  Disputes on the foundations of Quantum Mechanics often involve the conception
of reality, without a clear definition on which aspect of this broad concept of
reality one refers. We provide an overview of conceptions of reality in
classical physics, in philosophy of science and in Quantum Mechanics and its
interpretations and analyse their differences and subtleties. Structural
realism as conception in philosophy of science will turn out to be a promising
candidate to settle old problems regarding the conception of reality in Quantum
Mechanics. We amend the analysis of three main interpretations and their
relation to structural realism by three well-known informational approaches in
the interpretations of Quantum Mechanics. Last we propose an additional class
of structural realism supported by QBism.
