The Connection between Logical and Thermodynamical Irreversibility

  title={The Connection between Logical and Thermodynamical Irreversibility},
  author={Tony Short and James Ladyman and Berry Groisman and Stuart Presnell},
There has recently been a good deal of controversy about Landauer’s Principle, which is often stated as follows: The erasure of one bit of information in a computational device is necessarily accompanied by a generation of kT ln 2 heat. This is often generalised to the claim that any logically irreversible operation cannot be implemented in a thermodynamically reversible way. John Norton (2005) and Owen Maroney (2005) both argue that Landauer’s Principle has not been shown to hold in general… CONTINUE READING
