The first vapor film in the world

Quantum physicists at the Australian National University have successfully developed a completely new data storage method: vapor storage instead of solid-state storage such as DVDs or Blu-ray discs. This is the first time in the world that the images are 'stored' and played in a somewhat reliable environment.

In the experiment, scientists used lazer and magnetic fields to store the letters 'N' and 'T' in a 20 cm long bin, called GEM, filled with vapor. the Rubidium. Then press a button that reverses the magnetic field to slightly play the image of the two letters above. The result is 2 letters appearing in very short time, 1 / millionths of a second.

"We want to change the way movies are stored and based on quantum technology," said Quentin Glorieux, one of the researchers. 'The storage of information in quantum form can be a precursor to the birth of quantum internet.'

However, to make this storage method more realistic, scientists need to overcome the nuisance of molecular vapor that damages the image.
