Spins in diamond
The goal of this project is to develop and verify a process for smooth, flat and high-quality diamond plates with Sn vacancy and 13C nuclei for quantum system using spins in diamond. For high-quality qubit device fabrication with spins in diamond, bonding of diamond on sapphire and SiO2/Si wafers are very important, and to realize this, a smooth and flat diamond plates are required. Also, doping of Sn and 13C nuclei, which act as the spins, should be fabricated in a controlled manner in high-purity single-crystal diamond plates. TUDelft and Fujitsu will provide specifications, process the diamond plates and characterize the material and devices, while Element six will develop smooth, flat diamond plates by polishing and a doping process by CVD growth and/or ion-implantation. The result of this project will be the key ingredient for manufacturing chips for quantum computer and internet using spins in diamond in future.
