New 'Double Slit' Experiment Skirts Uncertainty Principle
In the classic double-slit experiment, first done more than 200 years ago, light waves passing through two parallel slits create a characteristic pattern of light and dark patches on a screen ...
Double-slit experiment
The double-slit experiment (and its variations) has become a classic for its clarity in expressing the central puzzles of quantum mechanics. ... pointed out that there is in fact no conflict between the weak measurements performed in this variant of the double-slit experiment and the Heisenberg uncertainty principle. Weak measurement followed ...
Quantum Mechanics and the Famous Double-slit Experiment
However, before we can understand how this is possible, we first need to know how Heisenberg's uncertainty principle accounts for wave-particle duality in the double-slit experiment. The Double-Slit Experiment. The double-slit experiment is famous because it provides an unequivocal demonstration that light behaves like a wave. But the ...
Quantum physics experiment shows Heisenberg was right about uncertainty
The two-slit experiment In this type of experiment there is a barrier with two holes or slits. We also have a quantum particle with a position uncertainty large enough to cover both slits if it is ...
double slit experiment
When observing which slit a particle goes through in the double slit experiment, high momentum uncertainty causes diffraction. We see two overlapping single-slit diffraction patterns without interference fringes, as the wave function collapses, eliminating the interference seen when both slits are unobserved.
Why doesn't the double-slit experiment violate the uncertainty principle?
In the double-slit experiment, when an electron reaches the detector after passing through the holes, it has a certain momentum which we can measure with arbitrary accuracy. ... heisenberg-uncertainty-principle; double-slit-experiment; Share.

The Uncertainty Principle
The beam spreads out a bit, but if we interpose a sheet of metal with a slit of width w, then for particles that make it through the slit, we know y with an uncertainty Δ y = w. Now, if the slit is a long way downstream from the electron gun source, we also know p y very accurately as the electron reaches the slit, because to make it to the ...

quantum mechanics
The uncertainty principle says that we cannot measure x x and p p simultaneously. One way this is reflected in formalism of quantum mechanics is that we can talk about the quantum state by giving ψ(x) ψ (x) OR by giving ϕ(p) ϕ (p); these two functions are not independent (either one suffices to fully determine the quantum state).
Finally making sense of the double-slit experiment
This way, within a double-slit experiment, the particle goes only through one of the slits. In addition, a nonlocal property originating from the other distant slit has been affected through the Heisenberg equations of motion. Under the assumption of nonlocality, uncertainty turns out to be crucial to preserve causality.
