SUMMARY:Electrically controlled spin qubits in coupled quantum dot sys
 tems\, R. G. Herb Condensed Matter Seminar\, Vanita Srinivasa\, UMD
DESCRIPTION:The spins of electrons confined in semiconductor quantum d
 ots represent versatile building blocks for solid-state quantum inform
 ation processing devices. Within these systems\, manipulation via elec
 tric fields enables both rapid control and protection from noise. I wi
 ll describe our theoretical investigations of single-electron and mult
 i-electron quantum dot systems with electrically controllable spin rel
 axation\, highly tunable exchange interactions\, and quantum gates rob
 ust against charge noise. These features yield approaches for rapid si
 ngle-spin initialization as well as for controllably coupling donor el
 ectron spin qubits in silicon.<br>
