Quantum Powerhouse

Learn quantum computing by playing it

Four levels, twenty games, zero slides. Each step links to a live simulation in the arcade; the text tells you what to notice. When you can predict the next game before pressing the button, you've learned the thing.

Level 1

One qubit, honestly

Leave knowing what a state is, what a gate does, and why measurement is a question, not a reading.

  1. 1.
    Gate Mixer — A qubit is an arrow; gates rotate it. Press H twice and watch it come back.
  2. 2.
    π-Pulse Trainer — How a NOT gate is really made — calibration, not magic.
  3. 3.
    Born Casino — Probability is fundamental here. Try to beat it; you can't, and that's the lesson.
  4. 4.
    Measurement Duel — The same state answers Z and X differently. Complementarity, felt.
  5. 5.
    State Match — Fidelity: how close two states are, as a steering skill.

Level 2

Interference — the engine

See why phase, not probability, is the quantum resource.

  1. 1.
    Interference Lab — Two paths, one phase knob, certainty to impossibility. Every algorithm is this.
  2. 2.
    Phase Kickback — The control qubit takes the hit. Deutsch and Grover run on this trick.
  3. 3.
    Bloch Detective — Read gates off a Bloch sphere by eye.

Level 3

Entanglement — no classical story

Experience the thing Einstein called spooky, and measure it.

  1. 1.
    Entanglement Dial — Turn two qubits into one inseparable pair; watch qubit A's purity drop to ½.
  2. 2.
    Entangled Dice — Random each, identical together.
  3. 3.
    CHSH — Beat the Classical Bound — Violate a Bell inequality with your own sampled rounds.
  4. 4.
    Teleportation Walkthrough — Move a state without moving matter — and why it can't beat light.
  5. 5.
    Superdense Coding — Two bits on one qubit, with a pre-shared pair.
  6. 6.
    The Cloning Button — Why copying is forbidden — the theorem that secures QKD.

Level 4

Algorithms, noise, and the fight for survival

Run the famous algorithms and meet the enemy every quantum computer fights.

  1. 1.
    Deutsch's One-Question Oracle — The first quantum speedup, never wrong in one query.
  2. 2.
    Grover Searchlight — Amplitude amplification — and what happens when you over-search.
  3. 3.
    Decoherence Dial — Coherence bleeding into the environment, on a real density matrix.
  4. 4.
    Repetition Rescue — Error correction pays for itself — the road to logical qubits.
  5. 5.
    BB84 — Catch Eve — Physics as security: the eavesdropper leaves fingerprints.
  6. 6.
    Born-Rule Randomness — What a quantum random-number generator actually is.

Then read what it's actually good for — so the hype never gets you.
