  The transactional interpretation of quantum mechanics, which uses retarded
and advanced solutions of the Schrodinger equation and its complex conjugate,
offers an original way to visualize and understand quantum processes. After a
brief review, we show how it can be applied to different quantum situations,
emphasizing the importance of specifying a complete configuration of absorbers.
We consider in more detail the phenomenon of entanglement swapping, and see how
the apparent retroactive enforcement of entanglement can be understood in the
transactional interpretation.
