← ScienceWhich outcome compromises quantum key distribution during data transmission?
A)Environmental decoherence alters entangled states.✓
B)Detector inefficiency skews entanglement.
C)Polarization drift disrupts photon arrival.
D)Dispersion broadens transmitted pulse signals.
💡 Explanation
Environmental decoherence erodes the quantum link because, the correlation from quantum entanglement suffers state degradation leading to errors, therefore compromising the security and integrity of the key, rather than signal degradation from dispersion.
