Quantum computing with electron spins in quantum dots

Several topics on the implementation of spin qubits in quantum clots are reviewed. We first provide an introduction to the standard model of quantum computing and the basic criteria for its realization. Other alternative formulations such as measurement-based and adiabatic quantum computing are briefly discussed. We then focus on spin qubits in single and double GaAs electron quantum clots and review recent experimental achievements with respect to initialization, coherent manipulation and readout of the spin states. We extensively discuss the problem of decoherence in tins system, with particular emphasis on its theoretical treatment and possible ways to overcome it.
