Which effect allows superdense coding using entangled photons?

💡 Explanation

Entanglement allows transmission increase: information encoded jointly collapses during measurement by quantum decoherence. The mechanism is quantum entanglement; because measuring one entangled photon collapses both states, therefore channel capacity is doubled rather than limited by shannon capacity.
