Quantum computing overhauls computer science. Designing life-saving drugs and solving super-large logistics problems that are difficult or impossible for classical computers to handle are now within reach. Instead of iterating through each possible configuration one by one, quantum computing speeds up the search by giving you the tools to examine all possibilities simultaneously to find those that work. Now you can work with real quantum computers instead of just talking about them theoretically.

Discover a new visual way of looking at quantum bits that makes quantum computing intuitive for computer programmers. Master the special properties that make them different, and more powerful, than classical bits. Control quantum bits with gates and create circuits to model complex problems. Write programs that run on real quantum machines to solve problems that classical computers struggle with. Dive into quantum optimization and cryptography.

Get a head start on the technology that will drive computer science into the future.
