Overview of Spin-Based Quantum Dot Quantum Computation

Abstract

Here we give an overview of the research on spin-based quantum dot quantum computation. In particular, we discuss the conditions for the Heisenberg exchange Hamiltonian to be a satisfactory description of two-electron interaction in a GaAs double dot. We also discuss theoretical issues related to spin relaxation, spin encoding, and spin measurement. A brief account is also given to spin-based quantum computation in SiGe quantum dots and donors in Si.
