Quantum information process with nanometre precession ion implantation — •Inam Mirza — 3. Physikalisches Institut Universität Stuttgart

The spin state of a single nitrogen-vacancy centre in diamond is one of the most attractive candidate for quantum information processing because of its long spin coherence time [1]. Further more coupling (magnetic dipole) between the spins are required for scalable quantum computing (2-qbit operation) [2]. This process requires a high implantation positioning accuracy and nitrogen free clean diamond (<0.1 ppm nitrogen concentration). Here we report recent progress towards single ion implantation within nanometre scale accuracies.
