The meeting started with several Working Group (WG) and Ad-hoc Group (AhG) meetings on the first day in Nordhavn, in the beautiful city of Copenhagen, Denmark.
The second day was dedicated to the European Quantum Technology Conference (EQTC 2025), also held in Copenhagen, the goal of which was to foster collaboration among researchers, industry, and policymakers, emphasizing standards as a key tool for quantum technology.
The third and fourth days were reserved for the JTC 3 Plenary Meeting, which included a visit to DTU Nanolab on the afternoon of the 13th. There were 155 participants (out of which 59 were remote), from 24 countries. The meeting began with the approval of the agenda, followed by reviewing and updating the work programme and the project plans, and proposing the future work programme. I will only report on what is interesting for the Swedish part.
AG 1 Strategic planning reported the 3–5 year strategic objectives, including coordinating global expertise on quantum technology standardization, working with industry and other stakeholders to identify priority standards, establishing an initial work program and substructure for its effective delivery, and raising industry awareness of the benefits of contributing to quantum technology standards.
WG 9 Terminology and quantities changed the role of Project Leader for IEC/ISO 63607 ED1. It approved a revision of ISO/IEC 4879:2024 ‘Information technology — Quantum computing — Vocabulary’.
WG 10 Quantum sensors: The Korean National Committee proposed two Preliminary Work Items (PWI) which were approved.
AhG 5 Quantum Computing and Simulation reached its end and was approved to be disbanded after the IEC/ISO JTC 3 plenary meeting in Denmark, following the creation of WG 11 “Quantum computing supply chain” and WG 12 “Quantum computing benchmarking”. The French National Committee proposed a Subcommittee (SC), which is still under discussion.
AhG 4 Quantum Communication will be disbanded following the completion of its task. A new WG Quantum Communication will be formed with a registered Technical Report (TR) about the influence of transmission media on the implementation of quantum communication.
AhG 7 Quantum enabling technologies reached its end and provided an internal report. A new WG will be formed and proposed two TRs on mapping and classification of cross-cutting and enabling devices and technologies, and single photon sources/devices.
WG 11 Quantum computing supply chain: A TR on Quantum Computing – Hardware Supply Chain is registered.
WG 12 Quantum computing benchmarking: A TR on Survey and classification of algorithmic and application benchmarking techniques is registered.
WG 13 Quantum random number generators: Is working on a TR on ‘Quantum technologies – Overview of quantum random number generator’. There is an ongoing discussion about which committee should take responsibility.
Some liaisons to other IEC/TC groups were proposed and selected.
The next plenary meeting will be held in Jinan, China, in May 2026.
