NQIAC Report on Quantum Networking

(September 6, 2024) Today, the National Quantum Initiative Advisory Committee published its second independent assessment on the National Quantum Initiative (NQI) program, focusing on quantum networking and the role that testbeds play in research and development of quantum networking technologies. The report, titled Quantum Networking: Findings and Recommendations for Growing American Leadership identifies six findings and seven recommendations:

Findings:

  1. Quantum networking capabilities will play a role in U.S. economic prosperity and national security, but the magnitude of that role will only be clarified through sustained research and development (R&D).
  2. Continued investment in R&D by the U.S. Government will be necessary to determine, understand, and realize the advantages of quantum networking for practical applications.
  3. Quantum networking R&D can complement and enhance progress in advancing other quantum information science technologies.
  4. The term “testbed,” as it relates to quantum networks, is used ambiguously. Testbeds are distinct from demonstrators, prototypes, and user facilities as per the following definition, which the NQIAC will use in its recommendations:

A testbed is a platform or facility that is accessible to multiple users to conduct replicable and rigorous testing of component technologies, protocols, and systems integration.

  1. Early quantum networking prototypes, demonstrators, and testbeds are in operation, with practical or economic impact yet to be determined.
  2. Quantum networking testbeds, if strategically chosen and properly timed, can play an important role in accelerating U.S. quantum information science leadership.

Recommendations for the U.S. Government to grow American leadership in quantum networking:

  1. Continue to support fundamental research in quantum networking, its applications, and its enabling technologies.
  2. Encourage the definition, development, and use of metrics to measure progress on quantum networking technologies and their applications.
  3. Support the development of a coordination model for describing the functional layers of quantum networks.
  4. Federal funding for quantum networking testbeds should be allocated when testbeds are both “right-sized” and “properly-timed.”
  5. Support and facilitate industry participation in quantum networking testbeds.
  6. Prioritize new funding appropriations and the development of new mechanisms to promote collaboration with international allies and like-minded partners for quantum networking R&D.
  7. Leverage quantum networking testbeds to enable and train a diverse quantum workforce.

As legislated by the NQI Act, the NQIAC is tasked with submitting its reports to the President and appropriate committees of Congress.
