This edition celebrates the UN International Year of Quantum Physics and Quantum Technology (IYQ 2025), marking a global commitment to advancing quantum science.

Building on the successes of PGU workshops in 2016 and 2018, PGU‑3 aims to foster an interdisciplinary exchange among physicists, astro-cosmologists, and technologists. The workshop will explore the frontiers where quantum mechanics, particle physics, and gravitation converge, examining both foundational theory and emerging quantum-enabled technologies. Like its predecessors, the workshop will review cutting-edge developments, present new theoretical and experimental results, and discuss their broader scientific and technological impacts.

Over the past century, physics, driven by the ideas of quantum theory, has undergone remarkable developments, offering new insights into our understanding of the Universe at both microscopic and macroscopic scales. PGU‑3 welcomes leading invited speakers, contributed talks, and poster presentations. The workshop also aims to strengthen education and research in Vietnam and the Asia–Pacific region, while fostering collaboration across international institutions. Participants are encouraged to register and submit abstracts for contributed talks or posters via the workshop website. We look forward to a stimulating three-day program of plenary sessions, focused discussions, and informal networking opportunities in the vibrant city of Hanoi.

Scope of the workshop

In celebration of the UN International Year of Quantum Physics and Quantum Technology (IYQ 2025), the workshop will review recent developments, current status, interdisciplinary connections, and technological impacts of particle physics, astrophysics, and cosmology, emphasizing their deep links with quantum theory and quantum-enabled technologies, from both theoretical and experimental perspectives. The workshop will cover (but is not limited to) the following topics:

• Quantum foundations of atomic-, nuclear-, and condensed matter physics.
• Quantum field theory and the Standard Model.
• Physics beyond the Standard Model.
• CP violation and flavour physics.
• Neutrino physics and flavor oscillations.
• Collider physics and advanced detector technologies.
