Quantum entanglement and non-locality do not violate the speed of light.
Assuming you have a particled entangled to some other distant particle, there is no measurement that you can make in your particle that can make the other particle behave in a way that would transmit information.
An analogy would be 2 entangled coins, the entangled "condition" says that if one coin is heads the other must be tails, vice versa. You separate the two coins and your coin get tails
However there is no way for the guy on the other coin to know whether his coin is heads, unless you go over there and tell him that you got tails, this act of communicating ur result would obey the speed of light, therefore speed of light is still unbroken
I'm aware of the no-signalling and no-cloning theorems. While the violation of the Bell Inequality may not allow superluminal signalling the hidden variable model (as in the coin allegory allegory) has been conclusively disproven and violation of the bell inequality does require superluminal information transmission.
