I also figured that they meant entangled with some system that can mark change, but change is only possible with a concept of time. So I still don’t follow.
I think they mean that a quantum system entangled with another quantum system serving as a clock will create the appearance of classical physics including classical notions of time in the system when you observe it from a macro scale?
That way this theory tries to bridge the gap between quantum notions of spacetime and classical notions of space and time?
If that’s not what it is then it’s beyond me what they’re trying to say.

Science article writers try not to fudge over lack of understanding of physics by writing “quantum” over everything challenge: level - impossible.
