  Starting with unitary quantum dynamics, we investigate how to add quantum
measurements. Quantum measurements have four essential components: the
furcation, the witness production, an alignment projection, and the actual
choice decision. The first two components still lie in the domain of unitary
quantum dynamics. The decoherence concept explains the third contribution. It
can be based on the requirement that witnesses reaching the end of time on the
wave function side and the conjugate one have to be identical. In this way, it
also stays within the quantum dynamics domain. The surjection hypothesis
explains the actual choice decision. It is based on a two boundary
interpretation applied to the complete quantum universe. It offers a simple way
to reduce these seemingly random projections to purely deterministic unitary
quantum dynamics, eliminating the measurement problem.
