Physics breakthrough should solve quantum computing's dead cat problem

I'm not going to go through and analyze the undoubtedly dense original research, but if the click-baitey headline is correct, this does seem like a huge jump in our grasp on reality.

From how long have we thought that quantum particle's "leaps" were random, and part of the inherent unpredictability of quantum reality? How long has popular culture around "quantum randomness" been ingrained in our inner imaginations of how the world worked?

This could be the start of something new.
