Bismuth donor Spins in Silicon for Quantum Computing

Our research group is expert in Hybrid Quantum Devices where spins in solids are coupled to superconducting quantum circuits. We use these devices for quantum computing applications; in particular we develop spin-based quantum memories for microwave photons. For this application, we need implantation of Bismuth atoms in a silicon substrate. The Bismuth atoms when cooled at low temperature form donors, whose electron spin has a very long coherence time. Therefore, in this project, we will provide silicon substrates (isotopically enriched in the nuclear-spin-free Si28 isotope), and we request implantation of bismuth ions from Rubion.
