Chicago brings Quantum Internet one bit closer

If you have not heard about the Quantum Internet, it might sound like science fiction, but the Quantum Internet is getting a little closer to a working reality. Scientists from around the world have steadily been increasing the distance at which typically photons can be entangled. Recently there was a similar announcement from Chinese Scientists.

Researchers from Argonne National Laboratory and the University of Chicago have now entangled photons across a 52-mile network in the Chicago.

“This is an important step forward in harnessing entanglement and building a network to help form the basis of future quantum communication systems”

The US government is firmly behind creating Quantum networks and has the strategic vision of companies working alongside national laboratories in terms of developing technology to enable a quantum network and quantum internet.

In achieving this Quantum milestone, Prof Awschalom and team worked closely with companies in the emerging quantum communication industry. In partnership with Qubitekk, a new company developing quantum technologies, the team created entangled photon pairs and distributed them across two 26-mile fibre circuits. The photon pairs that returned were detected, and their correlation was verified with a high signal-to-noise ratio.
