The common example of this is the uncertainty relationship of position and momentum vectors, where information gained via measurement of the state of one of the values will increase the uncertainty of the other. While this is a logical consequence of perturbing a system to attain information about it, Heisenberg's principle takes it to the extreme by suggesting that such uncertainty is not due to our technological methodology of measurement but instead an inherent property of matter and energy. This leads to the Heisenberg-Bohr probabilistic model of quantum mechanics, also known as the Copenhagen interpretation. While being the consensus model of quantum mechanics, it is an interpretation that is infamous for its counter-intuitive, surreal, and inconsistent interpretations of underlying phenomena. Now, a new technique that significantly improves the sensitivity of measurement instruments like magnetic resonance imagers and atomic clocks -- thus requiring less potentially perturbing energy -- are achieving measurements with exquisite precision. The new techniques suggest that Heisenberg's uncertainty may not be an inherent property of the universe, as postulated by the Copenhagen interpretation, but instead a reflection of our technological capacity to measure ultra-small quantum systems.

Sewell, led by ICREA Prof. at ICFO Morgan W. Mitchell. In their article 'Simultaneous tracking of spin angle and amplitude beyond classical limits', published this week in Nature, they describe how a properly designed instrument can almost completely avoid quantum uncertainty."
