Which consequence results when two entangled photons pass optical fibers under differential stress?

A)Polarization correlation degrades significantly✓

B)Refractive index becomes isotropic

C)Phase coherence becomes entirely constructive

D)Group velocity dispersion becomes negligible

💡 Explanation

Differential stress alters each fiber's refractive index, causing varying propagation delays and polarization changes. Because Quantum decoherence degrades the original quantum entanglement; therefore, polarization correlation decreases, rather than changes in optical isotropy or fiber dispersion.
