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.
