The quantum information superhighway promises fully faucet-proof verbal exchange and robust disbursed sensor networks for brand spanking new science and know-how. however, because quantum suggestions cannot be copied, it is not possible to ship this suggestions over a classical network. Quantum suggestions ought to be transmitted via quantum particles, and particular interfaces are required for this. The Innsbruck-primarily based experimental physicist Ben Lanyon, who was awarded the Austrian beginning Prize in 2015 for his research, is investigating these essential intersections of a future quantum cyber web.

Now his group on the department of Experimental Physics at the school of Innsbruck and on the Institute of Quantum Optics and Quantum assistance of the Austrian Academy of Sciences has finished a list for the switch of quantum entanglement between matter and light. For the primary time, a distance of fifty kilometers turned into coated using fiber optic cables. "this is two orders of magnitude additional than was prior to now feasible and is a realistic distance to delivery building inter-city quantum networks," says Ben Lanyon.

transformed photon for transmission

Lanyon's group all started the test with a calcium atom trapped in an ion trap. the use of laser beams, the researchers write a quantum state onto the ion and concurrently excite it to emit a photon during which quantum suggestions is stored. because of this, the quantum states of the atom and the mild particle are entangled. but the problem is to transmit the photon over fiber optic cables. "The photon emitted by means of the calcium ion has a wavelength of 854 nanometers and is right now absorbed by using the optical fiber," says Ben Lanyon. His group for this reason at the beginning sends the light particle through a nonlinear crystal illuminated by using a strong laser. Thereby the photon wavelength is transformed to the most beneficial price for lengthy-distance commute: the present telecommunications normal wavelength of 1550 nanometers. The researchers from Innsbruck then ship this photon via a 50-kilometer-lengthy optical fiber line. Their measurements exhibit that atom and lightweight particle are nevertheless entangled even after the wavelength conversion and this long journey.

Even better distances in sight

As a next step, Lanyon and his crew display that their methods would permit entanglement to be generated between ions one hundred kilometers apart and more. Two nodes ship each an entangled photon over a distance of fifty kilometers to an intersection where the mild particles are measured in such a way that they lose their entanglement with the ions, which in turn would entangle them. With a hundred-kilometer node spacing now a opportunity, one may hence envisage building the area's first intercity light-rely quantum network in the coming years: best a handful of trapped ion-methods can be required on a way to establish a quantum information superhighway between Innsbruck and Vienna, as an example.

Lanyon's team is part of the Quantum internet Alliance, a global project within the Quantum Flagship framework of the european Union. The existing results had been posted within the Nature journal Quantum tips.
