Diamond-based Quantum Information Processing and Communication Project

Projects at the University of California at Santa Barbara will focus on developing new quantum measurement techniques to manipulate and read out single electron spins in diamond. The projects will also focus on the on-chip integration of single electron spins with photonics, for communication. Additionally, the project aims to build a world-class research facility for the creation of synthetic crystal diamond and diamond heterostructure materials and devices. Diamonds fabricated by the team will complement many ongoing research initiatives on campus and around the world, including programs working towards solid-state lighting, nanoelectronics, and atomic-level storage.

Two government funding agencies are putting $6.1 million into a pair of research projects aimed at utilizing diamond for quantum communication processing. UCSB is leading the charge on both efforts, due to dramatic developments in quantum physics in the past decade at the university.

This work relates to work by the company Element Six to get longer coherence times by increasing the Carbon 12 purity of diamond.

The UCSB work will advance quantum computing, quantum communications and spintronics.
