Phase velocities can travel faster than the speed of light, but group velocities cannot. Information is contained in the group velocity.

There are experiments, most involving quantum tunneling (dispersion effects), which show that indeed, phase velocities can exceed the speed of light. The issue is that these inherently cannot be used to transmit information.

Of course, layman articles distort the message and this issue is often brought up.

The quantum effect of seperated particles also appears instantaneous regardless of distance, faster than light. Since up/down is binary this would provide information in the same way we code computers.

Am I correct?
