Physical Principles & Dynamic Phase Contraction
In 1961, Rolf Landauer demonstrated that erasing or changing one bit of information in a non-reversible system fundamentally dissipates a minimum entropy quantity of energy:
E_min = k_B · T · ln(2)In deep-submicron process nodes (such as 2nm Gate-All-Around field effect transistors), standard FP16 operations discard high amounts of intermediate bit states, creating massive thermal dissipation. By quantizing down to INT8 or INT4, or leveraging Reversible Phase Contraction (where microstates are topologically preserved without information loss), total switching dissipation dramatically approaches the fundamental Landauer limit.
