Scientists at the University of Copenhagen have developed a hands-on answer to a challenge linked to Heisenberg's Uncertainty Principle. The researchers used laser light to link caesium atoms and a vibrating membrane. The research, the first of its kind, points to sensors capable of measuring movement with unseen precision.

 

In a scientific report published in this week's issue of Nature, NBI researchers demonstrate that Heisenberg's Uncertainty Principle can be neutralized to some degree.

I understood the quantum back action to be a separate phenomenon from the HUP. QBA is a measurement phenomenon, and HUP is inherent.
