Niels Bohr, greatest physicist of the 20th century
... The development during the present century is characterized by two theoretical systems essentially independent of each other: the theory of relativity and the quantum theory. The two systems do not directly contradict each other; but they seem little adapted to fusion into one unified theory. For th ...

Essential for these developments, however, is the ability to take a quantum system with a few discrete states, such as an exciton in a quantum dot or impurity state in a crystal, and control its wavefunctio ...
