University of California, Santa Barbara (UCSB) scientists say that diamonds could revolutionize quantum mechanics in computing by enabling ultra-secure communications, super-fast database searches, and unprecedented code-breaking capabilities. The U.S. Defense Advanced Research Projects Agency and the U.S. Air Force Office of Scientific Research have provided $6.1 million for a pair of UCSB-led research projects that are focused on using diamonds for quantum computing processing. "This vital support offers extraordinary collaborative research opportunities for students to engage at the frontiers of the field in areas spanning fundamental physics to materials science," said David Awschalom, principal investigator for both projects and professor of physics and electrical and computer engineering at UCSB.
The funding will be used for a research effort that includes CNSI, Hewlett-Packard Research Labs, and a team of faculty from Lawrence Berkeley National Laboratory, Harvard University, the Massachusetts Institute of Technology, the University of Iowa, and Delft University of Technology. The projects will attempt to develop new quantum measurement techniques that manipulate and read out single electron spins in diamonds, and will focus on the on-chip integration of single electron spins with photonics for communication. The funding also will support the building of a research facility for the creation of synthetic crystal diamond and diamond heterostructure materials and devices. Diamonds fabricated by the scientists will complement several ongoing research efforts both on UCSB's campus and around the world, including efforts that focus on solid-state lighting, nanoelectronics, and atomic-level storage.
