One problem I see with the experimental setup is that it is impossible to remove the loss of energy from the system. For example, no mirrors are perfectly smooth, perfectly reflective, and perfectly aligned. Even if coherence is formed, it would still be at the cost of heat, so it would be unclear if entropy actually decreases.
Hmm, good thought.
