I've written two books on quantum computing with pictures:
Picturing Quantum Processes: A First Course in Quantum Theory and Diagrammatic Reasoning
With Bob Coecke. Introducing the basics of quantum theory and quantum computing from scratch, purely using diagrams...and dodos!
Picturing Quantum Software: An Introduction to the ZX-Calculus and Quantum Compilation
With John van de Wetering. A guide to state-of-the art techniques in quantum circuit optimisation, classical simulation, and error correction, using the intuitive graphical language of the ZX Calculus.
Get it for free on Github.
If you aren't quite ready for those yet, check out this book and Youtube channel, by some friends of mine:
Quantum in Pictures: A New Way to Understand the Quantum World
By Bob Coecke and Stefano Gogioso. A simple, friendly, and novel way to explain the magical world of quantum theory. Using pictures alone, this book will equip you with the tools you need to understand the quantum world including recent developments in quantum computing.
If you are interested in the ZX-calculus for quantum computing, the best place to start is zxcalculus.com. If you also like coding, head over to zxcalc on Github.
