Manipulating Single Electrons in Semiconductor Devices for Quantum Computing

Michael Lilly
Sandia National Laboratories

Semiconductor nanoelectronic devices can be combined, or integrated, in a variety of ways to control a single electron and form a qubit. We have focused on silicon devices where the electron is confined on a single donor atom and its spin forms the qubit. Pulsed gate techniques allow spin readout for a single electron. At the end of the readout pulse, the electron is initialized to spin down. We demonstrate spin control by applying pulsed microwaves to coherently rotate the electron spin. Using these techniques, we have measured long spin lifetimes, measured single shot spin readout and recently observed coherent oscillations of a single electron spin. Devices for moving to two-qubits will be discussed at the end of the talk.
