Which outcome enables quantum cryptography protocols when paired photons are distributed?

💡 Explanation

Shared key generation results from quantum key distribution because photon entanglement allows instant correlation, therefore any measurement affecting one photon instantly affects its partner, enabling secure key exchange, rather than only improving transmission range.
