  • Publication number: 20260035250
    Abstract: Disclosed are synthetic diamond materials for quantum and optical applications, such as quantum information processing, quantum key distribution, quantum repeaters, and quantum sensing devices, based on spin defects in diamond. This includes methods for synthesizing and treating diamond in order to create spin defects with improved spin coherence and optical emission properties, as well as treating the diamond to eliminate unwanted defects that degrade these properties.
    Type: Application
    Filed: August 12, 2025
    Publication date: February 5, 2026
    Applicants: The Trustees of Princeton University, Element Six Technologies Limited
    Inventors: Nathalie de LEON, Brendon C. ROSE, Ding HUANG, Zi-Huai ZHANG, Alexei M. TYRYSHKIN, Sorawis SANGTAWESIN, Srikanth SRINIVASAN, Matthew Lee MARKHAM, Andrew Mark EDMONDS, Daniel J. TWITCHEN, Stephen A. LYON
