← ScienceWhich consequence results when quantum entanglement suffers decoherence?
A)Increased measurement error above threshold✓
B)Faster quantum key distribution rates
C)Improved quantum computer gate fidelity
D)Enhanced signal propagation distance
💡 Explanation
Decoherence destroys superposition of entangled particles, because it introduces interaction with the environment degrading the precise correlations, introducing an increased measurement error rather than improving function. Therefore the error elevates, rather than fidelity because environments cannot remain noise free.
