Coherent spin transfer in semiconductor quantum circuits
Abstract Invited
To interconnect different nodes of a spin-based quantum processors, one of the options is to be able to displace individual electrons within semiconductor nanostructures while keeping the spin coherence. We will discuss several strategies to realize such a functionality within AlGaAs heterostructures and their experimental implementations. We will demonstrate how the charge, the spin and the coherence of individual electron spins can be preserved along the displacement. Finally, we will discuss the different mechanisms that are observed to limit the length over which classical and quantum information can be transferred.
