Race the Quantum Computer

Find the prize. Then watch quantum find it faster.

One of 16 boxes holds the prize. You'll search the only way a normal computer can — one at a time. Then the quantum computer takes a turn.

1 · Your turn

2 · Quantum's turn

A normal computer can't "see" which box is right — it has to check them one by one. Go ahead, hunt for it.

Checks so far: 0

// The bars are real: Grover amplitude amplification computed live, not faked.
// Grover gives a quadratic (√N) speedup for unstructured search — one of the clearest wins quantum has.
