![]() ![]() He has still not brought the product of (del X by del p) to zero and keeps close to the Heisenberg`s value of 1/2 of Planck`s constant value as far as possible. What he had ventured is to find a refined value of polarization states of light in different axis, to minimize errors. There is still no way that you can know accurately the two quantum states simultaneously, is agreed by the researcher Steinberg in the article. This had been beautifully explained by light diffraction rings experiment when light is passed through two adjacent pinholes,where actual travel route of photons through the pinhole number 1 or 2 could not be ascertained. In quantum states (i.e.in infinitesimally small states of matter), classical accurate measurement will not work. That means that if the error in position (x) is less, that is when measured accurately, the corresponding error in momentum (p) measurement increases correspondingly to keep the equation correct. The product of error in observation of both position (x) and momentum (p) measured simultaneously is fixed by an equation of 1/2 of Planck`s constant or even more, in Heisenberg Uncertainty Principle.

However, the experiment shows that the act of measurement doesn’t always cause the uncertainty. There’s still no way that you can know both quantum states accurately at the same time, states Steinberg. In the strongest case, the induced fuzziness was little as half of what is predicted by the principle. ![]() They found that one measurement of one polarization did not always disturb the other state as much as the uncertainty principle predicted. The researchers compared weak measurements with strong measurements multiple times. By Heisenberg’s principle, there’s a limit to the certainty to which both states can be simultaneously known. The polarization state along one plane is intrinsically linked to the polarization along the other. The group didn’t measure position and momentum, but its polarization states. This reveals its position, but imparts energy as well causing it to move.Īephraim Steinberg of the University of Toronto in Canada and his team of researchers have performed measurements of photons and showed that the act of measuring can introduce less uncertainty that is required by Heisenberg’s principle. Heisenberg explains this principle by exposing how a scientist trying to take a photograph of an electron, has to bounce a light particle off its surface. ![]()
