B Quantum entanglement and communications

Click For Summary
Quantum entanglement cannot be used for faster-than-light communication, as established by the quantum no-signaling theorem. This theorem indicates that entangled particles cannot transmit information instantaneously, preventing any form of communication that exceeds the speed of light. While the concept of using quantum mechanics for instantaneous communication is intriguing, current scientific understanding does not support its feasibility. Future technologies may evolve, but they would still be bound by the principles of quantum mechanics. Therefore, communication between distant colonies, like those on Mars, will remain limited by conventional speeds.

TL;DR
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?

Thread 'Angular Momentum Vector and Its Magnitude'

For the quantum state ##|l,m\rangle= |2,0\rangle## the z-component of angular momentum is zero and ##|L^2|=6 \hbar^2##. According to uncertainty it is impossible to determine the values of ##L_x, L_y, L_z## simultaneously. However, we know that ##L_x## and ## L_y##, like ##L_z##, get the values ##(-2,-1,0,1,2) \hbar##. In other words, for the state ##|2,0\rangle## we have ##\vec{L}=(L_x, L_y,0)## with ##L_x## and ## L_y## one of the values ##(-2,-1,0,1,2) \hbar##. But none of these...
