Wow this is a great connection! I really enjoyed your video! Ive been watching your videos frequently since you covered Korean CSAT exam last year! Keep up the good work Tibees!

That was actually the first time I kind of get my head around Quantum computers programming. But I think we need more complicated examples solved on paper first before being coded so that we get the idea more deeply.

This was a very fascinating subject for you to cover. I had no idea there already were some basic quantum computers out there and that some have been made available for anyone to use. I really enjoyed this presentation. Thank you Toby! Absolutely love your channel!

Though I love all of your videos, it has been such a wonderful journey seeing the quality of your videos evolve over the years so much!

Your videos are fascinating and informing. Will look forward to your future videos, Dr. Tibees.

Nice video. Thank you, Tibees. I still don't understand how one goes about picking which gates to use! I hope you'll make more videos to help us understand how Quantum computing works and what kind of problems they can solve. You make things easier to understand.

Thank you Tibees for the background in Qiskit. I will look into it. Very informative. I always wanted to know more about quantum computing but this was the first explanation I could understand.

Really excellent explanation, this is the first time I’ve seen quantum logic functions explained, and you did a great job!

I love your presentation method. It actually makes sense. I see this for practical purposes such as the likelihood of a lightening strike and a resulting forest fire, and where it will strike.

Excellent! You do amazing work!

This video is fantastic. I really liked your explanation of quantum computing. More please!

I like you are using this old projector!!! remind me so much memory!! merci :)

That’s a great video! Thanks Toby

Quite an interesting concept i have learned today. Thank you tibees. 😁

Fantastic. Thank you for sharing this.

This video reached me 1y later but is still strangely applicable with the New Year’s resolution suggestion. I’m a Computer Science major minoring in Physics and haven’t had much experience with quantum computing other than readings so this is all new to me. Thank you for sharing.

Still some of the best/most wholesome educational content on the platform! Thanks.

Great video! Thank you so much!

Hello Ma’am, I recently stumbled upon your channel, and it is quite interesting (coming from someone who hated math back in the days), I sincerely thank you for helping me reconsider my relationship with maths😃🤝

I have watched probably over 5 hours on quantum computing material; I have looked up videos and websites, but you are the first one to explain the quantum logic gates. In fact this is the first time I have even heard them mentioned in a quantum computing video. So I would just like to thank you for not just saying "A qubit can be a zero and a one at the SAME time. So yeah that's all you need to know". Okay, sorry for ranting, its just irritated me a lot, and thank you again for explaining it so well. (Your description of where it comes from too, has made a lot more sense then just about all the other videos, but I digress). Thank you so much for this wonderful video; I appreciate it; and thank you so, so much for explaining everything so well. It must have been painful to figure all this out yourself, I can only imagine the amount of time you spent looking at webpages, forums and scholarly articles, "summaries" and studies. (Looking back this sounds a lot more condescending then I planned it to, my point is thank you so much for what you have done.)

Outstanding presentation!

Thanks! I’m going to try this out! Although, I still do not understand quantum computing well enough.

This is the easiest video explaining qubits, particularly the spherical representation seems very simple.

Never seen such a good explanation of qbits, this really drove the idea home for me! Though I wonder what actual application there is to having the H gate, apart from randomizing and un-randomizing a value - this sure feels pretty unique, but I am not sure in what case this is actually beneficial. Having a hard time thinking of real-life scenarios where this could be a valuable asset

Best video explaining Quantum Computing ever!

This is the best video explaining quantum computing.

First Quantum Computer video ever to show how it works. All the other science people just describe the features of a quantum computer . But showing a real calculation with variables would have been better. The best part of your video is that you give useful sources where the people build and run them. I can go and learn myself. Side note I learned Basic programming language on a paper punch tape teletype machine connected to a computer 9 miles away. That was pretty high tech back then.

I'm pretty sure this is the first time I've seen an overhead projector used on KZread, which blows my mind a little bit.

Thanks for explaining quantum gates

Thanks!

5:13 But once you measure it pointing in one direction, every subsequent measurement will show it pointing in that same direction. So you have not actually determined that it was pointing to the side, only that it was pointing either up or down.

Thanks a lot.

Pl make further such videos on other gates and multiple qubits system. 👍👍

That is amazing! Great video as always! I was reading up on quantum computing just yesterday, and this video popped into my feed. DIdn't know that IBM offered free quantum computing resources...

Imagine being sponsored by IBM. So cool!

My greetings I am an inventor and I am passionate about mathematics and physics and this has helped me in many inventions and I am working on a quantum computer and I have reached a good stage in this subject ( and your videos are very interesting )

Interesting what you do with your overhead projector.

Based on what you submitted, if you ran 5 shots, would they all run at once or would the same qbit just reset and do all 5 runs?

0:52 yea that can't be coincidence

So if I just watch this video every day it's always a bones day? Who knew you had the cure for depression!

Can you explain why it takes 2 minutes to run a single shot? Is that due to the cue or is there another process taking place here increasing time complexity?

Quantum comp and nuclear fusion tech are the two problem I want to see getting solved before I retire.

Great explanation. Ty. :) Do you think superposition is really a superstate... or... if we think of the sphere being half 0 and half 1 and either pole being a point, the rotation on two axes put those points on the boundary between the half that is 1 and the half that is 0... could it just be that there's some natural wobble across this boundary line and it's more about our measurement precision and timing that explains the approximate 50% 1 and 0 measurements?

Propably the qbit in superposition changes its state so rapidly and unpredictably so that it can be treated as if it were a superstate, Allthough I think it has a state all the time and not only when we measure it, but I honestly dont know

You can measure it along a different axis, and if you measure it along the axis fitting it’s current state, you will always get the same thing. It isn’t like when it is in a superposition of 0 and 1, that that is fundamentally different, as if some states “are superpositions” and some aren’t. It is some are superposition *of 0 and 1* and 0 and 1 are just entirely 0 or entirely 1, but you can alternatively describe the 0 and 1 states as superpositions of some other states (e.g. + and - ). If you measure the 0 state in the 0 1 basis, you always get 0, but if you measure it in the +,- basis, you get + half the time and - the other half of the time. While, if you have it in the + state, and you measure it in the 0,1 state, you get 0 half the time and 1 half the time, but if you measure it in the +,- basis, you always get + . And, the 0,1 basis and the +,- basis are both just two bases from a continuous family of possible bases (if you pick some basis at random, and prepare a bunch of states as the first state of that basis, and measure them in some other basis, the proportion of measurements that you get in one of the options or the other, depends, basically, on the angle between the two bases.)

@@drdca8263 by "measure the 0 state" do you mean measure a 0 state control qubit?... Or measure a qubit in superposition and have it collapse to 0? ... Or perform another H gate operation, which rotates my proposed boundary position back to starting point (clearly 0 and no longer subject to measurement wobble that might give 0 or might give 1)? I don't think it matters whether you're talking about spin or charge, the action of the H gate is the same - rotating from a clear 0 or 1 to a hyperspace where there's a boundary between the two. Whatever you're measuring (spin/charge) would have the same grey areas boundary line with ~50% measurements one side and ~50% measurements the other. But we only have repeat experimentation to go on.. we can't even test the same qubit twice.

If the first H gate turns the arrow in one direction to be in the middle then why did the second gate turn it back to 0 instead of keeping the same direction and going all the way down to 1?

@vk2ig

Because it rotates the arrow by 180 degrees around the line between the X and Z axes. So one rotation takes the state from one state to the middle or superposition state, and then the other rotation takes that arrow back to the previous state.

Thanks, for an interesting (as always) and fresh introduction. Could you proceed to the topics beyond mere a random number generator? As a side note, it is interesting to compare this with ternary, four-state, fuzzy and probabilistic logics, some are almost a century old. E.g. the H gate applied to 0 or 1 is a direct equivalent of fuzzification and reading the Qbit is of defuzzification. Ternary logic can handle uncertainty, so does the superposition. Four-state logic can also handle contradictions. Is it possible to express contradictory inputs in a quantum computer and pass these through the gates, i.e. do logical inference from? Three axis should be enough, or?

I invented a method to turn any ring into a logic. So binary, ternary, e.g, Which means this method can actually also generate complex logic, infinite logic (a logic with infinite truth values), uncountable logic (a logic with uncountably infinite logic values), 0 logic, 1 logic, probabilistic and fuzzy logic, with this method a concept of equivalence of logics also becomes obvious with that a measure and so 'sublogics' - a logic contained within another logic, so it turns out that probabilistic logic is a 'sublogic' of fuzzy logic, which is a 'sublogic' of uncountable logic, which is a sublogic of complex logic. Cool stuff. I was going to write a paper on it a few years ago but got distracted due to covid and other stuff.
