  • Testing consciousness causes collapse: an interview with Kelvin McQueen

In episode 33 of the Quantum Consciousness series, Justin Riddle interviews Kelvin McQueen on his recent theory on how consciousness might collapse the wave function. Kelvin is a professor of philosophy at Chapman University who investigates the nature of consciousness and role it might play in quantum mechanics. The measurement problem in quantum mechanics is that there is a smoothly and deterministically evolving superposition that is abruptly “measured” and reduced to a finite physical state, but it is unclear what constitutes a measuring device. In collaboration with David Chalmers, Kelvin explores the hypothesis that the measurement device in quantum mechanics might be consciousness. However, consciousness is typically an ill-defined vague idea that does not produce any tangible upgrade to the mystery of what a measuring device is. Here, Kelvin uses the definition of consciousness from integrated information theory (IIT) by Giulio Tononi. Consciousness is the minimally reducible information state of a system, which is defined as a recurrent network of interconnected nodes that predict the next state of the system. According to Kelvin, this definition allows for testable predictions to be made regarding the role of consciousness. In the upgraded quantum IIT theory, the nodes are quantum bits (or qubits) and the edges are entanglement relationships. Thus, QIIT defines an interconnected quantum computer (of sorts…) as consciousness and this reduces the wave function. Furthermore, the collapse of the wave function is not instantaneous but instead is continuous, drawing from the continuous spontaneous localization theory of quantum mechanics. Altogether, these ideas present a picture where consciousness is integral to a fundamental description of the physical universe and might provide room for an expanded sense of self. In this interview, I interrupt intermittently to describe the relevant ideas with graphical representation and compare this model to the Orchestrated Objective Reduction model by Stuart Hameroff and Roger Penrose. There are some amazing new ideas that Kelvin McQueen describes in this episode, so be sure to check it out!

Hi, They are interesting correlations with the works of Penrose and Hameroff. The fact that this consciousness originates from the quantum level and neurons and these microtubules is a relevant road.
Now of course the problem is our philosophical , mathematical and physical limitations. But the model of Penrose and Hameroff permits roads to better understand the free will also.
When I tell that the problem is also philosophical it is the same for our deep unknowns like the quantum gravitation and others. We return always at these limitations , that is why the origin philosophical of this universe becomes the key , if we consider only this GR like cause of our QM , so we must admit that it is an assumption, we have the QM and this GR and we measure and observe emergent properties and these 2 theories work well in our referentials of observations. But the QM could emerge from deeper causes and informations .
If the quantum processing is a key for this consciousness and that the theory of informations must consider deeper informations and parameters, so the computable quantum process seem not computable at this moment due to these parameters hidden. The collapses of the waves fucntion like in the model of penrose and hameroff permitting these non computable algorythms. It is mainly about the non randomness . That said these limitations philosophical are the main key because we cannot affrim that these collapses and the spacetime curvature and actual quantum known processings permit to reach this consciousnesss.
The microtubules and a kind of computation of these mechanisms are limited due to fact that we observe the surface of causes but not the main causes and their complexity at this quantum level. It is the reason why the philosophy of origin of the universe is important to know and these deeper scalar fields probably.
