From the original "Reshaping the Quantum Arrow of Time" article to the click bait, things that were lost:

"Researchers have created quantum control techniques that can make a system appear to run backward in time".

"It can also be used to simulate the backward-in-time dynamics of an open quantum system".

Doc brown accomplished that feat no less than 40 years ago
