← ScienceWhich consequence results when quantum entanglement decoheres in quantum radar?
A)Target indistinguishability from background noise✓
B)Increased radar signal penetration depth
C)Enhanced resolution of complex targets
D)Narrowed bandwidth from frequency shifts
💡 Explanation
Decoherence collapses the entangled state via environmental interaction, causing loss of quantum correlations. Because entanglement enhances signal-to-noise ratio in quantum radar, decoherence makes targets indistinguishable from noise; therefore, the signal gets lost rather than enhancing resolution because entanglement fundamentally increases sensitivity.
