QED-C roadmap flags key infrastructure needs for quantum networks

The Quantum Economic Development Consortium has released a new roadmap outlining the technologies needed to scale quantum networking for secure communications, networked computing and sensing. The report says switches, repeaters and satellite infrastructure could unlock most high-impact applications, while today’s systems still support only a narrow set of short-distance uses.

Why it matters: - Quantum networks could expand the value of quantum computing, sensing and security by letting quantum information move reliably across systems, longer distances and multiple users. - The roadmap identifies where investment and research could have the biggest payoff for commercially relevant quantum applications. - The report says today’s networks are still too limited for most of the applications assessed.

What happened: - The Quantum Economic Development Consortium released a new Quantum Networking Applications Roadmap on July 29, 2026. - The roadmap maps 10 quantum networking applications across secure communications, networked quantum computing and networked quantum sensors. - The applications include quantum key distribution, blind quantum computing, clustered and distributed quantum computing, and distributed quantum sensing. - QED-C and the Center for Quantum Networks developed the roadmap jointly. - The effort builds on an earlier roadmap from the Center for Quantum Networks.

The details: - The roadmap says quantum optical network switches, quantum repeaters and quantum satellite infrastructure are needed for most of the applications studied. - Quantum light sources and light-matter interfaces are also critical for many of the applications. - The report says current quantum network performance can support only two assessed applications: quantum key distribution and distributed quantum sensing. - Those two applications are supported only in point-to-point, short-distance deployments. - The roadmap says improvements are needed in qubit transmission rate, transmission distance, fidelity and synchronization. - The report says 9 of the 10 high-impact applications could be enabled by advances in each of the following: quantum optical network switches, quantum repeaters and quantum satellite infrastructure. - Contributors came from industry, government, academia and national laboratories. - Named participants included L3Harris Technologies, IonQ, the University of Arizona, SRI International, the National Science Foundation, the National Institute of Standards and Technology, Argonne National Laboratory, Fermi National Laboratory, Horizon Quantum and Aliro Quantum.

Between the lines: - The roadmap narrows the field of quantum networking into specific infrastructure bottlenecks instead of treating the sector as a single technology stack. - That framing could help funders, policymakers and companies prioritize parts of the network most likely to unlock usable systems. - The findings also show a gap between near-term demonstrations and broader commercial deployment. - “QNAR 2.0 represents a major step forward in our understanding of commercially relevant quantum networking applications and their technical requirements,” said Saikat Guha, co-director of the Center for Quantum Networks. - Guha said the roadmap is meant to align research with high-impact use cases and help accelerate technology transition.

What's next: - QED-C will discuss application requirements, market opportunities, benchmarking frameworks and R&D priorities during a webinar titled “Advancing Quantum Networking Applications” at 11 a.m. EDT Aug. 12. - The full roadmap is available as the Quantum Networking Applications Roadmap. - Registration for the webinar is available through the QED-C event page.

The bottom line: - QED-C’s roadmap argues that quantum networking will not scale on applications alone; the field needs targeted infrastructure upgrades in switches, repeaters, satellites and related components first.
