π-Corrected Heisenberg Limit
Researchers have proven that the Heisenberg limit as it is commonly stated is not operationally meaningful, and needs to be corrected by a factor of π.
Evading Heisenberg isn’t easy
Researchers unravel novel dynamics in the interaction between light and mechanical motion with significant implications for quantum measurements designed to evade the influence of the detector in the notorious ‘back action limit’ problem.
