Quantum Teleportation
Transfert d'un état quantique à distance via l'intrication, sans transport de matière.
Elle repose sur l'intrication quantique et la transmission d'informations classiques. L'état d'origine est 'détruit' lors de la mesure initiale, garantissant le respect du théorème de no-cloning (impossibilité de copier un état quantique). C'est la base du futur Internet Quantique sécurisé.

📠 A way to send the 'blueprints' of an atom to a new location so perfectly that the atom at the other end becomes the original.

## Protocol Steps
1. Entanglement: Alice and Bob share a Bell pair.
2. Alice's Measure: Alice performs BSM on the unknown state and her qubit.
3. Classical Info: Alice sends 2 bits of result to Bob.
4. Bob's Correction: Bob applies a Pauli gate to restore the state.
