Quantum computing in silicon

Abstract

Down-scaling has been the leading paradigm of the semiconductor industry since the invention of the first transistor in 1947. This paper discusses the development of a unique technology for creating atomic-scale devices in silicon. We will introduce single atom transistors and how we are systematically demonstrating the components of a quantum integrated circuit at the atomic-scale towards the development of a silicon based quantum computer. This new type of computer exploits the laws of quantum physics to provide a predicted exponential speed up in computational processing power.
