The years 1920-1930 are regarded as an important decade in modern physics, in which every year epoch-making discoveries in quantum physics occurred. This prompted UNESCO to proclaim 2025 as the Year of Quantum Science and Technologies (IYQ).

The SPS started its IYQ2025 activities in 2024 with the historical symposium about Louis de Broglie - 100 years of wave-particle dualism, hold as vernissage at its annual meeting in Zürich, and continues the tradition at the joint annual meeting with the colleagues of the Austrian Physical Society (ÖPG) in Vienna in August 2025. One of the foci will be the scientific work of Wolfgang Pauli and Erwin Schrödinger in the years around 1925. Both physicists were born in Austria, but spent parts of their careers as professors of Physics in Zurich.
