Updated: I added the aha-chapter that I was missing.
"Quantum computers try all possibilities in parallel" is the popular line — and it's dangerously misleading. A measurement collapses everything to one random answer, so "parallel" on its own is useless.
The actual move: a quantum algorithm is ONE global linear transformation on a 2^n-amplitude vector, designed so wrong answers destructively cancel and the right one amplifies. Classical searches. Quantum shapes.
Walkthrough with a Grover-style bar chart in four snapshots, plus the full pipeline: superconducting oscillator → Josephson junction → Bell state → amplitude amplification → Shor / Grover / simulation.

L'informatique quantique, basée sur la contre-intuitive mécanique quantique, diffère profondément de l'informatique classique.
Tania Belabbas, de l'Institut quantique - Université de Sherbrooke, fait appel aux mathématiques pour nous expliquer le fameux qubit.
