There was another article about this group's work back in September, at
it seems as though this is not really about contradicting the
mathematical form of uncertainty in the equations of quantum mechanics, but
rather about certain interpretations of uncertainty which say it's all
induced by measurement. As Steinberg says in that article:
'Don't get too excited: the uncertainty principle still stands, says
Steinberg: “In the end, there's no way you can know [both quantum states]
accurately at the same time.” But the experiment shows that the act of
measurement isn't always what causes the uncertainty. “If there's already a
lot of uncertainty in the system, then there doesn't need to be any noise
from the measurement at all,” he says.'
Also see the abstract of a paper by Rozema et al (the main scientist they
quoted in Dan's link) at
"When first taking quantum mechanics courses, students learn about
Heisenberg’s uncertainty principle, which is often presented as a statement
about the intrinsic uncertainty that a quantum system must possess. Yet
Heisenberg originally formulated his principle in terms of the “observer
effect”: a relationship between the precision of a measurement and the
disturbance it creates, as when a photon measures an electron’s position.
Although the former version is rigorously proven, the latter is less
general and—as recently shown—mathematically incorrect."
