The huge amount of processing power created by computer designers has not yet been able to satisfy the desire for speed and computing ability. In 1947, Howard Aiken claimed that only six electronic digital computers would satisfy the computing needs of the United States. Others have made similar inaccurate predictions about the amount of computing power that would satisfy the ever-increasing needs of technology. Of course, Aiken did not take into account the large amounts of data produced by scientific research, the explosion of personal computers, or the appearance of the Internet, which have further driven the need for computing power.

Scientists have already constructed basic quantum computers that can carry out certain calculations. Quantum computers will harness the power of atoms and molecules to achieve memory and processing activities. Quantum computers have the potential to achieve certain controls significantly faster than any silicon-based computer. In this book, the reader will learn the design mechanisms of a quantum computer and just how they will be adapted for the next era of computing.

It is not necessary to go back too far to find the origins of quantum computing, as it was first conceived of less than 30 years ago. On the other hand, classical computers have been used, with many difficulties, for a comparatively long time. Paul Benioff is credited with being the first to apply quantum theory to computers, in 1981, when he posited creating a quantum Turing machine.
