““What one needs is a quantum mechanical model with a wave function that describes not only various systems under study but also something representing a conscious observer. With such a model, one would try to show that, as a result of repeated interactions of the observer with individual systems, the wave function of the combined system evolves with certainty to a final wave function, in which the observer has become convinced that the probabilities of the individual measurements are what are prescribed in the Copenhagen interpretation.””

About This Quote

Source Lecture: Quantum Mechanics and Consciousness, 2005

Proposes a quantum model linking wave functions to conscious observers, aiming to derive Copenhagen probabilities from repeated interactions.

In simple terms: Attempts to connect quantum theory with consciousness.
