Quantum computing 
with spins in semiconductors This talk will highlight recent advances related to spin-based quantum information processing from a theoretical perspective, including the impact of new material systems and nanostructures and of electric spin control. We discuss the importance of spin-charge hybridization for spin qubit control and measurement, and present several examples. Recently, electric spin control using synthetic spin-orbit coupling due to magnetic field gradients in combination with the exchange coupling has allowed for electrically controlled one- and two-qubit gates for spins in silicon quantum dots. The valley degeneracy in silicon and other semiconductors offers both challenges and opportunities which will be discussed. An alternative approach to all-electric control of spin qubits consists in the use of multi-spin qubits containing more than one electron, a variety of which will be presented, such as the singlet-triplet, exchange-only, resonant-exchange, and quadrupolar qubits.
