← ScienceWhich outcome is observed when one photon in an entangled pair undergoes polarization measurement?
A)Wavefunction collapse of the other photon✓
B)Frequency shift of entangled photon
C)Decoherence of both entangled pair
D)Momentum change of the measuring apparatus
💡 Explanation
When one photon's polarization is measured, quantum entanglement causes instantaneous wavefunction collapse influencing the state of the other entangled photon due to their correlated quantum states. Therefore, the wavefunction of the other photon collapses, rather than frequency shift, decoherence or momentum change, each requiring different interaction mechanisms.
