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 ...

What is the meaning of Heisenberg’s analogy? (Courtesy: German Federal Archives) A row has broken out among physicists over an analogy used by Werner Heisenberg in 1927 to make sense of his famous ...

Quantum state diffusion framework makes it possible to characterize quantum measurement in terms of entropy production ...

Today, we can measure the position of an object with unprecedented accuracy, but the uncertainty principle places fundamental limits on our ability to measure. Noise that results from of the quantum ...

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 ...
