A photon teleports almost 100 kilometers away

Who has never dreamed of being able to teleport, for example when you have to make a trip of several hours or return home after a long day at work? Although the possibility of instantaneous 'travel' is still a utopia, scientists are making giant strides in the field of quantum teleportation, a system that promises to revolutionize the world of telecommunications.

Quantum teleportation does not consist of transporting objects, but of bringing two particles together in such a way that the change of state of one of them is instantly reflected in the other , regardless of the distance that separates them and without the need for physical support of any kind. . Scientists have been working on and perfecting this system for quantum bonding between particles for years, and now a team from the Shanghai University of Science and Technology has set a new record by teleporting photons 60 miles through the air.

The researchers have shown their results in an article published in the journal arXiv in which they explain that "compared to other works, our experiment has increased the distance by two orders of magnitude. Our results demonstrate the feasibility of using quantum teleportation, for example, in communications between satellites and ground-based stations ".

Why have Aspect, Clauser and Zeilinger won the Nobel Prize in Physics?

This year's Nobel Prize in Physics has gone to three physicists who decided to respond to Einstein's last great challenge, and thanks to them an entire discipline was opened: quantum information.

They create a state of matter that occupies two dimensions

It could be a breakthrough for supercomputers that carry out complex tasks. A new path to quantum computers?

Aliens could send quantum messages to Earth

Hidden messages in the stars? A study concludes that quantum signals could make their way across interstellar distances.

Will a theory of everything ever be discovered?

We are at the beginning of the search for a theory of everything that explains, without recourse to more fundamental principles, the workings of the universe.
