Quantum Computers Explained in a Way Anyone Can Understand

Everything I've seen trying to answer what quantum computers are or how quantum computers work seems to always give me abstract answers and just leaves me with more questions. So in this Decodr episode, I bugged the hell out of some quantum scientists and think I can give you a better understanding of what quantum computing is, how it works, and what it will help us with (and what it won't).

Thanks to NTT Research for sponsoring this video (& letting me bother their scientists). Check out what they're doing in the world of quantum here - unlockr.co/NTTResearchQuantum

    Thanks again to NTT Research for sponsoring this video! You can join them virtually for their Upgrade 2021 event where they'll even be demoing a CIM: unlockr.co/NTTUpgrade2021
  • What a great overall look at Quantum principles' basic theory plus applications. I enjoyed this BIG PICTURE vid a lot. I grew up with Particle physics and quantum mechanics was just coming onto the scene when I got older. Nice to have some of my information confirmed about Quantum mechanics and to have simple ways to THINK about it all. Our world is indeed changing quickly, and keeping up is as much about the details as it is about the big picture. Thanks for the Big Picture, David!
  • I am a programmer of android apps , and I still do not get it properly, this video of yours is farr from explaining to everyone
  • First video ive seen of yours, but not the first video on quantum mechanics or quantum computers. Im a computer engineer and I love this video, especially the cuts of just cityscape. You give a small amount of time to reflect what is gonna be explained. Genius! And the video has a feel like that of walking and talking with an old friend 😄
  • @tmcmat01
    This was a great starter for me. I've been trying to figure it out on my own, but I'm not a math or science guy and I'm just old. LOL. I'm gonna watch it a couple more times. My original programming effort literally involved wiring punch boards... yes, before punch cards... and building a Radio Shack computer. I want to see what the hardware looks like vs a "regular" computer, i.e. the chips, etc.

    This is the first video of yours I've watched and it was epic. I've see a lot of articles on quantum computing lately but science is a hobby and not my day job, so it was great to find a video that could lay this out in a way that was easy to grasp.
  • @dannydav709
    This is such an amazing intro. So thorough and easy to understand. You earned another subscriber!
  • @warpoet90
    This cleared up a couple things, but I'm still confused about a lot. I'm particularly interested in the actual physical mechanisms that are taking place. How exactly are the electrons being set in place and measured? What is actually physically happening to make calculations?
  • @MUSTAFA-fe8ql
    Very useful, we need another video about the other uses of Quantum Computer in decoding , cyber security , its expected effect in cryptology and crypto currencies besides medical , pharmaceutical and physical uses. Thanks 🙏.
  • I like the way this guy teaches. Ive heard of the concept of "quantum tunneling" my whole life and can now easily explain it to someone. The ball bouncing off the wall example helped a lot.
  • @TimOfKenya
    very interesting video. great use of a videographer, and hope to see more mixtures of vlog style, as well as 3rd person shots.
  • @jserien08
    Congratulations, you have provided the first light of understanding on this topic to me! 👍
  • @Davey_Cakes
    When it comes to quantum computing, I really like the "traveling salesman." Another good visualization is a person making their way through a maze, where all the potential paths are calculated at once to find the perfect path. Such a cool idea.
  • @nerovanguard846
    Dude, I barely understood anything you said but I still loved it! I love everything about the video and that thumbnail is gold!
  • Love it subbed!!! I've been trying to explain this to so many people but all I can do is absorb knowledge I can't explain jack. Thank you I'm saving this vid! Now my explanation will simply be a link click 😁
  • Terrific Job, simplifying where you can to get the main issues across. Electrons don’t really spin, but they do have magnetic moments of inertia as if they did :—)😊
  • Beautiful and cogent explanation for the quantum computer. Best explainer I've yet come across... Good job!!!
  • @curtisowens750
    That was very well explained. I have seen a lot of programs that explain how they work but never real practical applications.....I commend you on adding that portion....The why should I care piece....Good work!
  • @gaewchiangmai
    I subscribed to your channel after watching this video about Quantum Computer. At the moment, this is the most understandable video so far. The videos about Quantum Computer out there are either not related or relevant to me, or I am not smart enough to understand them, Thank you for your work! Keep producing videos like this one!
