QuTech, a quantum research institute based in Delft, has published new work in which three nodes that can store and process quantum bits (also called qubits) were linked. This, according to the QuTech researchers, is the world's first rudimentary quantum network.
It would be the harbinger of an entirely new medium of calculation, harnessing the powers of subatomic particles to obliterate the barriers of time in solving incalculable problems.
Connecting quantum devices is by no means a novelty: many researchers around the world are currently working on similar networks, but so far have only succeeded in linking two quantum processors. Establishing a multi-node connection, therefore, is a key step towards significantly expanding the size of the network.
Driving much of the research effort is the objective of creating a quantum internet that could one day stretch across the surface of the planet. The quantum internet would exploit the strange laws of quantum mechanics to let quantum devices communicate with each other, and is expected to unlock a range of applications that cannot be run with existing classical means.
For example, the quantum internet could link together small quantum devices to create a large quantum cluster with more compute power than the most sophisticated classical supercomputers.
"A quantum internet will open up a range of novel applications, from un-hackable communication and cloud computing with complete user privacy to high-precision time-keeping," said Matteo Pompili, a member of QuTech's research team. "And like with the internet 40 years ago, there are probably many applications we cannot foresee right now." READ MORE
