Abstract

We perform quantum interference experiments on a single self-assembled\nsemiconductor quantum dot. The presence or absence of a single exciton in the\ndot provides a qubit that we control with femtosecond time resolution. We\ncombine a set of quantum operations to realize the single-qubit Deutsch-Jozsa\nalgorithm. The results show the feasibility of single qubit quantum logic in a\nsemiconductor quantum dot using ultrafast optical control.\n
