QuTech researchers present roadmap for quantum internet



20th October 2018 | 21:54 QuTech Researchers Present Roadmap to Quantum Internet may be the first quantum technology to become reality: the quantum Internet. Researchers from QuTech in Delft have published a detailed roadmap for the development of quantum internet in Science. They describe six phases, starting with simple networks of qubits that already allow some form of inherent secure quantum communication. In the last phase, there are networks of quantum computers associated with quantum technology. It may be the first quantum technology to become reality: the quantum internet.

Communication Technology

A quantum Internet would be a revolution in communication technology because it would use strange quantum phenomena such as entanglement. Researchers worldwide are working on the technology that would allow them to exchange quantum bits between any two points on Earth. Such quantum bits can have the values ​​"1

" and "0" as in classical bits, but also both at the same time. And they can be "entangled": their states are then connected so that the measurement works from one to the other.

Coordination

Therefore, the quantum Internet has unique features that will always be outside the reach of the classical Internet. The first, because by entanglement, activities in two widely separated places can be coordinated very precisely. As a result, clocks can be synchronized very precisely and observations from telescopes can be linked virtually, giving astronomers much sharper images. The second property is that quantum compounds are inherently safe. If two qubits are completely entangled, it is basically impossible to eavesdrop on the connection. This makes the entanglement particularly suitable for applications requiring security and privacy.

Preparation and Measurement

In the first phase of an actual quantum network – a "Prepare and Measure Network" – it is possible to send quantum bits between arbitrary points in a network. This is already sufficient to support various cryptographic applications. The Most Advanced Phase is the Quantum Connection of Fully Functional Quantum Computers
It is expected that the first quantum networks for the transmission of end-to-end qubits in the next few years will be realized on the way to large scale quantum networks [19659002] Original article can be found here
