The link brings us to an article focused on how another article in Quanta Magazine did not summarize an article in Nature correctly.
Really, the right thing to do is go directly to the Nature article, and read the abstract. If you've been reading things about QM, even as a non-physicist, then you're probably pretty close to understanding the abstract.
Moreover, a quick reading of the Quanta Magazine article makes it seem as though they shifted the focus of the original result from predictability and determinism to instantaneous transitions. (Although I note I haven't had time to read and fully digest the Nature paper.)
From the abstract in Nature:
> The times at which the discontinuous jump transitions occur are reputed to be fundamentally unpredictable. Despite the non-deterministic character of quantum physics, is it possible to know if a quantum jump is about to occur? Here we answer this question affirmatively: we experimentally demonstrate that the jump from the ground state to an excited state of a superconducting artificial three-level atom can be tracked as it follows a predictable ‘flight’, by monitoring the population of an auxiliary energy level coupled to the ground state. The experimental results demonstrate that the evolution of each completed jump is continuous, coherent and deterministic.
