Q-World

Think Quantum

The mindset: what is strange, what is not, and how to reason about it.

0 / 4 DONE

The Qubit

Amplitudes, the Bloch sphere, phase — and why n qubits mean 2ⁿ numbers.

0 / 4 DONE

Quantum Gates

Gates as rotations, building new gates from old ones, steering the qubit.

0 / 3 DONE

Interference

Waves, paths and the interferometer — the engine of every quantum speed-up.

0 / 3 DONE

Entanglement

Bell pairs, the game classical physics can’t win, and teleportation.

0 / 4 DONE

Circuits

Read circuit diagrams fluently, then build your own on up to four qubits.

0 / 2 DONE

Quantum Algorithms

Deutsch, Grover and Shor — and an honest map of where quantum really helps.

0 / 4 DONE

Advanced Algorithms & Hardware

Fourier transform, quantum walks, variational algorithms, noise and error correction.

0 / 5 DONE

Quantum Security

The threat, quantum key distribution, post-quantum cryptography, and a migration plan.

0 / 4 DONE

Quantum in the World

What it’s really for, what’s hype, how qubits are built, and where to go next.
