  This is a philosophical paper. It claims that there is a gap to be filled in
the relationship between complexity theory (CT) and quantum theory (QT). This
gap concerns two very distinct understandings of time. The paper provides the
ground for filling up such gap. Indeed, most works on complexity at large focus
on the macroscopic world, leaving behind the importance of the microscopic
world. This paper specifies what both worlds consist of, and argues that a
solid account of the world, i.e. complexity, must necessarily take into account
both dimensions of reality.
