Abstract

The advance of QBism over other interpretations of quantum mechanics is that it introduces the first-person perspective and treats quantum theory, including the Born rule, as a norm. The problematic nature of this position (subjectivism, relativism, residual dualism, etc.) stems from the fact that it remains within the assumptions and prejudices of modern philosophy, including when it is interpreted phenomenologically. Cubism, however, can be transformed into contextual quantum realism (CQR) - a consistent and genuinely realistic position - by reinterpreting its basic notions, particularly the notions of reality, experience, agent, quantum norm, quantum probability, and others
