How a quantum computer finds the answer, in two qubits

Quantum computers don't try every answer at once. They cancel the wrong ones.

Two qubits give four answers a weight each. One gate flips the hidden answer below zero. Another mirrors every weight across the average, so the wrong three land on zero and the right one takes it all. Measure it and you get the answer every time.

Send it to whoever told you it tries everything in parallel.
