Mona Lisa was portrayed as "quantum screen" as small as human hair

Mona Lisa, Leonardo da Vinci, was modeled in a miniature or similar "quantum screen", a width or similar human hair.

The physicists used lasers to create a replica of Da Vinci's famous masterpiece, which is not a very cold lump of gaseous quantum matter.

The art is pulled by projecting a famous image with a laser back over a microscope – to make it small – and then remove the result.

The lasers interact with the strange properties of quantum matter to change the density of the atoms and to create pixels that have been differently colored.

Researchers copied dozens of other images using this technique – including Starry Night Van Gogh and a picture of one of the quantum physicists.

The physicist Tyler Neely and his colleagues from the University of Queensland have made the small craft of rubella gas cooling to a few million pounds or similar grade above absolute zero, the lowest possible temperature.

"The gas doesn't freeze because it's too weak but it's behaving like a lump of gaseous quantum matter," Dr. Neely.

"Then we used a laser to protest the image or the similar projector, but don't really implement it, but send it back through a microscope to make the image small," he added.

"This light is stamped with the image or similar area with a width of about 100 micron."

This is as small as human hair whose diameter is between 17 and 181 micron, so that the work is not visible to the naked eye – there are only 50 atoms per one.

The strange quantum issue that forms the canvas of the researchers for these works of art is a kind of condensation Bose-Einstein – the fifth mysterious state of consolidation alongside solids, liquids, gases and plasma.

They form when an issue is approaching an absolute zero (-273 ° carbon / -459 ° fluorine), where atoms do not move and cluster with each other as if they were one unit.

These materials have strange quantum properties that are visible or similar – including the ability to flow smoothly as it's called "superfluid".

These unusual properties were inspected by Dr. Neely and colleagues when they discovered how to create a new art form.

"We never wanted to do that – we wanted to better understand the unresolved puzzles of liquid flow," Neely.

"We had hoped to get new insights, not … how our world every day comes to the fore from the microscopic quantum world, and helps us develop new technologies by improving them." quantum.

"But although we are there, we happened to create some of the world's smallest masterpieces."

Making the art is not as easy as throwing light on the material, as if you were throwing a film on a film screen.

Instead, the technique treats the strange quantum properties of the Bose-Einstein condensate – until the atoms are measured, they have no specific situation.

Instead, they behave as if they have been distributed throughout the system.

However, when researchers illuminate non-significant lasers, the light measures the system and shows that the atoms where the lasers are illuminated.

As a result, the atoms focus on the darker parts of the image and the artwork is being drawn up.

"The condition of Bose-Einstein's condensation is destroyed by lighting it with light and the quantum state with the act of measurement," Dr. Neely opposite New Atlas.

The shadow is in the images so represent the density of the atoms that he added.

Although the images produced are in black and white only, researchers can create color versions by creating three different images – one each for blue, green and red tones – and then combed with a computer.

These first images show the potential of a quantum issue as a new material for making artwork, says the researchers.

"The next step is to expand the creative expression of this medium," says Dr. Neely.

We now want to work with an artist to realize a creative vision for this technology. "
