Hi Colin,

Energy cost is due to erasure of information only (Landauer principle), and you can compute without erasing anything, as you need to do if you do quantum computation. You might search on Landauer, Bennett, Zurek, and on the Maxwell daemon.

Hi all,
I was wondering if anyone out there knows of any papers that connect computational processes to thermodynamics in some organized fashion. The sort of thing I am looking for would have statements saying

cooling is ....(info/computational equivalent)
pressure is ..(info/computational equivalent)
temperature is ....
volume is ....
entropy is ....

I have found a few but I think I am missing the good stuff.
here's one ...

Reiss, H. 'Thermodynamic-Like Transformations in Information Theory', Journal of Statistical Physics vol. 1, no. 1, 1969. 107-131.

cheers
