Overview of this book

Quantum computing is making us change the way we think about computers. Quantum bits, a.k.a. qubits, can make it possible to solve problems that would otherwise be intractable with current computing technology. Dancing with Qubits is a quantum computing textbook that starts with an overview of why quantum computing is so different from classical computing and describes several industry use cases where it can have a major impact. From there it moves on to a fuller description of classical computing and the mathematical underpinnings necessary to understand such concepts as superposition, entanglement, and interference. Next up is circuits and algorithms, both basic and more sophisticated. It then nicely moves on to provide a survey of the physics and engineering ideas behind how quantum computing hardware is built. Finally, the book looks to the future and gives you guidance on understanding how further developments will affect you. Really understanding quantum computing requires a lot of math, and this book doesn't shy away from the necessary math concepts you'll need. Each topic is introduced and explained thoroughly, in clear English with helpful examples.

9.4 Arithmetic

In section 2.5, we looked at the rudimentary ideas of doing binary addition via logic gates. We’ll revisit that but see how to do it using quantum gates. Like most such algorithms, researchers have published many papers on optimizing the circuits using methods such as the Quantum Fourier Transform, which we cover in section 10.1. algorithm$addition

Addition

I keep to a straightforward approach to help bridge the gap between classical and quantum versions. The gates we use are simple, and we replace bits with qubits. Instead of 0 and 1, we use |0⟩ and |1⟩, respectively. We call the data input qubits |x and | y, and each is in the state |0⟩ or |1⟩ at any given time. We are essentially mimicking what we would do in the classical case.

If we do not worry about carry-in and carry-out qubits, our circuit looks like
