A common misconception about entanglement is that the particles are communicating with each other faster than the speed of light, which would go against Einstein's special theory of relativity. Experiments have shown that this is not true, nor can quantum physics be used to send faster-than-light communications. Though scientists still debate

https://www.sciencealert.com/watch-this-is-how-quantum-entanglement-really-works
That means that quantum entanglement is real…but new research also shows that the phenomenon won't allow us to communicate faster than the speed of light, which means it doesn't violate the special theory of relativity. And that, at least, would make Einstein happy.

The theorem is important because, in quantum mechanics, quantum entanglement is an effect by which certain widely separated events can be correlated in ways that, at first glance, suggest the possibility of communication faster-than-light.

In short, quantum tunneling seemed to allow faster-than-light travel, a supposed physical impossibility. "After the Hartman effect, that's when people started to worry," said Steinberg. The discussion spiraled for decades, in part because the tunneling-time question seemed to scratch at some of the most enigmatic aspects of quantum mechanics.

The root misconception is the idea that an entangled particle somehow reacts when its partner is measured. It doesn't. Nothing changes, either faster than light or slower than light. The idea that it reacts is known as the "nonlocal wavefunction collapse" and almost no physicist thinks that it actually happens.

The prospect of faster-than-light (FTL) communications revolves around quantum entanglement, a phenomenon Einstein described as "spooky action at a distance".

The claim that "faster-than-light communication via entanglement is impossible" is precisely that the answer to this is "No." - Bob cannot perform any measurement that would allow him any sort of inference about what Alice did, neither a certain nor a statistical one.

42. Collapsing an entangled pair occurs instantaneously but can never be used to transmit information faster than light. If you have an entangled pair of particles, A and B, making a measurement on some entangled property of A will give you a random result and B will have the complementary result. The key point is that you have no control over

This means that the phenomenon of entanglement, the cause of which we have not been able to solve in quantum physics, does not allow for faster-than-light communication. Remotely influencing a widget by entanglement and using that widget to send instant messages are two different things. So much so that when we say faster-than-light
