It Wasn't Adultery …

… it was a superposition of states:

At Oxford, where he fled the Nazis, Schrödinger lived openly in a threesome with his wife and a mistress (the wife of his assistant), who bore him a daughter in 1934. In Dublin, where Schrödinger and his two “wives” eventually landed in 1940 as he became the director of the School for Theoretical Physics, the quantum genius had more love affairs and fathered more children.

In each eigenstate, he was married to somebody else.
