Recent advances in quantum technologies are enabling new functionality in communication networks. Quantum key management system support is available as a feature on commercial optical transmission systems and quantum random number generators are attracting attention for use in a variety of applications. At the same time, research is accelerating on the development of networked quantum computing to both scale existing platforms and to provide internet-like capabilities, perhaps to form a quantum internet. In addition to QKD-related applications, a new body of activity is developing around entanglement distribution and routing.  A race is on to develop a scalable and commercially viable quantum repeater for distributing entanglement and performing teleportation over long distances. Quantum sensor networks promise nonclassical sensitivity enhancements.  All these developments open up a wide range of potential new research areas in optical devices, communications and networks, spanning both the near and long term.

Key questions that this symposium will address include:

  • What are other applications of quantum networking beyond QKD?
  • Is optical quantum networking considered broadly just another version of classical optical networking, i.e., same methods, just different constraints? What are the new research areas created by bringing quantum technologies into optical networking?
  • What is the “quantum internet”? Are there bottlenecks to achieving quantum internet that are related to networking performance?
  • How far are prepare-and-measure/trusted QKD networks from the quantum internet/quantum network needed for (distributed) quantum computing?
  • What are the main quantum computing platforms and what role does photonics play?
  • What scale can we expect the quantum networks to reach in the short/medium/long term?
  • Are optical networks the best match for connecting distributed quantum computers?
  • What changes are necessary for the optical infrastructure to support a quantum internet in terms of hardware and software?

This symposium will explore these questions and others in regard to emerging research areas with a focus on optical communication technologies. The first session will provide high level overviews of broad areas with introductory or survey level talks followed by a panel discussion. The second session will breakdown specific areas in shorter talks, concluded with a panel discussion.

Session I (2h): Emerging research areas in quantum for optical communications

This session will provide broad overviews of key emerging research areas, including topics such as quantum enhanced security technologies in optical transmission systems, wavelength conversion and quantum computer/memory interfaces, quantum repeater network architectures for multi-partite entanglement distribution and teleportation, and quantum sensor networks and distributed quantum applications. The panel will discuss the current state of the art and the key research challenges.

Session II (2h): Examples of photonic research within emerging areas

This session will go into greater depth on specific research problems within the broad areas discussed in Session I. Talks will include areas such as measurement device independent quantum key distribution and novel security architectures, specific quantum memory technologies and architectures for quantum repeaters, quantum network routing algorithms, long baseline interferometry or similar quantum enhanced sensor networks, and error correction coding for quantum optical communications.  The panel will discuss recent research advances in these areas and existing challenges.
