Quantum Networks: Challenges and Opportunities
Metcalf’s law quantifies the value of a telecommunications network is proportional to the square of the number of users. It is anticipated that the value of a quantum network will scale exponentially with the number of connected quantum devices. At present, quantum devices are very diverse in terms of how quantum information is encoded. It seems likely that these diverse devices will need to be optically networked using optical fiber. Yet exactly how to do that depends upon the nature of the underlying quantum information applications. The most common approach focuses on distributing two-qubit entanglement, but it is not clear that will be sufficient, for example, in instances where networked quantum sensors use squeezing. The purpose of this workshop is to get the quantum optics, optical fiber networking, and future applications developers to discuss what is needed.
Several national quantum initiatives have launched or are in the early stages of starting one. All seek to develop quantum processing technologies. It seems likely that these technologies will need to be connected by quantum networks, and most national quantum initiatives have called out quantum networks specifically. However, there is a disconnect between the quantum physics community (home of quantum mechanics), quantum engineering (optical engineering, quantum networks engineers, and quantum computing) and classical high performance computing HPC (computer science, applied math, and domain science) that have to be engaged in a co-design-like approach to develop this technology in a way that can be scalably deployed and utilized.
