Phys.org has reported:

A study examines how imposed randomness interacts with environmental effects in random quantum systems. The source illustrates the problem with a deck of cards being shuffled while some cards fade through contact with the external environment.

The comparison frames the research as an effort to determine how the way the cards are shuffled relates to their fading as they are exposed to their surroundings. The source provides no researchers’ names, publication date, location, numerical findings or next steps.
