QUANT-NET brings together world-leading expertise in quantum technologies, optics, materials, networks, testbed operations, and other assets from Berkeley Lab, UC Berkeley, and Caltech in order to build a proof-of-concept quantum network based on entanglement.

This software-controlled, application-focused quantum computing network will link Berkeley Lab and UC Berkeley. The three-node distributed testbed will feature an entanglement swapping substrate over optical fiber and will be managed by a quantum network protocol stack. The collaboration will also demonstrate entanglement between small-scale quantum computers at the two testbed locations.

The idea for QUANT-NET grew out of the 2020 DOE Quantum Internet Blueprint workshop, where representatives from DOE national laboratories, universities, industry, and other U.S. agencies came together to define a roadmap for building the first nationwide quantum Internet. Quantum networking is poised to revolutionize how information is transmitted between quantum systems, locally and over long distances, and is expected to have a major impact on large-scale sensing experiments, making it of key interest to basic researchers working in areas such as astronomy, materials discovery, and life sciences.

The project is funded by the Advanced Scientific Computing Research (ASCR) division of Office of Science, U.S. Department of Energy
