Quantum Foundations Collection

One hundred years ago, Wolfgang Pauli, Werner Heisenberg, Erwin Schrödinger, and others laid down cornerstones of quantum mechanics. UNESCO has designated 2025 the International Year of Quantum Science and Technology in recognition of those breakthroughs and of the revolutionary impact that quantum science and technology have had and promise to have. To celebrate this centennial, the Editors of the Physical Review journals have collected the papers below that established the foundations for the field.

The collection opens with an Editorial by Dagmar Bruß of Heinrich Heine University Düsseldorf, offering an introduction to this exciting history and to the blossoming applications that, as UNESCO puts it, “are driving some of the most exciting breakthroughs of the 21st century.”
