Both entities describe the same fundamental scientific theory. While 'quantum theory' can be a broader term, and 'quantum mechanics' a more specific formulation, their descriptions are highly overlapping, referring to physics at the smallest scales and the behavior of matter and energy at atomic/subatomic levels. The source text from 'Einstein Biography' (Candidate 5) mentions both 'quantum mechanics' as a pillar of modern physics and 'quantum theory' in relation to the photoelectric effect, implying they refer to the same core scientific concept in this context.
