One interesting theory of why a maximum speed of communication (speed of light) exists is that it allows simulating the universe in a distributed way, since it gives you a maximum effect range (light cone), thus you can shard your simulation (of course, you still need to sync neighbor shards).

You can force a particle state to 0 or 1, but this will break the entanglement with the other particle, and the other one will no longer be correlated with yours.

It has been proven mathematically that FTL communication of information using entanglement is impossible (under our current understanding of physics, of course). It's called a "no-go theorem":

You have two particles, A and B, which can be in state 0 or 1.

When you measure particle A, you get random value 0. B is instantaneously set to 1. Or the other way around.

But you can't communicate using this, because you can't control the random value you get, thus there is no way to "modulate" the other end.
