That makes way more sense than being in multiple states. An electron could absolutely be moving 30% left and 70% right if it's moving 100% in a vector that can only be calculated by us to be 30% left and 70% right. Once we launch it against something to see if it's 100% left or right we knock it into one of those. I suppose an interference pattern could then be caused by blocking a specific range of vectors it could be following causing any that would be moving along those to change directions, and while it looks like it's interfering with itself reality is that we merely blocked a vector range that makes it look as such.

"Particles can phase in and out of existence spontaneously!", "information can travel faster than the speed of light!", "consciousness is somehow intrinsically linked to physics and collapsing the wave function of a double slit experiment actually supports quantum theory!" ... Those sound like fantastical claims to me, and you taught me better than that.

The best explanation of superposition ever. I am interested in quantum computing and no one has made plain where the many many possibilities derive from. This makes it crystal clear. Thank you and please continue the outstanding work.

Bohr's philosophy physics, if you really get into it, allows you to intuit the nature of this phenomenon really, really well. Nick, you did a great job at breaking down the primary misconception in popular parlance about superposition, but when you really dig into what Bohr was trying to espouse during the birth of this whole field you realize where most people lost the plot, especially anyone who ever said "shut up and calculate". Yes, particles are only in one quantum state at a time, best represented by the vectors of a probabilistic wave function composed of a superposition of complex states, but the POINT, is that those states are ONTOLOGICALLY, not epistemologically, complementary. The Heisenberg uncertainty should have been called the indeterminacy principle because it has nothing to do with our inability to NOT KNOW, and everything to do with complementary features of nature that form reality having mutually exclusive effects on the rest of nature upon each interaction, creating meaning only BY INTERACTING, meaning that quantum particles are not things as we understand them but are more so phenomena constantly in the process of manifesting through their relation to everything around them. To think about particles as deterministic objects with objectively defined characteristics at all times is to misunderstand the instructive lessons of QM. When a detector of any sort measures a particle, it is physically interacting with it, and the differences between the experimental set ups required to enact differential cartesian "cuts" between the observer and the observed, fundamentally exclude access to information about the complex makeup of the former quantum superposition. The crux is that this has NOTHING to do with humans, or our experiments, or our theories. That would make the question of what happens in quantum superposition and afterwards about our knowledge. The complementary nature of quantum phenomena extends to every piece of universe itself. We are not special because we've figured any of this out. All the detectors we use to probe nature are made of nature, it's all the same STUFF. Between the interactions of countless particles that "decohere" to form our world, the universe finds itself excluded from the totality of information about states before and after they've interacted. Someone else below in the comments asked if the orb stays rough or smooth after measurement. If you take this to heart, you immediately understand that the wavefunction begins to smear once again after measurement, and traverse the phase space of possible vectors, until the next "measurement" forces an interaction, and again, and again. There are reasons why you could expect a smooth orb to stay smooth time and again, but its not because it IS smooth outside of an interaction to manifests that smoothness at a scale at which we can read in our medium sized world. This was proven in one of the landmark experiments that Bohr and Einstein could have only wished they'd lived to see: Bell's Inequality, which demonstrates that quantum particles are indeed indeterminate between interactions. Quantum superpostions ARE something singular (if they weren't their probabilities would add to more than one) but that something is probabilistically undefined whether we're looking or not.

You're the first person to successfully explain a quantum superposition to me, "successfully" meaning that I (think I) understood. Thank you very much for that!

Love ❤️ your channel & presentations!

Hello. This was one amazing video Nick. You really put a lot of thought into this and it shows. I think I have never seen a better explanation of the topic anywhere. If I had this in university I could have understood this many years ealier than I actually have.

That was the coolest explanation about double slit experiment and wave functions I ever seen!

By far this is the best superposition video I have ever seen, thank you so much for it, Nick😊

I'm so glad I found your page!

A very clear and lucid explanation! I always hated the concept of Quantum particles Superposition meaning multiple positions at the same time.. this video is a real eye opener giving a clear concept. So far I have not seen anyone doing this before. That is truly awesome! I also love your unique concept of clones and adding a little humor. Thanks a lot Nick!

Great video, this reminds me why I love physics. More specifically in the case of QM, learning weird stuff that puts into practice what I've learnt in linear algebra and probability.

This is the best video about this topic I've ever seen. It made me feel like I could understand it a bit better and I don't have to be satisfied with the explanation that quantum mechanics is simply strange and not really understandable. On top of that, your videos are so interesting and funny, it never gets boring to watch them. And by the way, your pronunciation in German is absolutely well.😁 Greetings from a crazy girl from Germany!

For the uninitiated mathematicians watching, the "Hilbert" space used to represent quantum states is actually a *projective* Hilbert space where the "ket" vectors have unit magnitude/norm. This is done so that when the dual-space "bra" vectors are used to create inner products, such inner products yield values having complex magnitudes less than or equal to 1. Norm-squaring these inner products give probabilites as shown in the video.

@noobyfromhell

2 жыл бұрын

The projective Hilbert space model also gives us global phase invariance, because in addition to normalizing the vectors (which gives you a hypersphere) you also need to take a quotient by the action of U(1), which gives phase invariance.

Minor correction: It's just the norm, not the norm squared. The norm is itself the square of the magnitude.

@Impatient_Ape

@@JivanPal When you compute the inner product of an input state ket with a bra that represents an output state vector, you need to multiply their inner product with it's complex conjugate to obtain a probability of that outcome. The norm is the magnitude of the inner product. The "norm-squared" gives the probability.

Wow, very eye opening. Thanks so much for taking the time to make this fundamental info relatable to us pleebs.

Now uv made it clear ...i always wondered how a particle could be in a superposition...nice narration

That was amazing, thank you! And super impressed that when I checked your vector example, it still had unit magnitude. You’d be amazed how many KZreadrs would fail to achieve that. 👏

Thanks! Attention to detail is important to me. (To be fair though, I do occasionally miss things.)

I find polarization of light to be more intuitive to understand when it comes to superposition and the fact that a superposition is a single state. But this example really helped me get away from the idea that the properties in superposition must have some interpretation in spatial dimensions.

thank's Nick, superb explanation. I don't know if yours is the best way or not to explain quantum phenomena but at least yours is the most vivid one so far.

Thank you so much! I've watched multiple other videos and read lots of different things and it never clicked. Finally I can understand superposition (somewhat since you can't really ever understand anything fully in quantum mechanics)

The best explanation of superposition that I’ve ever heard. It’s clear and insightful.

Thank you. I love your videos, and I love that you add “without woo woo” at the end. Similar to your video on Hawking Radiation, you take the approach that your viewers aren’t morons, but that they’re probably too busy to sit down and figure this stuff out. You do a fantastic job of taking away the “Quantum Mechanics knows that humans are looking” hype, and actually give a person an impressive intuitive understanding for how this stuff works. You should do a lecture for the layman that wants a deeper mathematical understanding while also adulting at the same time, I would travel just to see it!!

I think it really comes down to how you define a “state”. Of course the system is always in a single “state” however complex that state might be. But we can also see the state as the combination of several states. That is what we call “superposition”. More or less, a quantum particle is always in a superposition, whatever state it’s in, due to the uncertainty principle. However, there exists the simplest, most statistically accurate state that cannot be seen as the combination of simpler states. That is the ground state of QHO, which meets the limit of uncertainty principle.

@Lucky10279

His point is that a combination of multiple states is still one state. In the same way that, e.g. wouldn't say that 10 is multiple different numbers just because 10=2+5=1+9=8+2, etc., The sum of two states is still one state. Or, perhaps more aptly, even though a vector can be written using two scalars, it's still just a single object. It's like the velocity vector he shows at 5:54 -- you can break it up into two other vectors, one on the x axis and one on the y axis, and that's totally mathematically valid, but it's still just one vector and there's still just one velocity.

Thank you for making this video. Quantum superposition is probably one of the most mystified concepts in all of QM in popular science texts and videos, even though it's literally equivalent to the superposition of vectors that anyone who's completed high school mathematics should know.

Nice to see the complex metaphor of using math to model physics explained in detail, helping everyone to not be confused when projecting expectations using those metaphors. Kudos.

It's the first time that I see your chanel and I think that your explanations are great. New subscriber :D

As someone with a limited background in modern physics (electronic engineering degree) but an insatiable fascination acquired later in life, I'm constantly consuming "physics for dummies" content. For me, most of it is repetition at this point, so my hope each time is that the content provides some new way to think about a difficult concept - something I haven't already read or heard a hundred times. That way there's a small chance that I'll gain a tiny sliver of new understanding. To be sure, it's an inefficient way to learn, but when it happens, it's SO satisfying. This video is an example of such content. Thank you so much, Mr. Lucid!

Thank you so much. Everyone forgets that the probability in quantum physics comes from having multiple possible states that could result or would still produce currently observed reality. And when we measure it, we'd change the state such that we couldn't really be sure which state the particle was in when we measured it.

Indeed, I have the same problem when people saying of a thought experiment that we can 'see' this spaceship travelling at such and such a relativistic speed. Are we talking about the actual passage of photons from the ships to our eyes, or something that we could measure if we could somehow 'find out' what's going on without the complexity of.light having to 'get" to us ?
