The Map of Quantum Computing - Quantum Computing Explained

With this video I aim to give a really good overview of the field of quantum computing with a clear explanation of how they work, why people are excited about quantum algorithms and their value, the potential applications of quantum computers including quantum simulation, artificial intelligence and more, and the different models and physical implementations people are using to build quantum computers like superconducting devices, quantum dots, trapped ions, photons or neutral atoms, and the challenges they face.

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!

Hello everybody, thanks so much for all your really nice comments! A lot of you have said that this is the best introductory quantum computing video you have seen, which really puts a smile on my face. That's what I was aiming for so I put loads of work into it and I'm glad it paid off. Thanks for taking the time to write a comment, it means the world to me! All the best, Dom

I shed a few tears of relief ... this presentation has given me yet another sliding door moment. I love the illustration, pace and most notably; the objective approach. Not many content creators deliver with such transparency. Even fewer speak from a place of exposure. This is one of the few moments the algorithm has come through

Error correction and instability was a huge barrier in early classical computing too. Geniuses like Richard Hamming spent their entire careers developing error correction schemes to get these reliability problems under control.

[resonatingvoice]

This is by far literally the best video on quantum computing. You have explained this complex topic in such a simple manner, it not only helped me understand what they are but also enabled me to think about how I can use them to solve problems in my field. Thank you so much for your hard work.

[WestonMurdock]

Just finished taking a course in Quantum Computing at my university, and it was so cool to hear you explain all these topics and be able to follow along, while also hearing about some of the things we didn't cover in the course!

[BadRush]

This guy really makes it easier for me, since i learn faster when i have a high view over the subject. Nice work and i hope to see more!

[mkossen]

This is an incredibly informative and all encompassing work on introduction to quantum computing. I just wanna say, the YouTube algorithm should suggest this video to each and every one of the users who have ever searched for phrases like 'quantum computer' or 'quantum computing'.

[stachowi]

wow, as someone who's always wanted to know how this worked (i've watched other things about QC), you really have a gift for teaching.

[hellodavidryan]

A quick note to say congratulations on such a lovely video. I'm part of the product team at Quantum Brilliance, building room-temp quantum computers via diamond NV technology, and I'm always looking for great examples to share with people coming into the industry. I really appreciate the nuance you unpack here too, and I think that's something that's going to be particularly useful, especially for those coming from FAANG roles who are curious how to get comfortable with the fundamentals even as they join and focus on their areas of business. Great work mate.

"You don't need to subscribe or anything..." - Subscribed my friend, one of the best videos of quantum computing on YT.

[dexterdextrow]

The pedagogical quality of this video is absolutely astonishing. It's superb in terms of clarity, plenty of examples of applications for reference, good analogies and incredibly accessible as an introduction.

I swear to God, your shoutout to Qiskit was the only add on YouTube ever that I enjoyed watching. Also amazing topic and thank you for helping me to write my Quantum CS homework. I really love this channel.

[orestlenczyk]

this is the greatest video i have ever seen. I can not express my appreciation more. Even the sponsorship part - never been so engaged in an ad. thank you!

[GrischaEkart]

Small blunder at 9:08: "Is it twice as hard or even exponentially harder?" If you add a digit and the problem gets twice as hard (repeatedly), you have an exponential problem.

[radoslawbiernacki]

I just found this pure gold. This is probably the best video of 2021. Your skill for clear and direct explanation and also systematic approach to the topic is inspirational for me. Also great graphics!

[johnbarbuto]

Real science and real scientists are such a joy. They make the world a better place (at many levels) by looking for truth and being truthful about looking for it. Thank you for this video!!

[russiankid]

You had my curiosity, but now you’ve got my attention!
It’s been a while since I’ve been this stoked about learning and progress, thank you for such clear and articulate explanations. I love that you’ve thrown in terms outside the scope for those want to dig deeper.
I’m about to study the shit out of this!

[irezak]

You are so unbelievably clear, its astounding. You've turned a week-long paper-reading rollercoaster into a 2-day endeavour. Thank you very much.

[itetecnun]

Man! This is by FAR the best explanation of quantum computers I've been able to find so far. Thank you very much for the astonishing amount of work and research there's behind it. Really good work!
