Jones,

I believe that most physicists would bet against the idea that
wave-function collapse, or equivalently, quantum measurements
could increase energy concentration on a macroscopic scale
- unless there is a compensatory entropy increase somewhere else.

So, it may be that some internal quantum coherence must exist, and
must be destroyed during heat release.

Here are a few papers that may be relevant -

"Concentrating Energy by Measurement"

"Ratcheting up energy by means of measurement"
http://arxiv.org/abs/quant-ph/0611163

"Composite quantum systems and environment-induced heating"
http://arxiv.org/abs/1110.1551

"Extracting work from a single heat bath via vanishing quantum coherence"

Vacuums"
