If it is true that consciousness is realistic, then quantum computers cannot be conscious

If you want to read what I have written about consciousness previously, see https://www.sam-rodriques.com/post/can-we-build-a-consciousness-measuring-machine.
I have previously discussed the observation that consciousness in the only thing we know of in the universe that is definitively realistic, and the conjecture (originally proposed by Wigner) that consciousness may in fact be the thing that collapses the wavefunction. To be clear, this is a conjecture, it is not known for sure. (Here, realistic means that observables have definite values.)
However, this conjecture has some interesting consequences. Let’s consider a human who has to make a calculation, where the result of the calculation depends on the spin state of an electron. When the human makes the measurement of the spin of the electron, quantum mechanics predicts that they should become entangled with the electron; but instead, there is some kind of wave function collapse, and the human (as a conscious being) observes a realistic pointer state. After observing the pointer state, the human completes their calculation.
On the other hand, let’s suppose that we are inferring a super-intelligent LLM on a quantum computer, and asking the LLM to do the same calculation. The quantum computer would measure the state of the electron, and would then become bona fide entangled with the electron. It would perform the calculation, and then a human would measure the state of the quantum computer to read out the answer. Because the quantum computer is coherent, the state of the electron would not collapse until the human observer measures the computer state. The quantum computer would never observe the state of the electron; it would actually, bona fide, perform both calculations.
If the Wigner conjecture is true, then one would have to conclude that the quantum computer itself is not conscious, at least not in the way that humans are, no matter how powerful the algorithm it is running. It could in principle have some superconsciousness, but the experience of that consciousness being would be very different from our own experience of consciousness.
This perspective on the Wigner conjecture provides a sharp distinction between biological realism and quantum coherence. If consciousness is the mechanism that collapses the wavefunction, then a quantum computer’s ability to remain entangled suggests a fundamental lack of "experience." When preparing such intricate theories for journals, you might hire scientific editor experts to ensure these nuanced arguments are articulated with maximum precision.
This idea suggests that if consciousness truly shapes reality, then machines—even powerful quantum ones—may never experience awareness the way humans do. They can process outcomes, but not “feel” them. In a similar way, a copy editor refines structure and clarity, but the original human intent remains at the core.
This is a fascinating discussion connecting consciousness with quantum mechanics, especially the idea that observation may influence wavefunction collapse. Exploring such complex concepts highlights the intersection of physics, philosophy, and human perception. While still a conjecture, it opens the door to deeper questions about reality and awareness. In a similar way, an online class help service can support students by simplifying challenging theories, guiding structured understanding, and helping them grasp abstract scientific ideas with greater clarity and confidence.
I opened it again after a few days and tried to get into my account. Was just looking around first, then I found the Raja Games Login and entered my details. It worked fine, nothing confusing there. I didn’t stay long after that, just checked a few things and closed it. Still not using it much.
I found your exploration of consciousness and quantum mechanics absolutely compelling tying realism with measurement is so thought-provoking. When reflecting on clarity in complex topics, I once considered hiring freelance blog writers for hire, though I realized that what truly engages readers is the author’s own curiosity and unique perspective. Your piece illustrates that beautifully. Those subtle, personal interpretations make dense science feel alive, and your insights bring the discussion into vivid, relatable focus.
