Scientists prove particles in a quantum system can be rejuvenated

“ Navascués said, “If you want a system to age 10 years, it will take 10 years. You can’t create time out of nothing. To make a system age 10 years in one year, you must get the other nine years from somewhere.” Using this logic, the scientific team hit upon a trick to speed up time. “We discovered that you can transfer evolutionary time between identical physical systems. In a year-long experiment with 10 systems, you can steal one year from each of the first nine systems and give them all to the tenth. At the end of the year, the tenth system will have aged 10 years; the other nine will remain the same as when the experiment began.”

Just leaving it right there

“you can run it without knowing about the system, its internal dynamics, or even the details of the interaction between the system and the experimenter.”

The scientific meta right now seems to almost contradict itself in the english language. Is there any tool/book out there that could help me understand quantum dynamics and its limitation better?

I'm having trouble understanding how the proof of this is supposed to look like.

It seems like this should have implications for quantum cryptography. Does anyone have any references to work on such implications?

Enhorabuena .
