== Modern role == While many of the early discussions of complementarity discussed hypothetical experiments, advances in technology have allowed advanced tests of this concept. Experiments like the quantum eraser verify the key ideas in complementarity; modern exploration of quantum entanglement builds directly on complementarity:
The most sensible position, according to quantum mechanics, is to assume that no such waves preexist before any measurement. In his Nobel lecture, physicist Julian Schwinger linked complementarity to quantum field theory:
Indeed, relativistic quantum mechanics—the union of the complementarity principle of Bohr with the relativity principle of Einstein—is quantum field theory. The Consistent histories interpretation of quantum mechanics takes a generalized form of complementarity as a key defining postulate.
