This textbook introduces quantum computing to readers who do not have much background in linear algebra. The author targets undergraduate and master students, as well as non-CS and non-EE students who are willing to spend about 60 -90 hours seriously learning quantum computing. Readers will be able to write their program to simulate quantum computing algorithms and run on real quantum computers on IBM-Q. Moreover, unlike the books that only give superficial, “hand-waving” explanations, this book uses exact formalism so readers can continue to pursue more advanced topics based on what they learn from this book.

• Encourages students to embrace uncertainty over the daily classical experience, when encountering quantum phenomena;


• Uses narrative to start each section with analogies that help students to grasp the critical concept quickly;


• Uses numerical substitutions, accompanied by Python programming and IBM-Q quantum computer programming, as examplesin teaching all critical concepts.
