Photons can travel faster than light in Caesium gas.
But cant transmit the information Pulse faster.

But another question: if
something cant move faster than light,
you need to be shure, that lenght is fixed.
(1 meter = 1 meter)
But quantum physics state that there is no
definite values before you measure them.

So the distance to by travelled (speed = distance / time)
could at the case of your measuremnt be larger
than 1 meter, thus making the object
move effectively faster than you thought.
