Abstract: Modular systems were first proposed as a route to scalable quantum computation two decades ago. Key ideas were studied in the 2005-2015 time frame, then a lull ensued as researchers focused on near-term, single-device systems. In the last two years, a burst of activity in the field has resumed, mostly centered on mechanisms for making high-fidelity inter-node entanglement. I will review that recent progress and address the open issues in extending from single links to networks, including presenting our own progress.

Abstract: Research activities on quantum technology have been carried out on multiple fronts in Thailand, including in quantum computing (primarily on theoretical work and quantum algorithms), quantum sensing (atomic clock, magnetic sensors with nitrogen-vacancy centers in diamonds) and quantum communication (single photon source, photonic circuits, quantum memory, quantum network optimization). Concerning quantum communication, efforts toward the standardization and regulation of quantum-safe cryptography are advancing to address emerging security challenges posed by quantum computing. This includes both post-quantum cryptography (PQC) and quantum key distribution (QKD). National initiatives aim to align with global standards, focusing on developing frameworks for secure communication, certification, and implementation. These activities are crucial to ensuring that Thailand remains prepared for the post-quantum era, safeguarding sensitive information against future quantum threats while fostering international cooperation in the field. Moreover, these activities are conducted concurrently with the main-stream research in fundamental science and engineering to obtain or improve elements in quantum communication such as single photon source, quantum memory, quantum photonic chips, waveguides and quantum network optimization.
Speaker: Oskar van Deventer
Abstract: The QIRG contribution on “Modelling chains of Quantum-Repeaters Chains” was shared via the QIRG email list on Wed 12 Mar. It models nodes in chains of quantum repeaters at two abstraction levels.
The contribution introduces terminology that will enable quantum hardware/software vendors, system integrators, and quantum-network operators to univocally classify equipment for design, planning and configuration.
The purpose of this contribution is to evoke feedback from the QIRG community.
Bio: Dr. Oskar van Deventer is a senior researcher at the Dutch research institute TNO. He is working on an explorative project for a TNO decision whether/where to invest in quantum-repeater technologies. He is also chair of CEN-CENELEC JTC22 on Quantum Technologies.

Abstract: There is much work in the R&D domain on entanglement-based networks and applications but much of it is focused on working towards the quantum memory network stage and beyond despite there being two stages, the prepare-and-measure and entanglement generation network stages, between them and today's QKD networks, i.e., trusted repeater network stage. This jump is understandable given that the most promising applications with the most significant quantum advantage lie in the later stages but the reality is that there are still many years of research and experimental development still needed to reach the quantum memory network stage. It would be unproductive if we do not devote at least some effort to exploring the intermediate two stages given that many applications in these stages are feasible with hardware that is commercially available.
To address this gap, an inventory of quantum network applications would be useful. In this presentation I will identify the potential functionalities in which quantum networks can provide practical benefits over classical methods today (or at least in the very near term). I also hope that this inventory will provide a bridge that will help connect the work put into the deployment of QKD networks with next-generation quantum network development by slowly eliminating the dichotomy between the two types of network. After all, they are both quantum networks that need to transmit single photons on a fiber with many similarities at the network control and management level.
