Physicists in Austria and Japan are the first to measure two physical quantities that were used in 1927 by Werner Heisenberg in an early formulation of quantum mechanics – but then abandoned because ...

One of the most often quoted, yet least understood, tenets of physics is the uncertainty principle. Formulated by German physicist Werner Heisenberg in 1927, the rule states that the more precisely ...

Researchers Mitsuyoshi Kamba, Naoki Hara, and Kiyotaka Aikawa of the University of Tokyo have successfully demonstrated ...

In quantum mechanics, the Heisenberg uncertainty principle dictates that the position and speed of an object cannot both be known fully precisely at the same time. Researchers now show that two ...

Uncertainty affects the accuracy with which measurements can be made in quantum physics. To reduce this uncertainty, physicists have learned to "squeeze" certain measurements. Researchers are now ...

A revisiting of Heisenberg's uncertainty principle in the light of modern quantum information theory yields a formulation that takes into account the reduction in uncertainty from the point of view of ...

The continued development of the High Temperature Gas Cooled Reactors (HTGRs) requires verification of HTGR design and safety features with reliable high fidelity physics models and robust, efficient, ...
