| Abstract |
Centennial Lectureship in Physics In 1963, Professor E. C. G. Sudarshan presented the Optical Equivalence Theorem and thereby provided a quantitative, model-independent boundary between the classical and manifestly quantum domains of light. More than a decade then passed before nonclassical light first flickered dimly in the laboratory. By now, a zoology of nonclassical sources shine in laboratories around the world, with applications ranging from quantum measurement to quantum computation and communication. The Optical Equivalence Theorem of Professor Sudarshan has been the critical, guiding light in these quests, of which I will give an overview.
