International Year of Quantum Science and Technology draws to a close

The International Year of Quantum Science and Technology (IYQ) has officially come to a close, marking a year of global celebration and exploration of quantum physics. The culmination of this international initiative took place in Accra, Ghana, with a two-day event that brought together government officials, UNESCO representatives, physicists, and members of international scientific societies.

Launched in February 2025 at UNESCO's headquarters in Paris, IYQ was designed to highlight the science and applications of quantum physics, which has transformed various fields such as communications, computing, medicine, and even the arts. The year was chosen to coincide with the centenary of the initial development of quantum mechanics by Werner Heisenberg, a pivotal moment in the history of physics.

Throughout the year, hundreds of organizations worldwide participated in events celebrating quantum science and technology. The Institute of Physics (IOP), which publishes Physics World, was among the key partners in organizing these activities. The IYQ events showcased the diverse ways in which quantum physics is being applied and advanced, from groundbreaking research to practical innovations.

One of the most significant events during IYQ was a workshop held on the German island of Helgoland in June 2025. The island holds historical significance as it was the location where Heisenberg made his groundbreaking breakthrough exactly 100 years earlier. The workshop attracted more than 300 top quantum physicists, including four Nobel laureates, who engaged in discussions, poster sessions, and debates to explore the future of quantum science.

Another notable event was the IOP's two-day conference, "Quantum Science and Technology: The First 100 Years; Our Quantum Future," which took place at the Royal Institution in London in November 2025. This conference brought together experts to reflect on the past century of quantum advancements and envision future developments.

The closing ceremony in Ghana, held on February 10-11, 2026, served as a fitting conclusion to the IYQ. Attendees, including government officials, UNESCO directors, physicists, and representatives from international scientific societies, discussed the official 2025 IYQ report and enjoyed a reading of the winning entry from the IYQ 2025 poetry contest. The event also featured an exhibition with displays from IYQ sponsors, offering a glimpse into the innovative technologies and research being driven by the quantum science community.

Organizers of the IYQ expressed hope that the impact of the year would be felt for many years to come. Duke University physicist Emily Edwards remarked, "The entire 2025 year was filled with impactful events happening all over the world. It has been a wonderful experience working alongside such dedicated and distinguished colleagues."

In conclusion, the International Year of Quantum Science and Technology has successfully showcased the profound influence of quantum physics on various aspects of modern life. As the event in Ghana marked the official end of IYQ, the global community looks forward to continued advancements and collaborations in this exciting and rapidly evolving field.
