Uncertainty not so certain after all
Early formulation of famous physics principle undermined by lab experiments
By Alexandra Witze, 13:38 PM September 13, 2012
Physicists may need to tweak what they think they know about Werner Heisenberg’s famous uncertainty principle.
Measuring light particles doesn’t push them as far into the realm of quantum fuzziness as once thought, new research suggests. The work doesn’t invalidate the principle underlying all of modern quantum theory, but may have implications for supersecure cryptography and other quantum applications.
“The real Heisenberg uncertainty principle is alive and well,” says Lee Rozema, a grad...
