Complete quantum teleportation implemented!

FINALLY full quantum teleportation done! For the first time, physicists transferred an atom from one place to another inside an electronic chip. Do you understand what such an event is fraught with? Let's call it a local breakout. The findings could lead, according to Arkady Fedorov of the University of Queensland, to larger electronic networks and more functional electronic chips.

“This is a process by which quantum information can be transferred from one place to another without the need to transfer a physical medium, ” says Fedorov. “Information appears only at the destination, like a teleportation in the popular sci-fi movie Star Trek.

However, this series inspired scientists to create many other interesting things.

Fedorov notes that the key resource of quantum teleportation is a certain type of correlation known as entanglement (we have written about this more than once), which unites the sender and the receiver.

“As soon as entanglement forms, this impossible transmission of information becomes realistically possible thanks to the laws of quantum mechanics, ” says Fedorov. "For the first time, the amazing quantum teleportation process can be used to transfer information in a circuit from one corner of the sample to another."

What makes Fedorov's work interesting is that his system uses the circuitry on which modern computer chips are built.

“In our system, quantum information is stored in artificial structures - quantum bits - and can be seen with the naked eye. This is somewhat surprising because people assume that quanta are weighed on an atomic scale and are not visible even with electron microscopes. "

Quantum teleportation allows information to be transmitted with impressive speed and accuracy, many times greater than modern methods.

“In our laboratory of superconducting quantum devices, we use this technology to strengthen our knowledge of the nature of quantum physics. Ultimately, much more powerful devices will be built on the basis of this technology. "

The study shows that questions of quantum physics and quantum communication can be solved in the conditions of electronic circuits at microwave frequencies.

“In the future, quantum information may be transmitted over long distances directly through microwaves to optical interfaces, ” says Fedorov. Well, another small step has been taken towards teleportation.
