In a deep-dive session at Cisco Live, Ramana Kompella, head of Cisco Research and Cisco Fellow, detailed precisely what quantum networking is, how it works at a theoretical level, and what Cisco is building to enable real world applications.
During his session, Kompella made the case that the bottleneck to practical quantum computing is not the processor. It is the network connecting processors together. His argument drew directly from the history of classical infrastructure: The same scale-out methodology that built the modern internet could, he said, accelerate the arrival of useful quantum computing by decades.
“Quantum networking can accelerate the arrival of practical quantum computing by decades by using the scale-out methodology that we’ve used successfully in our classical infrastructure,” Kompella said.
How quantum networking actually works
The starting point is understanding why quantum networks cannot be built like classical ones.
