## Books on Quantum computing

There seems to be a problem for authors of books on quantum computing - how much maths do you put in? Books on physics can be written in a non-mathematical way, likewise computing books can concentrate on what can be done with computers rather than the theory. Even books on mathematical ideas can be written for a non-technical audience. But it seems that for quantum computers dealing with devices which have a lot of theory but not a lot of use presents a dilemma for writers.

There are lots of introductory articles about quantum computing on the web. A good place to start would be www.qubit.org . |

### General books

*A shortcut through time* by **George Johnson** gives a non-technical introduction to the subject but I feel the avoidance of maths means that some ideas are not explained as fully as they could be. *Ultimate zero and one : computing at the quantum frontier* by **Colin Williams** goes in the other direction - it seems to have more substance, but also seems to use a lot more mathematics, which will be offputting for many readers. I haven't read *Minds, Machines, and the Multiverse* by **Julian Brown** yet, but it does look like it might achieve a better balance than other books.

### From the horse's mouth...

**Richard Feynman** did some of the early work on quantum computing, and the

*Feynman Lectures on Computation* has a chapter on the subject, as well as other relevant material.

**David Deutsch** has been a leading light in the subject and his

*Fabric of reality* is well worth reading to see how quantum computing fits in with his overall view of the universe.

### Textbooks

*Quantum Computation and Quantum Information* by

**Nielsen** and

**Chuang** is

*the* standard work on quantum computing, and anyone seriously interested in studying the subject should have access to a copy. It is well presented, but is aimed at researchers in the subject and so requires some effort to read. Some people might prefer

*Quantum Computing* by

**Josef Gruska**, which is structured more as a textbook for students.
