalable information distribution in quantum networks
Argonne scientist Martin Suchara and his colleagues at the University of Chicago and the University of Illinois at Urbana-Champaign will design a quantum Internet protocol that handles different types of quantum information encoding. They will also examine how quantum states are transformed from one type to another inside a quantum network with multiple senders and recipients. Their studies will allow them to improve the flow of information through a network, using the Argonne quantum network as a test site.
