Scientists are capable of measuring the position of an object with unprecedented accuracy, but the Heisenberg uncertainty principle ultimately places a fundamental limit on such measurements (known as the standard quantum limit). Now, however, Caltech researchers have found a way to filter this quantum background “noise” and make measurements that go beyond the limits imposed […]

New uncertainty over uncertainty principle
One of the fundamental tenets of quantum mechanics, Werner Heisenberg’s uncertainty principle, is being challenged by University of Toronto researchers who say that Heisenberg may be incorrect. Their work, involving the use of the “weak measurement technique,” is detailed in the journal Physical Review of Letters. Heisenberg’s uncertainty principle states that it is impossible to […]
