Despite the most remarkable wave of technological inventions, there are definite computational problems that the digital revolution still cannot seem to solve, even though some of these computational problems could be solved by scientific advances. Although conventional computers have doubled in processing speed and power nearly every two years for decades, they still do not appear to be fast eough to solve these enduring problems. In the long run, to solve the world’s most tenacious computing problems competently, we will have to turn to an utterly new and more capable machine: the quantum computer.

Finally, the dissimilarity between a classical computer and a quantum computer is not like the difference between an old car and a new one. Instead, it is like the difference between a horse and a hawk: while one can run, the other can fly. Classical computers and quantum computers certainly have that difference. In this chapter we have taken a careful look at where the key differences lie and have taken a profound plunge into what makes quantum computers unique.
