Limitations on the use of the Heisenberg picture

Published 2018-11-15Version 1

The Schrodinger and Heisenberg pictures are equivalent formulations of quantum mechanics in the sense that they give the same expectation value for any operator. We consider a sequence of two or more unitary transformations and show that the Heisenberg operator produced after the first transformation cannot be viewed as the input to the second transformation. The experimental consequences of this are illustrated by several examples in quantum optics.
