Q5) pico-electronics Tbps data rates THz CPU? Q5) pico-electronics, Tbps data rates, THz CPU?

A) YES and it all depends on:

possible to engineer at:- device level (clever device structure & nano- fabrication to limit degrees of freedom)- meterial level (solid-state)

State-of-the-art:electronics: GHz commercially available, THz in active research

photonics: femto-second (20 fs) commercially available, atto-second (as) in active research.

S Kanjanachuchai

note: GHz = 1/ns, THz = 1/ps
