Quantum Information Science and Technology (QIST) covers such fields as quantum communications, quantum computing or simulation as well as quantum sensing. Photonics plays a major role in QIST hardware and systems, and basic concepts from optical communications and information processing underpin many experiments and applications of QIST.
The promises of quantum technologies are impressive, but huge are also the challenges to understand and realize practical and reliable devices and systems. Major collaborative efforts around the world like the Quantum Flagship in Europe and the U.S. National Quantum Initiative are pushing research and early applications of quantum technologies. More specifically on quantum communication, China is getting a lot of attention for the Micius satellite and Europe is launching a Quantum Communication Infrastructure (EuroQCI) initiative.
In the symposium, we will discuss different aspects of QIST under the light of their relevance for optical communications. For quantum key distribution (QKD), which is one of the most mature applications, the focus is on the integration into a communications environment, the operator perspective and deployment experiences. We also look into the technological progress and future developments for QKD.
The second part of the symposium addresses the challenges for realizing full-scale quantum networks and the advanced applications such a network can support, like connecting quantum computers or sensors. In addition we discuss the role integrated quantum optics can play for photonic quantum computing.
