  Quantum mechanics is an integral course for physics students. An
understanding of quantum concepts is imperative for enrollment in physics
graduate programs, participating in research within physics-fields, and
employment at companies developing quantum technologies. This study analyzes
188 US research intensive institutions' course catalogs to determine the role
and volume of quantum mechanics in their undergraduate physics programs. All of
the institutions required one course on quantum concepts, 92% required two
courses, and half required three. For institutions with complete class data
(n=56), the quantum curriculum was analyzed using course syllabi. The mean
number of classroom hours spent on quantum concepts was found to be 63.5 hours
with a standard deviation of 28.1 hours. The most commonly taught themes in the
quantum curriculum were the Schr{\"o}dinger equation and three-dimensional
quantum mechanics. However, the Stern-Gerlach Experiment was only included in
28% of the course outlines. Despite current efforts to promote a spin-first
approach, this study found the traditional position-first approaches were still
more common as they were used by 73.7% of instructors.
