Quantum Technology and the Tachyons 

 

Quantum field theory (QFT) is the quantum theory of fields. It provides a theoretical framework, widely used in particle physics and condensed matter physics, in which to formulate consistent quantum theories of many-particle systems, especially in situations where particles may be created and destroyed.

Since a tachyon moves faster than the speed of light, we can not see it approaching. After a tachyon has passed nearby, we would be able to see two images of it, appearing and departing in opposite directions. The black line is the shock wave of Cherenkov radiation, shown only in one moment of time.

Tachyon

A tachyon (from the Greek ταχύς (takhús), meaning "swift, fast") is any hypothetical particle that travels at superluminal velocity. The first description of tachyons is attributed to German physicist Arnold Sommerfeld, but it was George Sudarshan, Olexa-Myron Bilaniuk and Gerald Feinberg (who originally coined the term) in the 1960s who advanced a theoretical framework for their study. A tachyon is constrained to the space-like portion of the energy-momentum graph. Therefore, it can never slow to light speed or below. To date, the existence of tachyons has been neither confirmed nor explicitly ruled out. Since the existence of tachyons poses possibly irreconcilable theoretical difficulties and incompatibilities, tachyons may be considered unphysical, and a physical theory may be considered ruined if it contains a tachyonic field. In some cases the theory can be repaired, and the tachyons removed, via tachyon condensation. (Source: Wikipedia)
