We are closer to a quantum internet

It is potentially dead and alive

Boffins have emerged from their labs smeared with the bodies of dead cats, to announce that they have successfully teleported qubits of photons across approximately 27 miles of fibre-optic cable.

The move is important because it moves humanity one stage close to building a quantum internet which is a good thing as it is only potentially on and off.

While other scientists have worked on similar projects, this group is the first to beam quantum information across such a great distance. They did it over two separate networks and with a fidelity greater than 90 percent and used "off-the-shelf" components using tech is compatible with existing telecommunications equipment.

In PRX Quantum, which should be delivered and has already been delivered, they say their work provides "a realistic foundation for a high-fidelity quantum Internet with practical devices".

They wrote: "This is a key achievement on the way to building a technology that will redefine how we conduct global communication."

Experts believe a quantum internet could revolutionise a variety of computing fields, including cryptography and search. With two 13-mile networks under their belts, the Caltech and Fermilab teams plan to build a city-scale network called the Illinois Express Quantum Network in Chicago next.
