Where the article explains it
Every real experiment runs for a finite duration in a real environment, and is a property of an idealized, undecohered state.
The passage around this formula
There is a second honest boundary, and it is about time rather than interpretation. Every real experiment runs for a finite duration in a real environment, and is a property of an idealized, undecohered state. Daine Danielson, Gautam Satishchandran and Robert Wald showed, in a closely related setting, that even a source as gravitationally faint as an ordinary black hole will eventually decohere a spatial superposition through the…
