Learning about how quantum computers work and their algorithms doesn’t have to be difficult and expensive. There are plenty of great books written on the subject that range from popular to science to extensive text books costing hundreds of dollars.

Learning need not be expensive and can even be for FREE. At QZ we have a Quantum Book list of learning and reference texts to cater a wide audience, but where does that leave potential learners without a budget? We decided to list some of the FREE resources from around that web that can help would be learners understand Quantum Computing.

#### Free Online Books and Lectures in Quantum Computing

As something of a book hound myself I always love print, but there is a certain convenience of online books and resources. One of the best known and widely used is the Qiskit Textbook.

#### Learn Quantum Computation using Qiskit

Qiskit is one of the most established open-source Quantum Frameworks and is supported by many large QC players including IBM.

This open-source textbook in collaboration with IBM Research works as algorithms/computation course supplement based on Qiskit.

#### David Mermin’s Lecture Notes

There are plenty of individuals publishing books and information. But LECTURE NOTES ON QUANTUM COMPUTATION aims to cover the basics from little assumed knowledge. You can download the chapters directly from his site. http://www.lassp.cornell.edu/mermin/qcomp/CS483.html

#### John Preskill’s Lecture Notes

Aimed at quite a high – level so certainly not an introductory guide, but quite readable series that focuses on Information theory. So if you already have some background or introductory knowledge it might be worth considering.

#### Lecture Notes on Quantum Algorithms by Andrew Childs

This is more for advanced readers but is well put together and is over 170 pages long.

#### Free Online Quantum Computing Courses

Online courses and MOOCs are very popular ways to learn. Just look at the success of Stanford’s Machine Learning course which has taken the world by storm. There are also courses in Quantum Computing that can be taken without paying a single cent.

#### Quantum 101: Quantum Computing & Quantum Internet

Most online courses can be audited for FREE, which means unless you want or need a certificate you can simply learn the course materials.

TU Deflt are a famous for their expertise in Quantum Computing and the Quantum Internet.

#### Quantum Computing with Brilliant

Brilliant is a great way to learn about maths and subjects such as Quantum Computing. They have a specialist QC course tailored to help you understand how it works.

Look at the QC course from Brilliant.

### Video Series on Quantum Computing

Some companies involved with Quantum Computing produce education around their products and generally the QC field. Companies such as Microsoft and D-wave produce videos on a variety of QC topics.

#### Quantum Impact with Microsoft

Microsoft have produced a new series that has launched on the YouTube video platform aimed at showcasing what can be done with Quantum Computing.

To see the series, look at the Microsoft Channel.

#### D-wave Quantum Annealing

D-wave are the pioneers of Quantum Computing, specifically Quantum annealing. D-wave have produced a video outlining how Quantum Annealing works.
