Really liked this video because you don't often get explanations of all the jargon from someone who literally researched this and understands all the nuance. Great video!

The explanation of topological quantum computing was both informative and interesting. The use of Legos to illustrate its functioning was particularly enjoyable.

This video is incredible! I spent a lot of time researching Majorana particles and quasi-particles with topological properties, and you managed to explain it all in less than half an hour. You're amazing! Now I can easily explain this topic to anyone. It's also exciting to see how Microsoft is turning physicists' decades-long dream of fabricating these islands into a reality!

Hi, thanks for the great video! I'm an undergraduate student in mathematics, and I aspire to one day become a quantum researchers. During the pandemic, I had been watching materials about quantum computing from Microsoft, and it had been one of my greatest source of inspiration to choose this field of study. I'm glad that despite the hype around AI these days, they still haven't give up on pursuing quantum. Sometimes I feel defeated because of how late I'm coming into this field, but this video has sparked back some of that lost motivation. I won't give up in my pursuit, and again, thank you for the awesome video!

these maps are pure distilled understanding - thx a lot

The best introduction on topological quantum computing I have ever watched so far. Excellent job!!

Describing an electron hole as a quasi-particle (collective behavior) is so intuitive. It makes me wonder why I never heard any of my teachers/professors explain it like that when that's quite literally what it is. Otherwise it just sounds like some wand waving explanation.

Lots of things can be quasiparticles and high school/uni teachers never mention them! Magnons, and phonons are two other examples. There, the specific patterns of movement in an atomic lattice creates waves that can be characterized as particles with specific properties (spin, momentum, etc.) and they can even interact with real particles.

Another QC map! I love these because they help me visualize my favorite aspects of the field into a nice map! Its so clean and intuitive and really helps me organize my thoughts like one of those inspiration boards. Never stop making these maps! This is some of my favorite content on youtube!

Just freaking love this channel

You have a great way of breaking down complex physics concepts 😊

Man you’re good. Loving your work! Keep on making this wonderful videos!

Great video! I finally have an idea of what topological qubits and Majorana particles are. Very well explained, I liked a lot the Lego analogy. Now I have a better understanding of the work my son is doing at Microsoft Lab. Thanks!

Don't take this wrong, but all your videos, infographics, and other information has developed within me my first man-crush! Haha . I love how you chop up all the information into bite-sized chunks, how effectively you boil down the comprehensive study of physics, and how especially interesting you make the information. ❤

EXCELLENT RENDITION, GREAT CONCEPTS!

That was brilliantly explained !! Such difficult , esoteric concepts to convey and put together but you did it really well. Thank you. Really excited now to follow how this develops

This is amazing I am actually doing a PhD and my research involves topological superconductivity and modelling using DFT

Thank you. I sincerely appreciate the time you spent to make this enlightening video.

Good video. Very interesting how this technology is progressing.

Amazing video, thank you for making such a complex (but exciting!) topic so understandable. A treasure! Keep up the great work!!

Love this video and these kinds of videos. I’d had a bit of confusing as to what topological qc was, so thank you!

Really enjoyed this video. Very informative.

Wow, this was so interesting. Thanks!

Great work!

So exciting to see the new development about QC. I have learned the MITXpro course named "Intro to Quantum Computing" last winter vacation and I am really passionate and confident about its future.

I feel like there are two big things here that seem a bit unexplained: 1) So the state appears to be encoded by the parity of the number of electrons between the quantum dots, but this seems very binary (either 0 for even, 1 for odd)… how do you get the intermediate states necessary to be a qubit? My guess is that there is some non-zero probability the electrons are somewhat outside of the quantum dots a la quantum tunnelling. 2) What specific topological properties do Majorana particles specifically satisfy?

Brilliant explanation!

thanks for this video!!

every time you say 'jiggling it' ..... phwoar x

I really love this series. When will we have the map of psychology?

20:42 When you say that the Majorana particles exhibit topological properties, what does that... mean? The Majorana particle pairs are in some mathematical sense shaped differently depending on whether there are an even or odd number of electrons in them? Coming from complex systems theory, we often think of physics and atomic physics in particular as being the domain of both simple complexity, where analytic reduction works well, as well as the domain of disordered complexity, where predicting the motion of a small number of particles is difficult (the classic three body problem), but statistical aggregates generally work to derive the collective behavior of a system from the behavior of individual particles e.g. pressure in gasses or temperature in solids. Whereas it's higher scales where we tend to see ordered complexity where emergent behaviors, well, emerge. It's very interesting to me that at the subatomic level we're back to seeing emergent behavior like these Majorana quasi-particles.

So, electrons odd or even for 2 of the possible states of a qubit, and the 'read-out' doesn't destroy the quantum information? Or it's necessary that the quant info is sent to both ends of the nanowire to not de cohere that info, or is it only to protect against noise? So, they will have another topology for the other states a qubit can be in, and then the combination of the two will work together?

absolutelynflunked my maths exam today but a day when DOS posts is a good day so ir kind of equals out:))

Thank you very much for sharing your insights and knowledge filled videos !! Intelligent and professional !! Outstanding !! Greetings from California … I wish you and folks good health , success and happiness !! Much Love ✌️😎💕

Great presentation - thanks! I'm wondering at about 13:00 what happened to the third "state" of the quantum device. I only see two states, so we're back to a binary computer it seems. I just discovered you through your math poster I saw at my local community college near San Diego, California. I'm going through your channel and site now. Thanks again.

The "third" state, or the difference, would be the superposition of having an even or odd number of electrons, I think.

@mduckernz

12 күн бұрын

The superposition of states is only useful when it’s combined with other qubits, arranged as quantum logic gates. Then the output is the finished product.

So the superposition we are taking advantage of is the number of electrons in the wire?

There’s a fascinating overlap between this idea and thermodynamic computing: in both cases your ‘bits’ are emergent or supervene on collective behavior of more fundamental parts. And in both situations this insures a certain stability or robustness, because, by design, the system ‘wants’ to maintain these collective states. In a sense, it seems likely that we will figure out how to overcome noise and build error-correcting quantum bits by building them ‘from’ the noise itself.

super cool I'll try to do my PhD there

Very nice

Amazing 😍

Hello sir since there are a lot of people from different countries around the world that follow you and want to learn English I hope that you make a vedio about the map of English language.

Mind-blowing

This resembles a lot the development of the blue led. Obviously much more professional

So if i am correct quasi particle are analogous to molecule.

Great explanation (and map), thanks! I know I'm missing a lot here but I don't quite see the advantage of these Qubits. The way you have explained it, they still have only two states - even electron number = zero, odd electron number = one? How does this differ from traditional 0/1 digital binary bits?

Have you seen Extropic's Thermodynamic Computer? Love your channel ❤

but if they only measure if there are odd or even electrons, where is the inbetween?

As good as it gets, 👌

17:46 Why is Atom Computing listed two times?

I have one question. Why we have Majorana particles in the pairs of 2. Why can't we have them as a collection of lets say 20 50 or 100 ?

I highly encourage you to read 'majorana returns' from Frank Wilczek, it is very readible and enlightening

As an aside: While both involve surface-level operations, RPA automates tasks while topological quantum computing utilizes surface electrons for quantum computation.

top notch!

I'm a bit confused how having a wire with some number of electrons on it can work as a cubit, how is that different that having a chain of tiny gates in a traditional computer?

Can this be extended to qutrits ?

Legos are a gift for science and engineering lol. I had to make a presentation about chemical inhibitors for the company I worked for at the time and I used legos to describe the process. It worked great.

Every video I watched about quantum computing explains how such computers encode the quantum bits into physical media (and you did it well) but never explains how they do computation (and imo that's the most interesting part). Are you working also on that? Thanks

So the information of all 3 or 4 q bits is combined in a new form of Information that is spread over a distance into 2 seperat regions that I think i understood. These 2 regions are independent from one another and therefore rubust to noise, i also understand. But if I measure one of the two regions or in other words dissrupt one of the two regions I would know the state of the q-bits because I measured them. I thought that is the problem with q-bits. Noise in my understanding is like measurement and they can only compute when they are not measured. I though they colapse into a state of 1 or 0 when they are measured. In the time they are undisturbed they can be in every possible state and do all the calculations. Or is measuring one of the two regions not telling me anything about the q-bit because it is the combined signal of all the q-bits and therefore doesn't count as measuring them? But if mesuring is not a problem what do we mean by disrupting one of the two regions?

The problems that can be solved on quantum computers can also be solved on classical computers; any computable problem is computable regardless of the computational method used to compute it. What essentialy changes is the algorithmic complexity of the computational method being used.

thats still being debated

Killer video. Obviously you don't want to step on MS toes, as they both hosted and sponsored this video. So there is something I'm wondering still about this topic: your personal opinion. Do you think this tech will make them the quantum computing leaders?

Are majorana particles non-abelian anyons?

7:45 Atom Computing is listed twice.

close but no cigar, in the introduction it was explained that a quantum bit can be more than just 0 or 1, it can be anything in between, and that's what makes it different from a classical bit which can only be 0 or 1 and nothing in between, but then you go on to describe an example of a topological qubit where there is either an even or odd number of electrons in it, well that's either even or odd but nothing in between, so you've lost out on quantum-ness. I think you went too far in dumbing this one down for the audience ?

Typically with qbits the physical system can only be in two states. The low temperature and insulation from the outside world allows the circuit to exist in a superposition of 1 and 0, meaning they’re (sort of) both with some probability that they appear to be a 1 or 0 when measured. To do a quantum calculation they run a set of operation, measure the 1s and 0s, repeat, measure, repeat… eventually they have enough measurements to calculate the probability of the superposition before it collapsed and that’s the actual value of the qbit.

@@mememealsome as near as I can tell you are agreeing with me, the video does not explain this subtlety of quantum computing, and actually very few explanations that I've come across do. I still find it mind boggling that people think quantum computing is efficient when you actually have to repeat the computation so many times before you get a statistically meaningful result.

This video was too short, I have so many questions!

Cant wait to play vanilla Minecraft with it.

is it not massively similar to annealing machines? majorana particles sound like they would be more susceptible to noise vs "atomic" or holy grail qubits, like if D-wave isn't good enough...

Great explanation. Why are we still only interested in 0 and 1 though? I thought quantum computers used 4 states per qubit. I haven’t caught up on this stuff for a few years.

we are in the inflection point of history

Was about to comment, I think I know what they were smokeing when naming "Majorana" a "quasi particle" (nod,nod,wink, wink).... And turns out is the name of the guy who found them

lesss go!

I still dont get how they can have values between 1 and 0 if it only measures odd or even which are 2 states, if anyone can explain it to me I'd appreciate it a lot

9:09 yeah, it is common for atoms to have dislocations, in which an entire row of atoms shifts, which is normal when many tiny balls are next to each other, in this case those tiny balls are atoms

In ONE video release we really went from "the map of plants" to "the map of topological quantum computing".....

Surely there will be a Start-button.

What was your Ph.D in exactly?

Why? Why is it that matter at the edges of the universe appears to move faster then it should (according to modern theory). The simple solution is that there is non visible matter present holding the universe closer together then previously thought. This dark matter would act as a solidifier tying the ends to the middle making it having to keep up even though it has to travel longer distances to do so, simmilar to those death machines in playgrounds where you can go to the middle turntable and then proceed to step to the outer edge to enhance the risk of early neck trauma. Let's try and find some other ways into this phenomenon. The first argument I'll be presenting is a relativistic one. We know there are two ways to slow down time, one is to have a lot of mass, the other is to go really fast. If we want the entire universe to have undergone the same amount of entropy we need some way to compensate for the lack of mass. In order to stay within the same timeframe (implicit positive correlation between entropy and time) the matter at the edges of galaxies has to be moving faster. The second argument I'll be making has to do with the difference between rationality and irrationality. If we want to condense matters doing this rationally is probably your best bet, pretty much the reason why your mom is better at packing than you are. This translates to the positive correlation between matter density and rationality. In other words, matter at the edges of galaxies tends more towards irrationality. For a quick sidenote: the symmetry breaking (irrational) weak force doesn't act on light (strictly), this might clarify why this irrational matter is mostly invisible. Rationality is indifferent to direction, it doesn't really matter how you lay a football for a free kick. This is unless you believe in hitting the ball at the valve for that infamous knuckle effect, which is exactly keeping the irrationality behind the primary interaction surface, letting it act indifferent. But this is all a little to deep, so let's resurface. In principle an irrational object is a lot more unidirectional. Throwing an American football, orientation matters. The irrational shape of the American football allows it to cut the air better, allowing for greater throwing distances. Irrationality allowing for advantages doesn't break the principle of entropy, since any small advantage you gain in one orientation greatly increases the disadvantage of any other orientation. In short: reality is slowed down in two ways, mass and speed. The more rational condensed centers of galaxies are on the side of using mass while the irrational edges are more on the side of using speed. In this way there is at least an inclination towards less entropy.

Quantum physics is not necessarily based on stochastics. That's just the Kopenhagen interpretation. The wave-like behaviour of matter on small scales is far more defining. Mathematically, I would say quantum physics is more like linear algebra ..
