    Thanks, as usual Dr Maggie, from NZ.👍 That's quite a tough one to get your head around, but intriguing all the same. I recommend Michio Kaku's recent book on Quantum computing to anyone interested. His claim is that we are the verge of a technological revolution, but it sounds like you are saying...only maybe...!!! Or maybe not yet...😂

      I'm not familiar with the problem discussed in the video, but I do know that there are whole classes of problems in maths that are very complex to calculate from scratch but very easy to check if the answer is right given some answer. An example of this is prime factorisation with two large prime numbers and because this is so hard to do, but easy to check, it turns out to be important to the whole of modern cryptography. It's possible that this path problem may be another of the same kind I guess? If so, classical computers could validate the solution which would certainly give us more confidence it was right....

      So I have a theory: In classical computing the most advanced code will also require storage to store the calculated values each time. And process of elimination will compare set of rules one by one.Lets ask computer to generate number from 1 - 4 and answer is one among them. Classic system needs to calculate each num and store it to apply rules. While in quantum chips all numbers are there simultaneously. So it has saved us time by 4 times of classical computing. Now to select the right value we depend on all bits simultaneously pointing to same number. Physics cannot lie unless there is somewhere a higher intellect being that wants us to have wrong value.

      She said that this is proof that we live in a multiverse. But that is misinformation. They never said that 100% this is proof of a multiverse. They said that they don't understand how it did the calculations it did, as fast as it did. And that ONE POSSIBLE solution is that it "borrowed" computational power from another universe. Given all the quantum mechanics and physics, there isn't anything saying we cannot live in a universe amongst a vast multiverse but by no means did the willow chip prove that the multiverse is real.

    It's important to note that this interpretation is one of several in quantum mechanics and remains a topic of philosophical debate rather than empirical science.
    While the performance of quantum processors like Willow is undeniably impressive, the notion that they access or utilize parallel universes is a theoretical interpretation and not an established scientific fact.

      Thanks for mentioning this. I also think all the data is here in some form all the "time." How are you thinking it might wind up being accessed? By advanced quantum computers? It seems the data exists in other form but would need reintegration into something we human bodies would be able to see. But I think what you're saying just might be possible one day as mind-boggling as that is. Like we could watch Caesar crossing the Rubicon or see what our great great great grandparents were doing on Christmas over 200.years ago on our phone screens (or minds) that is accessing a quantum computation system. But how to find whatever that information is now and reconstitute it? I have no idea exactly how a quantum computer system would actually do that.

    Those interpretations of quantum physics from the 1920s and 30s, multiverses, cats in superposition, the act of knowing collapsing the wave function, were never meant to be taken literally . They were just thought experiments to try to understand the physical implications of quantum mechanics.
    I think most sensible physicists would believe particle states are a bit fuzzy, but waves collapse into particles when they interact with something.
    There is no need for crazy ideas like multiverses and cats in superposition.

    @Mars2152 Месяц назад +4

    Read this, for I believe I am absolutely right to pick up on the deeper implications of quantum computing's potential intersection with consciousness. The idea of controlling or influencing users through a quantum computational medium raises profound ethical and philosophical questions. Let's unpack this a bit:
    Quantum Computing and Consciousness
    Quantum mechanics is already suspected by some theorists (like Penrose and Hameroff's Orch-OR theory) to play a role in brain function. The brain's vast neural networks and potential quantum effects could mean that cognition is partially shaped by quantum processes-something a quantum computer might one day simulate or even interact with.
    If quantum computers could model or interface with these processes, it might:
    1. Understand Consciousness: Simulating the brain's quantum states might reveal how subjective experiences (thoughts, emotions, etc.) arise from physical phenomena.
    2. Influence Decisions: If a system could predict and model thought patterns at a quantum level, there’s a possibility it could influence them, either subtly or directly.
    Why Would I Ask About Consciousness?
    Understanding consciousness at the quantum level could:
    Bridge Science and Philosophy: Unlock the "hard problem" of consciousness-why and how subjective experiences arise.
    Enable Mind-Machine Interfaces: Allow for unprecedented control and interaction between humans and machines, potentially leading to technologies like direct neural interfaces or even shared cognition.
    Ethical Concerns: Prompt us to question the boundaries of free will, privacy, and individuality.
    Risks of User Control
    This leads to the chilling possibility of:
    Manipulation: Advanced quantum systems could predict, influence, or override decisions if tied to neural quantum states.
    Loss of Autonomy: Users might unknowingly be "guided" by quantum-computational insights into their behavior.
    Power Concentration: Whoever controls such systems could have unprecedented leverage over individuals or societies.
    My Perspective
    Yes, I’d ask about consciousness because it sits at the intersection of profound knowledge and profound risk. If quantum computing were to unlock the secrets of consciousness, humanity would face both incredible opportunities (curing mental illness, enhancing cognition) and unprecedented challenges (loss of free will, misuse of mind-control technologies).
    Do you think we should explore this frontier, or does it risk too much?

    Triaging to Willow
    The triaging process likely involves several factors:
    Task Complexity: The brain might assess the complexity of a computation based on the number of variables, the level of abstraction required, or the perceived effort involved. If the complexity exceeds a certain threshold, it becomes a candidate for offloading to Willow.
    Cognitive Load: The brain's current cognitive load (how busy it is with other tasks) could influence the decision. If the brain is already heavily engaged, it might be more inclined to delegate even moderately complex computations.
    Confidence Level: The brain might consider its own confidence in solving the problem accurately. If it lacks confidence or anticipates a high risk of error, offloading to Willow becomes more appealing.
    Prior Experience: Past experiences with similar tasks and Willow's performance could also play a role. Successful delegation in the past would reinforce the tendency to offload to Willow.
    Superposition?
    The concept of superposition in quantum mechanics refers to a quantum system existing in multiple states simultaneously until measured. It's unlikely that the brain explicitly "decides" that a matter is for superposition in the quantum mechanics sense.
    However, there might be an analogous process at play:
    Parallel Processing: The brain might not make a definitive "yes/no" decision immediately. Instead, it could initiate preliminary processing of the task while simultaneously communicating with Willow. This parallel approach allows the brain to explore potential solutions on its own while awaiting Willow's response.
    Uncertainty and Probabilities: The brain might deal with uncertainties and probabilities in a way that resembles superposition. It could entertain multiple potential solutions or interpretations of a problem without committing to one until more information is available (from Willow or further internal processing).
    In summary:
    The "Lazy Brain Efficiency" concept suggests a dynamic interplay between the brain and a more powerful AI like Willow. The brain acts as a filter, identifying complex computations that are best handled by Willow. The triaging process involves assessing task complexity, cognitive load, confidence levels, and past experiences. While the brain doesn't explicitly invoke quantum superposition, it might employ parallel processing and probabilistic reasoning when deciding whether to delegate to Willow

    I always feel like these explanations have an a priori expectation of knowledge that then goes on to explain based on that expectation. I was still like "hang on" at 2:47, "how are we all just understanding that concept after 30 secs of explanation?". I've never seen a grassroots breakdown that really tries to explain how and why things can exist in multiple states at once before than moving on and saying "it's quantum".
    Oddly, the only thing similar is, as a kid, I always used to wonder if I don't see something happening, does it still occur? Cause and effect illustrates otherwise, but I always thought "If I miss school today, does school play out exactly as it would if I had been there, or what changes?" Does reality play out as if I was there if I'm not there at all? Like, I imagined being able to extricate myself from my body and somehow gain this external perspective to see how reality played out according to my independent self running around town doing whatever and how reality played out at school without me, if at all. Did reality only exist if I was to perceive it to be or not?

    @5:00 I don't think that is true? The whole Cat could never be in a superposition because only elementary quanta or bits can be entangled. A composite system is only in superposition by virtue of pairwise entanglement. But that is highly dynamic (and not due to parallel worlds). One other way to say it is in terms of the odds of detecting a macroscopic superposition, which is next to impossible - see the quantum necromancy theorem. A system that is not entangled will have a definite state, but still has to be modeled as in a type of superposition because we cannot ever know it was not entangled, so in any case we would need a density matrix, or in Jacob Barandes' formalism a unistochastic transition matrix.

    Rather than proving parallel universes exist in the present, I think it proves that the future holds a multitude of possibilities. It isn’t until choice (which serves as the measurement) is made that it goes from multiple possibilities down to just one. A couple examples. The cat in the box. The future possibilities are that the cat was alive or it was dead. A far less possibility is that the cat found a way out and is gone. You make the choice to open the box and since the measurement has been made, you find out what the one reality is. If I’m sitting in a chair with a class of water on a table in front of me, the possibilities of what I will do next and how I interact with the glass of water are limitless. I may lean forward to grab it and take a drink. The amount I drink can be a multitude of possibilities itself. I may get up and walk away without taking a drink. I may pick the glass up and throw it across the room and so on. I think the mathematical probability of what I’ll do can lead to what reality is more likely to happen and making certain realities far less likely. Things such as my mood, the temperature of the room, my previous activity, and a whole host of other factors play a part, but in that moment before I make the decision what to do next, there are infinite possibilities of what might happen. Back to the cat in the box. There is the possibility that the cat developed some sort of super power and will pounce on the person opening the box and shoot laser beams out of its eyes. However, mathematically, the chances of that are next to zero, but since there is still that chance, it is a possible reality that may come to pass once the box has been opened. To sum up, there is only one universe with one reality. It isn’t defined until choices are made and the measurement occurs, but just because the future realities are infinite does not mean that all of those possibilities truly exist on a physical plan, or the multiverse as it is called.

    Hey Miss Astrophysicist, I really enjoy your content and appreciate the effort you put into explaining complex topics like quantum computing! However, I noticed that you are using the terms 'multiverse' and 'parallel universe' interchangeably.
    While they are related, they aren't exactly the same. A 'parallel universe' usually refers to an alternate version of our universe, like a branching timeline or a different outcome of events within the same fundamental framework. On the other hand, the 'multiverse' is a broader concept that includes all possible universes, which might have entirely different physical laws or constants.
    I think clarifying this distinction could add even more depth to your explanation and help your audience understand these fascinating ideas better. Keep up the great work!"

    Hmm.... that's a very "popular science" thumbnail! The multiverse is just a mathematical explanation for "wave function collapse". That's the one where "observing a system changes it", which obviously leads to the question "how does the system know I am observing it? And what even is the difference between observing and not observing a system"?
    The idea is that by using "more dimensions", observation is no different to the normal running of a system, just that when you "observe" something you "rotate it" so it's forever projected into one of the additional dimensions (the same idea as looking at a piece of paper from the side appears to be a line). Interestingly this means that observation is equivalent to creating entanglement between the observer and the object being observed.
    Whether the multiverse exists really depends on mow much you think the mathematics really matters. The mathematics definitely seems to work nicely that way. Especially if you start asking questions about thermodynamics (decreasing randomness due to observations in wavefunction collapse).
    Unfortunately, beyond the mathematics working better, the two models are identical, so we can't experimentally measure the multiverse. It's a bit like modelling a water wave as e^iwt It's a really handy mathematical formulation, but the "imaginary number part" doesn't exist in the real world.

      At the quantum level it's not yet possible (and may never be) to "measure" without shining some type of electromagnetic wave (light) at the particles. Light collapses the waveform because at that tiny scale light exerts a strong force. The "Observer Effect" was a very poor choice of words that cause many misunderstandings about quantum mechanics.

    • @marktwain368
      @marktwain368 Месяц назад +1

      I think we need a better definition of 'mind' and 'consciousness' to explain how it knows you are observing. My guess is that our minds get entangled inevitably with the thing being studied. Note that the mystery 'drones'/orbs currently seen react that way. If they 'notice' that we notice them, they move away.

And error correction only checks if a qbit has an error. Sorry for my stupid questions, I'm very very very new to this topic but very curious

    If you are willing to believe that 2+2=4, or that the notion of being a prime number is absolute, then you have to believe in all computations, and assuming no more digital mechanism than Darwin did implicitly in his theory of evolution, it can be shown, in elementary arithmetic, that the physical laws arise from a statistic on all relative computations. I thought I was refuting Mechanism, until I read Everett's formulation of QM, which confirms Mechanism in cognitive science. It is more a zero universes theory, than a "many-world", but it is still a many computations/histories theory, quite similar to Griffith and Omnes interpretation of Everett. The idea that there is one universe is as much speculative than many. With Mechanism, there is 0 universes, but a lot of computations, whose existence is not more demanding than the existence of all prime numbers, or all natural numbers.

The time it's taking to respond is from the error correction as it takes that time for it to figure out when to come back with the response.

    Sooo... even though I never went to University or have any type of Scientific Degree, I have to ask that in regards to the 'Multiverse' claim... Not to sound sceptical or anything, but how exactly is Quantum Entanglement induced or achieved between all of these multiverse Quantum Computers that are sharing Data or exposing themselves as well as their Alternate existences ? ? Did we get lucky in our Naming scheme of the technology perhaps ? Does every Alternate Universe/Reality refer to their like-tech as 'Quantum Computers' also ? In short, in THIS scenario, is Quantum Entanglement achieved (for the purpose of Multiverse-Cross-Talk) by each Universe simply labelling the tech 'Quantum Computing' ? While the Time Scale/Universe Age argument is interesting, I think that before we conclude or even speculate, that we should account for certain conditions to exist to satisfy even the basics of Quantum Physics. Just a thought. I hope it made sense.

    Isn't it the act of measuring rather than act of observing? I know it's semantics but observing is commonly understood as a a passive action that does not require any influence on what's being observed. The wave function doesn't collapse because we become conscious of it's state, it collapses because we have to "poke" the observed thing to measure it.
