← ScienceWhich effect allows superdense coding using entangled photons?
A)Increased channel capacity✓
B)Dispersion reduction
C)Chromatic aberration
D)Nonlinear refraction control
💡 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.
