According to Asher Peres citation and David Kaiser, citation the publication of the no-cloning theorem was prompted by a proposal of Nick Herbert citation for a superluminal communication device using quantum entanglement. Source: Internet

All forms of energy are believed to interact at least gravitationally, and many authors state that superluminal propagation in Lorentz invariant theories always leads to causal paradoxes. Source: Internet

Because the group velocity for such a field is superluminal, naively it appears that its excitations propagate faster than light. Source: Internet

By contrast, tachyonic fields - quantum fields with imaginary mass - certainly do exist, and exhibit superluminal group velocity under some circumstances. Source: Internet

However, it is not the group velocity but the signal velocity that determines the communication speed, and superluminal group velocity does not imply superluminal signal velocity. Source: Internet

However, it was quickly understood that the superluminal group velocity does not correspond to the speed of propagation of any localized excitation (like a particle). Source: Internet
