Quantum Computing

Abstract

Given its placement at the end of this book, the reader will surmise that this chapter on quantum computing represents the farthest destination out from planar silicon CMOS along the road to the nano era. This would be a mistaken impression. Quantum computing is not a topic in nanotechnology, although it may eventually benefit from some avenues in nano research. It is not about a new use of quantum effects in transistors, and it is decidedly not of any use in supplementing or enhancing the performance of CMOS logic. At present, it is a technology that is essentially nonexistent.
