@Demystifier so conservation of energy could be violated at small microscopic scale due to uncertainty principle. Did I get it right?

It's not that simple.

It points out that the standard conservation law is only a statistical law, which, by itself, is not sufficient to understand conservation of energy at the individual level.

The experiment described in the paper depended on the opening timing (the box was open only for a time T), but they didn't talk about uncertainty relation ΔTΔE:

Am I missing something here?

One can talk about ΔE without talking about ΔT.

One can talk about ΔE without talking about ΔT.

One must talk about ΔE when talking about T.
