  In this article we present a possible way to make usual quantum mechanics
fully compatible with physical realism, defined as the statement that the goal
of physics is to study entities of the natural world, existing independently
from any particular observer's perception, and obeying universal and
intelligible rules. Rather than elaborating on the quantum formalism itself, we
propose to modify the quantum ontology, by requiring that physical properties
are attributed jointly to the system, and to the context in which it is
embedded. In combination with a quantization principle, this non-classical
definition of physical reality sheds new light on counter-intuitive features of
quantum mechanics such as the origin of probabilities, non-locality, and the
quantum-classical boundary.
