ABSTRACT
Syllabus and Recommended Literature
This tech talk series explores the enormous opportunities afforded by the emerging field of quantum computing. The exploitation of quantum phenomena not only offers tremendous speed-ups for important algorithms but may also prove key to achieving genuine synthetic intelligence. We argue that understanding higher brain function requires references to quantum mechanics as well. These talks look at the topic of quantum computing from mathematical, engineering and neurobiological perspectives, and we attempt to present the material so that the base concepts can be understood by listeners with no background in quantum physics.
In this third talk we review the history of the theory that quantum effects are essential to understanding brain function. We look at the theory of Penrose and Hameroff and its refutation by the decoherence calculations of Tegmark. Our experiments with pattern recognition using a quantum computer teach new lessons on which type of problems the brain may solve by quantum processes and how the data flow might look. Specifically, we conjecture that computations that are not time-critical and which require the solution of a global optimization problem are good candidates for brain processes facilitated by quantum phenomena. We then study situations in which coherence could be maintained to be of behavioral relevance as well as recent findings that show the relevance of coherence in basic biological processes such as photo synthesis and enzyme function. We advance a speculative theory that mental states induced by tryptamines might come about by enhancing the propensity of the brain to relegate certain computations to quantum annealing. We argue that by virtue of being a physical substrate the brain exists in a global superposition with the environment and participates in information exchange via fundamental physical interactions. This regime becomes relevant in situations in which neural dynamics is less driven by sensory input or behavioral affordances. Studying multiple corpora of reports describing experiences mediated by the psychoactive brew ayahuasca, we argue that our model outperforms a more mainstream neurobiological explanation based on neural assemblies.

LOL what's funny though is that the particles seem to know when your trying to measure them than they disappear like they have their own intelligence.
it's because we create our reality through thought, we think of measuring particles, and then we can measure them, because we have created the reality of being able to measure them, when we are not thinking of them, they become possibilities, and are not in one single position, until we measure them.
I imagine this is something science will never figure out, until they come to terms with the fact that we do create our reality. then it will make more sense, right now, it's madness to them.
I'll explain quantum computing using binary code. As we all know binary code is either a 1 or 0. With quantum computing their are 3 spins that the electron can be in. A spin 1 state, spin 0 state, or at both spin 1 and 0 at the same time. Lets take an example with three bits, obviously their are 8 combinations that the computer must cycle through to process them, with quantum computing, having both states at once means 1 line of code can process all 8 states in one processing cycle vs 8.
No actually it's correct, that's why quantum computing is super fast compared to normally computing. The fact that you are using electrons in both 1 and 0 spin states means that you can represent 1 and 0 at the same time in that state. Lets say you wanted to represent all binary combos from 0000 to 1111, normally their are 15 processes needed to display as you need to move to 0001 than 0010 so on, with QC you can in one process represent all 15 binary combinations at once. Read QC books buddy.
He compares two boxes, a 'quantum' box that we don't understand and a 'classical' box that we don't understand either. He then proceeds to argue that the effect of certain drugs fit the quantum box better than the classical box. But how can you argue this without a physical or at least computational description of the box? Now it just depends on how much magic you assign to each box.
I agree the discussion needs to get back to a small set of neurons.
oh, and ill quote myself as some google fanboys downvoted my statement of pwnage:
Scientists have most recently proven that thoughts and decision are formed up to 10 seconds before the person even becomes aware of them. Quantum states are not stable for 10 seconds.

why not then generalize instead of perpetuating bullshit species-centric thinking ingrained in most imperial western minds ???
ewmunn ...
