faster than light 3

[GOTWW]

It is a commonly taught that the phase velocity propogates at a velocity > the speed of light in waveguide systems. However, with the caviot that the information travels at the "group velocity", which is equal to or slower that the speed of light.

Question? by using multiple channels or waveguides, quantum detection and combinational logic, could an effective information "packet" be synthesised from the combination of phase velocity transmitted energy? and faster than the conventional group velocity.

The application is be encription keys that are imbedded into leading edges of com signals.

Just another twist on the laser light spot.
Instead of a light beam use a hypothetical wire or string.
Makes Nbucska's experiment very correct.
