The spin, is predicted to be a good candidate for quantum bits. Advances in semiconductor quantum dot technology have enabled us to detect and coherently manipulate the single electron spin. However, for quantum computation the one-qubit operation is not sufficient. In addition an entangling two-qubit operation is necessary.
In this colloquium I will provide an overview about the progress of spin based quantum computation with quantum dots. After a description of various spin qubit designs and recent advances in this field, I will introduce our work. Here, we show that an entangling two-qubit operation can be achieved by using a double quantum dot with a split micro-magnet design. The results are highly important to achieve the universal set of quantum operations necessary for quantum computation.
