About International Year of Quantum Science and Technology
The United Nations has declared 2025 the “International Year of Quantum Science and Technology”. Since quantum mechanics was first mentioned 100 years ago, it has been a fundamental pillar of our physical understanding of nature. This initiative aims to recognize the groundbreaking contributions of quantum science to technological development since 1925 and to raise global awareness of its importance for a sustainable future.
