BATON ROUGE – Many of today’s technologies rely on the interaction of matter and energy at extremely small scales. Quantum mechanics studies nature at such scales — at least a million times smaller than the width of a human hair. Technology companies are in a race to develop the first quantum computer that experts say will transform the digital world as we know it today. Not only will today’s computers become obsolete but so will Internet privacy and security systems. LSU Department of Physics & Astronomy Professor and Hearne Chair of Theoretical Physics Jonathan Dowling is a leading expert in quantum technologies. This week, the National Science Foundation, or NSF, awarded him and colleagues a multi-million dollar grant to develop ways to share quantum information through photonic integrated circuits, which encode information on light rather than electricity. The scientists will create a single photonic integrated circuit chip for much more secure quantum communications and computation than is currently available. Dowling’s work could significantly improve data encryption for personal privacy in quantum computing.

“At LSU, my students and I will work on a protocol for quantum teleportation. In any quantum network, such as a quantum computing architecture or a distributed quantum Internet, the most resource efficient method to move quantum data around is to teleport it,” Dowling said.

He and his students at LSU will analyze quantum computer and quantum networks and put bounds on the rate and efficiency of data transfer.

“The quantum revolution is about expanding the definition of what’s possible for the technology of tomorrow," said NSF Director France Córdova. “NSF-supported researchers are working to deepen our understanding of quantum mechanics and apply that knowledge to create world-changing applications. These new investments will position the U.S. to be a global leader in quantum research and development and help train the next generation of quantum researchers.”

Dowling and colleagues from University of Colorado – Boulder, University of Texas Austin and the University of Virginia are among those awarded by NSF for fundamental quantum research aimed to enable the U.S. to lead a new quantum technology revolution.
