About
A gentle, hands-on introduction to quantum computing for curious readers: school and early university students, teachers, and anyone who has read about qubits in the news and wants to know what is really going on.
It builds the three ideas everything else rests on, superposition, measurement and entanglement, with beam splitters, spinning electrons and coin flips before the mathematics. It then uses them to explain quantum cryptography, quantum gates, teleportation and the first quantum algorithms. Appendices cover the probability and linear algebra you need.
Every chapter ends with activities and exercises. The whole book is free to read online, and so are the answers to the odd-numbered exercises.
