How To Code A Quantum Computer 

And you misspelled the name like everywhere, I got confused, because you pronounced it differently, so I looked it up too xD

Instead of a list of bits/bytes, try a superimposed number wheel/magic square. Kinda like wheel of fortune. But each number has its own wheel. The "number" is defined by the difference in positioning of spin, #2 starts "spinning" .10 seconds after #1. Kinda of like a substitution cipher. The code is gibberish without a unique custom "key"/"perspective"

You're forgiven ,😅❤

i noticed too that

Awesome content. Big ups ↑↑ all the best.

Lol😂

😂 A good one.

I called quantum IT support and complained my computer isn’t working. But then when I looked at it again, it was fixed! :D

They said in thieir parallel world, it seems working just fine

"I tried, but it was neither here nor there."

I’m glad to hear it! This kinda stuff is hard for everyone - definitely took me multiple passes before I understood what was going on.

@@Lukas-LabI must disagree with @tongpoo8985, that I didn't understand one qubit of it. But I picked up a "vibe" from the 1970s/1980s, when Bubble Memories were going to change the world, the storage space and what not. A lot of money and research went into it, things "worked" but never scaled to be actually useful, and within 10-15 years the technology had mostly been forgotten. I get the exact same vibe about quantum computing... Maybe I am just a Luddite, but I seriously doubt that the scaling challenges will be solved, and instead something different will accelerate past it.

Honestly that’s totally fair. It’s hard to say whether quantum computing will end up changing the world. The important thing is that it has the capability to, which is why I research it. I wouldn’t work on it if I didn’t think it had potential. But it’s totally possible that it doesn’t reach commercialization.

Thanks! I hope you’re right:)🤞

I am actually sick of watching 🦀 , This video is little breeze of fresh air , just a little , Because I already knew about it beforehand QC content is amongst the most of abused content Followed by Einstein 's all 🦀

Been watching a lot of these to understand larger thought problems and warp drives

Wow, thanks! That’s great to hear :)

Same hear bro, I was looking for this. But, idk what to do with this knowledge. Whatever, the more you know

Well this is kinda interesting I made something that is basically an input counter that uses binary but the memory storage is structured as pascals pyramid which basically means that I have the input of 1 and 2 already which is 4 basic 2 bit adders that is basically just 2 t flip-flops and an xor as well as an and gate but hooked up in a way so that each input goes into each and the outputs don't interact with each-other and then I basically hook it up to a bunch of and's in which there is already 4 2's but you need extra for the horizontals Which would be for the extra 2's. then you do the higher numbers like 3 and 4 all the way until you get to 8 with a whole bunch of and gates which would be for memory because basically you have all the previous 1's and you would have to hard-wire them to each and gate individually. Well in the game i'm in basically and then you would use or gates to have each form of 2 inputs by a 2x2x2 cube of t flip-flops basically encoded as 2 for all of them. Which then you would use xor gates in which you would input the or gates into as an input which would capture all the numbers then use the xor gates from the highest row of each number to cancel out the lower numbers. So basically its an adder that has memory in the form of and gates and the input interface is a 2x2x2 cube of t flip flops. And if you're wondering where pascals pyramid is in reference for this memory based adder. Well its in the inputs of and's for every single combination of the 2x2x2 cube in which each and is a different value. And if you're wondering about the game. Well its called circuit maker 2 on Roblox of course. and the xor gates are to find every input of odd 1's basically the signals that are on but if it find's an odd number of signals that are on then it outputs a 1 and if it finds an even number of 1's it outputs a 0 basically turning off. And for the and gates you basically have all the inputs set to 1 and so if a certain combination of inputs are set to 1 you can basically hook up those inputs into an and value and then you have a certain pathway for that bit of memory which is how I made my adder work. It's very simple actually and I think it's something that would be a bit difficult to do precisely because it would be tedious to set all the wires and ect. Also anything with a n like a nand gate or a nor gate is basically the opposite of the other gates. Also the sequence because I hooked it up to xor gates made it have significantly less memory that I have to use primarily because it cut all the 8 one values by half making it so that I can have the values of 1,4,10,16,19,16,10,4,1 instead of 8,20,32,38,32,20,8. and then if you want to expand it you basically have the same adder module and then double it and then you wire them together with a bunch of and's and then use a bunch of or's and xors afterwards to make something that would add base 10 integers that would be for every combination of 1 and 8. Which then would be 1,1. 1,2. 1,3. 1,4. 1,5. 1,6. 1,7. 1,8. 2,2. 2,3. 2,4. 2,5. 2,6. 2,7. 2,8. 3,3. 3,4. 3,5. 3,6. 3,7. 3,8. 4,4. 4,5. 4,6. 4,7. 4,8. 5,5. 5,6. 5,7. 5,8. 6,6. 6,7. 6,8. 7,7. 7,8. 8,8. Which each and value would be of storage for the on's of those specific numbers.

Thanks so much, this really means a lot!!

1 month keep going

initially cs is very difficult to learn, but with time it becomes easy, so don't give up at initial stages

How's going?

@@shamanthrs1284are there rly ppl this is easy for?

I’m glad this video was helpful!!

Thanks for the comment man, things like this is why I love to make videos :)

Thank you! That means a lot :)

Yep this is all true - it’s just that if I were to cover all of this in a video intended for a general audience the video would be way too long and detailed. This is all information I would include in a detailed course lecture for example.

To do quatum computing i choose EE and moderne physics or CS and Moderne physics

Thanks for the support, I put a lot of work into these videos so I really appreciate it :)

Agreed dude wonderful job, if you were testing the waters here keep going because you explain it well and are a great teacher, great video(s) subscribed​@@Lukas-Lab

Glad it helped!!

Yeah, you’re probably right here. I thought it would be clear that the first qubit is the one initialized to 0 and the second is the one initialized to 1, but I should’ve explicitly stated that. Thanks for pointing that out - I’ll make sure to keep better track of that in the next video.

I totally agree, problem is this is a channel for a more general audience. While I’d like to go deeper into the linear algebra I want to keep the videos approachable so that more people can understand. At the end of the day my goal is more to get people interested than to get people to know exactly how to reproduce the algorithm, there are great instructional videos I can link if people want to learn that as well.

He's right, I barely understood all you said and I feel bored.

Thanks so much! I’ve taken a lot of inspiration from his videos and style.

@@Lukas-Labhe’s not joking lol I genuinely thought this was done by a huge stem channel like 3blue1brown. I also don’t leave comments, but felt like you should hear it

That’s awesome! Yeah - I’ll probably do deeper dives into each type of qubit later on, although I don’t have any immediate plans for that.

Awesome! Thanks for tuning in!

If you'd like to learn about how classical computing works check out Ben Eater. He starts by explaining how semiconductors work and then works his way up through logic gates and microcode and eventually has a working computer built up one piece at a time. If you want to learn more about quantum mechanics, well... PBS has some good science content, and you can find some of Feynman's lectures as well. It's a difficult subject to come to grips with, though. If you'd like to learn more about quantum computing, this video may actually be the best thing you can find without spending money, at least for the time being. There's an old video on the Microsoft Research channel called "Quantum Computing for Computer Scientists", but it mostly just covers the same material in-depth without the visuals and assumes that the viewer was already familiar with the material a bit. It sounds like Lukas has a second video, though, so that would go beyond what the MS video covers.

Thanks!

Thanks! I really appreciate that

Thanks!!

Thanks! I appreciate it

Great! I’m glad :)

Thanks!!

Thanks!

Thanks!

Check the next video, I coded it up and you can follow along and see for yourself :)

Thanks for the support! I’m glad you enjoyed it :)

Thanks!!

Thanks!

Calling yourself as a nerd is a good way to distort your perception of reality

​@@user-cg3sl8zu5cit's not that serious bro jfc

Parts 2 and 3 are up on the channel, they’re in a playlist together. Second video is called “I coded a real quantum computer”

Thanks for the tips! I appreciate it :) Honestly, this is one of my best performing videos by far - so I’m really happy with the view count lol. That said, I’ll look into optimizing titles and thumbnails, its hard to say whether the 3b1b style thumbnails would work for my content, but I may give it a shot.

Thanks!!

Thanks for the comment! The hadamard gate maps the state 0 -> (0 + 1)/rt2 and 1-> (0-1)/rt2, since we started on the second line with a 1 state we pick up a - instead of a + Edit: yes it has to do with the Bloch sphere. The H gate is a 90 degree rotation, so if you rotate 0 by 90deg you get +, if you rotate 1 by 90 you get -

Great! I’m glad :)

Hey - yeah I’m a huge fan of his work too. I emailed him and checked to see whether it was alright whether I used a short clip. The clips are in the description I forgot to link the videos though - so I should add those.

@Lukas-Lab oh cool! Its just nice to see some appreciation for that legendary individual. Respect to you bro

Actually that’s probably a good point - I like this description better.

@@Lukas-Lab Thanks for the response! Eh, I feel like it's fine to call circuit notation "machine code" most of the time, once you move to like measurement based quantum computers though, that notation just kind of fails to be a real primitive. Definitely fine for an intro video, I'm just being unnecessarily picky. Either way, I love to see people spreading the word about quantum computers, I really appreciate you making this series!

Thanks! Yeah - I’m gonna pick back up with the uploads. Had a long break over the fall since I was busy taking classes, but now that my classes are less intense I should be back to posting more frequently :)

It depends on the level you’re looking for. Nielsen and Chuang is a great textbook on the topic, there’s also a lot of good review papers that go over things in more depth. If you join my discord server I am compiling a list of different sources over there in a Google doc that I’ve shared

Thanks for the support :)

Will do! The next vid will be a more detailed walk through coding this up. Then after that I’ll probably do a video on shors algorithm.

Quantum internet is still in its infancy, I know a bit about it and I’ll probably make a video on it in the future. What do you mean by quantum intelligence? Do you mean using quantum computers for AI/ML?

This is a great suggestion! Absolutely I’ll do that.
