  Quantum technology is seeing a remarkable explosion in interest due to a wave
of successful commercial technology. As a wider array of engineers and
scientists are needed, it is time we rethink quantum educational paradigms.
Current approaches often start from classical physics, linear algebra, or
differential equations. This chapter advocates for beginning with probability
theory. In the approach outlined in this chapter, there is less in the way of
explicit axioms of quantum mechanics. Instead the historically problematic
measurement axiom is inherited from probability theory where many philosophical
debates remain. Although not a typical route in introductory material, this
route is nonetheless a standard vantage on quantum mechanics. This chapter
outlines an elementary route to arrive at the Schr\"odinger equation by
considering allowable transformations of quantum probability functions (density
matrices). The central tenet of this chapter is that probability theory
provides the best conceptual and mathematical foundations for introducing the
quantum sciences.
