List of connections between physical reality and computation
  • Landauer's principle: There is a minimum energy needed to delete information because of the laws of thermodynamics.

  • Limits of Koomey's law: Because of Landauer's principle, for non-reversible computation there is a limit on number of computations per joule.

  • Margolus–Levitin theorem: Even reversible computing is constrained in number of computations per joule.

  • Bekenstein bound: Entropy in given finite space is limited.

  • Bremermann's limit: Implication of Bekenstein bound is that there is a limit on computational power of a computer.
