Ultra-secure quantum data sent over existing internet cables

Quantum Communication Milestone Could Pave Way for Faster, More Secure Internet

Learn how physicists were able to send quantum signals through fiber optic telecom system.

With quantum technology, the Internet is to be wired. To date, special cables and extreme cooling were required for test systems. An experiment in Germany shows that things are going differently.

It was a record quantum transmission, the one obtained in Germany along a normal fiber optic cable, such as those used for the Internet connection: the quantum message traveled 250 kilometers and demonstrated that the communications of the future, very fast and secure, could be closer than thought. The result, published in the journal Nature, was obtained thanks to the experiment led by the Italian Mirko Pittaluga who, after studying at the Univ…

The future of quantum technology does not mean that every home or every company or entity has a computer with extraordinary capabilities. Its viability goes through the network, through a network of connections that allow us to take advantage of the advantages of this new computing with computers of lower individual capacity, from any research or corporate center and that, ultimately, is useful for users. But to create this network it is necessa…

Ultra-secure quantum data sent over existing internet cables

Two commercial telecommunications facilities have been connected by a secure quantum network that used existing fibre optic cables at room temperature – a key step towards a feasible quantum internet

It was a record quantum transmission, the one obtained in Germany along a normal fiber optic cable, such as those used for the Internet connection: the quantum message traveled 250 kilometers and demonstrated that the communications of the future, very fast and secure, could be closer than thought.
