Abstract
Special Collection: Celebrating the International Year of Quantum Science and Technology
One hundred years ago Werner Heisenberg proposed a new form of mechanics based on Bohr's 1913 theory of atoms, which very quickly led to the vibrant field of physics we know as quantum mechanics. A handful of novel and relatively simple concepts completely changed our understanding of nature. A few decades later, applications of quantum mechanics, such as semiconductors and lasers, revolutionized our world. Even today we are witnessing innovations based on these novel ideas, including applications of entanglement, which Erwin Schrödinger considered to be at the very core of quantum mechanics. Quantum mechanics still holds plenty to explore and still raises fundamental conceptual questions.
