Which outcome arises when attempting to use entangled photons for faster-than-light classical communication?

💡 Explanation

When using entangled photons for communication, attempting to extract classical information faster than light fails because while quantum entanglement allows for instantaneous correlations, those observed correlations actually require a classical channel for key agreement. Therefore observed correlations rely on slower classical means, and are not faster, rather than total decoherence or collapse because you still observe the correlation.
