The Map of Quantum Computing - Quantum Computing Explained

[@exxzxxe]

A short 'war story': I spent 17 years in supercomputer field (Cray Research, Thinking Machines, etc.). In 1992 I completed a project to mathematically construct the first N elements in the periodic table from first principles (using Feynman-Kac integrals while accounting for spin). I used the 65,000 CPU Connection Machine (27 Gflops, $18 million). I was able to compute the ground energy state atomic structure up through boron (N = 5), within 16 hours. Today, researchers may be able to reach N = 30. It is clear the only way we will be able to simulate molecular biology is with quantum computers!

[@stretch8390]

Great story thanks for sharing! What did you write it all in if I may ask? Fascinating history. Would you tell us more of some of the challenges you faced?

[@tomc.5704]

I am so excited to see what quantum computing will do for the fields of molecular chemistry and protein engineering We're already making breakthroughs with classical computers and have incredible potential with neural networks....but if we could use a quantum computer to model the system? Just program the energy function and get out the lowest energy state solutions? That would be the silver bullet. The golden ticket to understanding all of biology, even the entirety of cells at the atomic level.

One of the best videos about quantum computing I've seen yet. I'm getting my MS studying quantum computing, focusing on the software side, and there are few good resources on or offline explaining quantum computing and it's advantages and disadvantages to a general audience.

[@JNCressey]

Do you know any good resources to learn how to start thinking on how to design quantum algorithms?

[@georgegrattan7319]

The language of quantum is linear algebra so I’d start there if you don’t already know a bit of it. You can then go on to learn about quantum states, and operators on those states like the Pauli matrices and different operators composed of the Pauli matrices like the Hadamard gate. Then I’d say start with Deutsch’s Algorithm and Grovers algorithm. Quskit and IBM actually have awesome resources for learning all this, and IBM’s circuit composer is super cool to play around with too. If you aren’t too interested in the physics of it all the textbook Quantum Computing for computer scientists is pretty good, although it skips over a lot of the physics that, until better error corrected computers are available, is really valuable to know.

[@JNCressey]

@@georgegrattan7319thanks. I guess I'll look up Grovers algorithm and continue watching the rest of the Qiskit youtube series. I have watched some of it before, but I sort of burned out from the feeling of knowing how to follow the quantum circuits and calculate how the state changes, but being frustrated at having no idea how to design an algorithm for it to calculating something.

[@stretch8390]

How does the software side of the field look? Is it going to be monopolised or are there a fair few competing developing softwares?

[@georgegrattan7319]

@@stretch8390 Right now, at least to my knowledge. The software side is largely sill theoretical, since we don't have an error corrected, many qubit computers to run the software on. Looking around for internships or jobs on the software side largely put you in a large tech firm like Google, Microsoft, or IBM but there are tons of startups that I believe that once the hardware tech is better, will need quantum software skills.

[@alvinwu8509]

Just recently read a book about chaos theory and it talked about weather forecasting - specifically, how difficult it is to accurately predict the weather beyond a few days. This boils down to how complex systems such as weather are self referential and as such even the smallest changes in one of its parameters will eventually lead to a massive change down the line. We are talking about how even a millionth decimal place in the speed of wind could eventually lead to massive changes down the line and this change is not linear in fashion. I think that's where quantum computers could be quite useful as we can model the entire ranges of a parameter using qubits rather than trying millions of combinations for a slight change in just one parameter.

[@immko]

@@noisemagician I don't know you so I'm just guessing, but if you've enjoyed teaching for a longer time then you probably have been trying to get better at it for most of your life, at least after you discovered liking it. Topics DoS teach are complicated things to learn, but not necessarily so hard to describe after you familiarize with them enough, also considering he seems to enjoy teaching so he probably have done it for a long time and if he wanted to honestly improve in that then he have done it quite effectively for several years. You get really good at anything if you train effectively for several years. Also because we can't be completely sure if there is such thing as "natural talent" or "gift" I think it's more beneficial to believe you can learn everything you put your mind into instead of handicapping yourself by believing you might not have gift for something.

[@noisemagician]

​@@immko I enjoy doing it it's not my job or anything but I am good at certain things and I enjoy teaching other people what I have learned and enjoy doing. I makes me happy to see them ''get it''. I might have gotten better at it over the years by practicing. I somewhat agree with you, I think that a lot of things can be thought and learned, with practice even perfected. But there is a limit to that, a simple example would be Francis Nganou, the current UFC heavy weight champion. He has been training for ONLY 5 years, he has what they call ''the touch of death''. If he connects he will knock you out. Power punching is one of those things you can''t teach. Any person can learn to punch harder but no matter how hard and how long you train you will never be able to generate as much power as him. I think the same applies to mental feats as well. You can get better at mathematics and physics but no matter how much you practice you will never be as creative and smart as Einstein or Newton. We can always improve but we are limited by our genes and the environment that molded the expression of those genes.

[@immko]

@@noisemagician That's where our opinions seems to differ. On Francis I agree completely, it comes from genes and if you don't have them there is nothing we can do, at least before crispr gets better or something similar. I do disagree on the mental side of it, I really believe nobody is born with 200 IQ, they have to learn it. Information is only patterns and if you train your pattern recognition and creativity you can understand anything that our brains can comprehend. There are some limitations that science seems to have discovered, for example some people can at a glance memorize 3 things where others can go up to 5 or even 6 in very rare cases, but it's not clear how it helps or if there is downsides on other areas. Learning mental capabilities are still not easy and 'gift' could be described as "started very early in life and had enough luck to do it effectively" which would result in many years of effective training without knowing its training.

As for a newbie, there are a bunch of things where the visualization can actually give a wrong intuition and WTF impression. So good visualization is important not necessarily to show what actually happens, but to provide at least some intuition as to what results are going to happen or (probably) won't going to happen in some common experiments. Even better if it can state what intuition we can leave in place and don't need to be prepared to alter: e.g. euclidian 3 space +1 time dimension. - Qubits, which are both 0 and 1 at the same time. Having an "arrow" inside qubit makes an impression that some internal state definitely exists, like if we had an arrow pin-pointed to the center but then it is covered with a piece of paper. So even if we don't know the state, the state actually exists and won't change if we do the experiment later or sooner. Isn't it better to represent it with some artificial or real-life system? Not sure what though. Maybe, some probabilistic fog around the "center of particle". - Can particles still be represented as something having a "center" in our space and can I still think about space as 3D+1Time? General relative is already making this intuition weak. - What does it mean for 2 (or more) particles to be entangled? E.g. even when entangled particles are distant if we change one particle, another one changes as well. Is it or there is a common other interpretation? - Measurement is a strange one. In macroworld, measurement doesn't change the measured object. If this is not the case in QM we should have chosen another word for the process, e.g. action or interaction. And thanks for Qiskit! This one seems to be really useful.

I think your next video on the current research efforts and their progress so far will be very interesting. A good benchmark would be the size of the integer they can factor. Wikipedia lists results but some of them look quite suspect. From the results listed, it seems that you cannot just put in a number and get out its factors. (I imagine that not everyone is working on factorization, but a lot seem to be.)

The best way to look at and understand quantum computing to date- in my opinion! Love this video. Thanks!

1:03 Quantum Computers are not in a huge number of states at the same time, they are in one state, the vector of the wavefunction.

[@kevin42]

These then get "translated" to the basis vector components (uppon wave function collapse) which we call "classical" states. Its also worth mentioning that the classical state basis components arent classical at all and are also uncertain according to the uncertainty principle. The classical states we call "normal" reality are just an infenetesimally tiny fraction of all the available states. The uncertainty principle isnt weird, our states are.

@@kevin42 the computational basis is just one choice. My point meant to say, that this claim leads to misrepresentarions of qc of the form " qc work by trying all possibilities at once." A balls position is also a 3d vector, but we dont say that the ball is in 3 states at once.

[@Ntropic]

@@kevin42 there's no uncertainty between the computational basis states. They form an orthogonal basis, non orthogonal basis states on the other hand are uncertain

[@kevin42]

@@Ntropic i didnt mention anything retarding "being in different states at once" for the soul purporse of not causing confusion.

A masterpiece of concision and clarity. Bravo!

Honestly, I have a degree in computer science but more than half of this video goes way above my head lmao. I have basic knowledge in quantum physics and have looked into quantum computation but it's all really confusing af.

Great video. I don't think the explanation could be clearer. I like how it also shows how we 'think' something works and since we as humans, can't leave anything alone until we've broken it, accept probability as the answer. But probability isn't certainty. If it were, breakthrough discoveries would never need retracting.

Thank you for another excellent video, makes me feel excited about the future!

[@DaleStubitsch]

Amazing video! Thanks for taking the time to make it. Have recently become aware of companies such as D-WAVE and IONQ. A couple of questions, if you will: 1) Is there an ideal “best” or “best for now” method of quantum computing (annealing, adiabatic, etc)? 2) Is it inevitable that annealing will evolve to adiabatic? 3) Is the adiabatic approach "best" or just a different way of accomplishing this? 4) How long do you think it would take to make an error free 1,000,000 qbit computer? 5) How long do you think it will take until quantum computers can be used for ‘every day’ application? Many thanks in advance! Keep up the good work!

"I'll be referring to as classical computers". Next sentence: "...normal computers..." :D

[@Reptex_cs]

All the videos I've watched on QC barely gives a hint at how it works. This one however, hits the spot. Thank you!

[@kyrianrahimatulla1561]

I think the weather forecasting thing is related to fluid simulation, which is computationally intensive for a classical computer (assuming you want an accurate simulation), but supposedly much less so for a quantum computer.

[@stormcrow1685]

This is an incredibly well put together video, between the hierarchical approach to the topics and the easy to understand visuals. I've read about quantum computing a couple times prior to watching this video, but the sphere visualization made things so much clearer for me, coupled with your amazing educational skills.

Thank you for making a distinction between adiabatic quantum computing and quantum annealing. I've always conflated the two, or haven't quite known for sure if they're different things. I'm now motivated to dig deeper to learn more about the distinction (recognizing that you can't get too deep into the weeds on that point, since this is an overview video)

[@pdelong42]

Also, I hadn't realized that the circuit and adiabatic formulations were equivalent. More homework for me to assign to myself... :-)
