quantum network

From Inside HPC, July 23, 2020: The Department of Energy unveiled on July 23 a strategy for the development of a national quantum internet intended to bring “the United States to the forefront of the global quantum race and usher in a new era of communications.” Earlier this year, Argonne National Laboratory and the University of Chicago entangled photons across a 52-mile “quantum loop” in the Chicago suburbs, “successfully establishing one of the longest land-based quantum networks in the nation,” according to DOE. That network will be connected to Fermilab, establishing a three-node, 80-mile test bed.

From The Wall Street Journal, July 23, 2020: The network, which uses quantum principles to more securely transmit data, could be functional in about a decade. Argonne National Laboratory and the University of Chicago established in February a quantum network of 52 miles’ worth of entangled photons running on unused telecom fiber in the Chicago suburbs. In about a year, the network is expected to be connected to Fermilab, creating an 80-mile quantum internet test bed.

From EurekAlert!, March 6, 2020: Caltech and JPL have designed a practical, high-rate, high-fidelity quantum communication system over fiber and free space. The team is on track to deploy, commission and demonstrate both concepts, including a free-space, municipal quantum link between JPL and Caltech, in 2020-21. They will also establish a space-based quantum optical connection between the Caltech-JPL quantum network and quantum networks in the Midwest, including Fermilab’s FQNET and IEQNET, together with Argonne National Laboratory.

Researchers are wielding quantum physics, technologies and expertise to develop a proposed Illinois Express Quantum Network, which would stretch between Fermilab and Northwestern University’s Evanston and Chicago campuses. The metropolitan-scale, quantum-classical hybrid design combines quantum technologies with existing classical networks to create a multinode system for multiple users.
