Molecules can be in two places at the same time

Quantum mechanicsrepresents the most mysterious and poorly understood branch of physics, has repeatedly surprised scientists with new and new properties, there is little consistent with the traditional macroscopic world. Where exactly is the border between it and the quantum worlds, still remains an unsolved mystery. However, in a recent experiment, physicists finally managed to lift the veil of secrecy and show that even massive molecules can exist in two places at the same time.

How real is the teleportation?

The debate about whether one will instantly move the person to a more or less considerable distance, do not cease till now. A new discovery, showing that not only atoms, but also relatively large molecules are able to be in two places at the same time, a step brings humanity to his old dream of conquering great distances in a split second. A unique discovery was made through the use of a few of the upgraded dvuhmetrovoe experiment, often used in physics when studying the properties of photons of light. Thanks to him, scientists were able to come to the concept of duality of light behaving as a particle and wave simultaneously.

To conduct a double slit experiment is quite simple in practice. First of all you need to make sure the light source was directed to the surface of which has cut in it two slots. Behind a given surface it is necessary to place another surface on which will be projected on the light. If light consisted only of ordinary particles, the pattern on the back surface would appear only in the shape and size of the slots. However, the double slit experiment is so unique that the waves of light start suddenly Bouncing from each other like ripples in water, creating a sort of tiger pattern on the surface.

Holding dvuhmetrovoe experiment

But the strangest thing about the experiment is that even when the experience is conducted with individual particles of light appears the same striped pattern. Somehow these photons don’t seem to go only one way, as you would expect, and intersect and mix with each other.

In physics this phenomenon is called quantum superposition, which is best illustrated by Schrodinger’s cat. In this thought experiment a cat hidden in a box is neither alive nor dead, but exists in two States simultaneously. Upon opening the box the observer, the superposition collapses into one state or the other. Even more unusual experience is the fact that if the detectors were installed in the cracks in the measure passed by the light path, striped patterns would be immediately gone. The blurriness of the result becomes clear only once it is measured.

However, the phenomenon of superposition, apparently, only applies in the quantum domain, because as the objects become larger, the duality of light almost completely disappears in the macroscopic world. If so, is there a limit to the size of the object, which without any problems can be in two places at the same time? In order to answer this question, scientists from the universities of Vienna and Basel have done a double slit experiment with the largest molecules that have been tested in the history of physics.
