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.
