Tracks 1 and 2 are live now — 41 lessons total (27 + 14), completely free. Tracks 3–9 are planned in sequence — each builds directly on the last.
Superposition, entanglement, interference, and your first real circuits — without assuming any prior knowledge.
Complex numbers, vectors, matrices, tensor products, Dirac notation — all from scratch, explained plainly.
Single and multi-qubit gates in full detail. Universal gate sets, circuit composition, QFT, and teleportation from first principles.
Planned after Track 2Deutsch-Jozsa, Grover's search, Shor's factoring, HHL — each derived step by step. Not just "here's how it works" but "here's why you'd invent it."
Planned after Track 3Implement circuits with Qiskit and Cirq. Run algorithms on simulators and real quantum hardware. Turn intuition into executable code.
Planned after Track 4BB84, E91, quantum key distribution, post-quantum standards. Why quantum mechanics makes eavesdropping physically impossible.
Planned after Track 5Why qubits fail, stabiliser codes, the surface code, fault tolerance thresholds. The engineering problem separating today's NISQ devices from useful quantum computers.
Planned after Track 6Superconducting qubits, trapped ions, photonics, spin qubits. How quantum computers are physically built and what limits them.
Planned after Track 7Variational algorithms, quantum machine learning, NISQ applications, open problems. Where the field is today and where it's going.
Planned after Track 8
