Adapting Existing Computer Networks to a Quantum-Based Internet Future

Tech ID: 32539 / UC Case 2021-607-0


Researchers at the University of California, Davis have developed an approach for integrating quantum computers into the existing internet backbone.

Full Description

Quantum computing offers the potential for faster and more secure communications, as well as applications ranging from personalized health to lower-cost financial transactions. Realizing its full potential, however, requires overcoming multiple challenges. Even more complex is the prospect of a quantum computing-based internet backbone. Some recent progress implies small-scale implementations of quantum networks can be achieved within the medium term. On a larger scale, viable network controls, management, and operation protocols for quantum networks are still in development. Furthermore, historical trends suggest that successful transitions in networking technologies will occur more seamlessly when upgrades to new technologies focus on transitional interoperability.

Researchers at the University of California Davis have developed a networking procedure to enable the transfer of quantum data, alongside “classical” data, on existing infrastructure. This method involves “wrapping” classical data around a payload of quantum data – an approach known as Quantum Wrapper Networking (QWN). The technology enables current data receiving systems to process quantum data using today’s networking platforms. QWN technology offers the architecture, protocols, algorithms, and methods that can control and manage quantum networks with full interoperability and backward compatibility with existing classical computing networks.
