Physicists Show How Quantum Uncertainty Sharpens Measurements | Quanta Magazine
Throwing out data seems to make measurements of distances and angles more precise. The reason why has been traced to Heisenberg’s uncertainty principle.
Hasnain says:
“Recently, Yunger Halpern and other theorists showed that Kirkwood-Dirac negativity also underlies quantum behavior in contexts besides metrology, including quantum thermodynamics and fast information scrambling in black holes. The researchers say that bridges between these domains could foster further insights, or metrological advantages.”
