B Quantum entanglement and communications

[ElliotSmith]

TL;DR Summary

Could quantum entanglement be used to send faster-than-light communications across the cosmos?

Could quantum entanglement be used to send faster-than-light communications across vast distances in space, in the distant future?

For example, if humans establish permanent colonies on Mars, it would take some time to send communications between Earth and Mars.

Could a future technology exploit quantum mechanics to send these communications back-and-forth instantaneously or almost instantaneously?
