Exploration of quantum computer architectures with spins in silicon and diamond

Thomas Schenkel


Quantum computing promises to revolutionize information technology, but it is unclear if large numbers of quantum bits (qubits) can be integrated in any of the many proposed architectures.  Spins of electrons and nuclei of donor atoms in silicon and color centers in diamond are promising candidates for potential large scale integration.  I will give a brief update on the status of our work on the development of quantum computer test structures in silicon and diamond, and discuss recent results on deterministic single atom doping, spin dependent transport in silicon transistors, and coherent information transfer between electrons and nuclei.
