Scientists create a developed quantitative node linking light and material

Quantum networks are often described as the future of the Internet – but instead of transferring classic information in bits, they send quantum information carried by photons. These networks can allow very external communication, link far away quantum computers together in one machine largely stronger, and create accurate sensors that can measure time or environmental conditions with unprecedented accuracy.

To make such a network possible, the so -called quantum network contract – which can store quantum information and share it through light molecules – is needed. In their latest work, the Innsbruck team, led by Ben Linyon, showed in the Department of Experimental Physics at Innsbruck University of such a node using a series of ten calcium ions on a model quantum computer. By carefully controlling the electric fields, the ions were transferred one by one to a visual cavity. There, the exactly seized laser pulse caused the emission of one photon that its polarization was intertwined with the state of ions.

The process created the photons flow. Eyon Eyon is associated with the record. In the future, photons can travel to remote nodes and use them to create tangles between separate quantum devices. The researchers have achieved a rate of average interconnection of the photon ion by 92 percent, a level of accuracy that emphasizes the durability of their method.

“One of the main strengths of this technology is the ability to expand,” says Ben Lanion. “While previous experiences managed to connect only two or three individual photons, the Innsbruck preparation can be extended to much larger records, which may contain hundreds of ions and more.” This paves the way to connect the entire quantity processors through laboratories or even continents.

“Our way is a step towards building more and more complex quantitative networks,” says Marco Cantiri, the first author of the study. “It brings us closer to practical applications such as quantum communications, distributed quantum computing and widely distributed quantitative sensors.”

Besides communication, technology can also provide visual atomic watches, which keeps time specifically to the point that it will lose less than a second over the era of the universe. These watches can be connected via quantum networks to form a system to save time around the world with unparalleled accuracy.

The work, which is now published in Physical review messagesIt was financially supported by the Austrian Science Fund FWF and the European Union, among others, and it is not only explained by an artistic milestone but also a basic brick for the next generation of quantum technologies.
