Quantum computing, explained for everyone.
Independent study notes for quantum computing and quantum machine learning, written from scratch. Every lesson starts in plain words anyone can follow — then goes as deep as you want, all the way to the real math.
Read the simple version. Every lesson opens with a no-jargon explanation — spinning coins, light switches, real intuition.
Go deeper when ready. Expand the rigorous section for Dirac notation, derivations, and the full mathematical picture.
Test yourself. Quick quizzes with instant feedback, then mark the lesson complete and keep your streak.
