A years ago, world first quantum satellite was launched. It was not a propagation of radio wave rather information was encoded with dedicated photons. Infrared light was the key link for communication. It is an endless effort for developing a chip that might allow a classical computer. People would use classical computing most of the time. At the same time can connect with the quantum network for doing a complex task.

According to an international team of researchers, quantum teleportation between silicon chips has been achieved for the first time. This could be the basis for a future quantum internet.In recent months, researchers in quantum physics have made a number of breakthroughs. Google, for example , was able to prove the so-called quantum superiority , IBM presented the first commercially usable quantum computer, and researchers from Austria claim to have teleported a Qutrit . An international team of researchers is now said to have succeeded in quantum teleportation for the first time, as the standard reports .

Such an exchange between entangled photons on two separate silicon chips is considered an opportunity to transmit information indirectly. This in turn would correspond to a type of repeater that is currently used on the Internet to refresh data so that it can be transmitted over long distances between different nodes without loss. A quantum repeater could thus serve as a possible basis for a future quantum internet. In the journal Nature Physics, the researchers from China, Great Britain, Denmark, Australia and Austria presented their approach .

In their experiment, the scientists fed entangled light particles loaded with quantum information into spatially separated silicon chips. They then succeeded in indirectly transmitting the information by measuring the photon on the first chip on the entangled photon to derive the original state of the first. According to the researchers, this quantum teleportation between two silicon chips is a premiere, but is no more than a proof-of-concept, as the standard quotes Austrian researcher Marcus Huber. However, the successful teleportation between silicon chips is above all so promising for a possible future quantum Internet of the future because it can in principle be implemented with silicon chips and fiber optic cables. Both components are established in the IT infrastructure and therefore make rapid implementation more likely. According to Huber , the hardware used by the researchers is compatible with common chip production methods, and the built system is compatible with modern telecommunications infrastructure.
