A team of physicists say they have found a way to sidestep Heisenberg's uncertainty principle, one of the more troublesome ...

Quantum measurement and uncertainty relations lie at the heart of quantum mechanics, delineating fundamental limits on the precision with which non-commuting observables can be simultaneously ...
