Quantum-Augmented Network (QuANET) is sponsored by DARPA. A program integrating quantum links into classical communications infrastructure to create a resilient and secure networking environment.

Department of War organization. Quantum-Augmented Network Can you blend the best of both classical and quantum communications to produce a scalable, vastly more secure networking infrastructure? That is the question DARPA seeks to answer through its Quantum-Augmented Network (QuANET) program.

It’s well known that even the most advanced classical networks, such as the internet, are susceptible to the constant barrage of ever-evolving cyberattacks. Quantum networks could mitigate these vulnerabilities and protect data by using quantum properties. The challenge, however, is that today’s various quantum implementations lack cohesion, resulting in systems that can’t work together.

Through QuANET, DARPA will explore how integrating quantum and classical approaches to networking could provide quantum physics-based security capabilities to critical network infrastructures. QuANET researchers will focus on combining current and near-future quantum networking infrastructure (both hardware and protocols) with classical infrastructure with the goal of delivering security capabilities relevant to national security.

DARPA experts estimate that by doing so, they can achieve the efficient security and covertness properties of quantum networks with the pervasiveness of classical networks. QuANET seeks to enable network infrastructure to use quantum systems that incorporate quantum communications in various ways. Successful solutions will have the potential to scale up to the size of a metropolitan area network.
