← ScienceWhich outcome is observed when one photon of an entangled pair passes through a polarizer filter?
A)The second photon polarisation randomizes.
B)The second photon polarisation is instantly known.✓
C)The entanglement is immediately broken.
D)The second photon is annihilated instantly.
💡 Explanation
When one entangled photon passes through a polarization filter, wavefunction collapse causes the other entangled photon's polarization state to be instantly known, maintaining correlation due to the prior quantum entanglement. Therefore its polarization reveals itself, rather than randomization, breakage or annihilation, processes without requiring prior wave function overlap.
