Quantum computing explained in 10 minutes | Shohini Ghose

A quantum computer isn't just a more powerful version of the computers we use today; it's something else entirely, based on emerging scientific understanding — and more than a bit of uncertainty. Enter the quantum wonderland with TED Fellow Shohini Ghose and learn how this technology holds the potential to transform medicine, create unbreakable encryption and even teleport information.

45 Comments on Quantum computing explained in 10 minutes | Shohini Ghose

    • I’d like to know ur definition of ‘erroneous’ results/output … Or rather let’s simply say That’s quite a huge risk to take! So y r the dummies like woohoo let’s go full blast on this?

    • +Shemi Rama She said it herself in the presentation; and Quantum computer can’t predicate future, it uses uncertainties to cheat. Math of probability doesn’t change with a different computer.

    • Let’s see if she can pull this off. –Nope. She doesn’t even properly define “flip” at 0:44. Does it mean, ‘turn the coin over,’ or does it mean, ‘generate a random heads or tails result’? –When the first thing out of your mouth is confusion, you’ve bungled badly.

    • Congrats to you both for delving deeper in your questions and statements. I mean that honestly and sincerely. Quatum Physics is like Kaos Theory (to me anyway)… The more you realize how limited everyones understanding is the more on the right path of thought flow we actually are. You do not need to understand everything to begin anything, we just need the tools and desire our brain already holds.

  1. The computer won by cheating, because after it’s first “flip or no flip” it did neither, it claimed it was in some “partial heads partial tails state”. That’s cheating.

  2. 7:50 She’s wrong about Quantum entanglement. No useful information is transmitted via entanglement. The laws of physics *literally* prohibits data being transferred faster than the speed of light.

  3. To sum up:
    “It’s very complicated.”
    “It’s so complicated that we can’t actually explain it other than stating that it’s non binary”
    “It’s so complicated that it can change the way the world works”
    “If you don’t get it, you’re beginning to understand it”

    • Its a scam. This “Quantum Computing” is a $$$Grant siphon that has been around for decades. They use the same talking points and simplified tech analogies as talking points to fool the unscientific liberal class and their journalists. I’ve never seen them offer a publication on machine coding for controlling the quantum state inputs and outputs. They show up about every 3 to four years to appeal to new audiences once the old ones forget.

  4. They didn’t even talk about what this means for specialized mathematics and storage capacities. A classical bit(Binary Digit, [0, 1]) is an characterized by a O(n^2), while a qubit(Quantum Bit) is characterized by a O(2^n). This makes seemingly enormous problems somewhat more manageable. For example: Say a classical computer the size of earth would have about the same computing power as quantum computer the size of an elephant(theoretically).

    They fundamentally work differently, so don’t expect quantum computers to make your phone or laptop any faster, but for the scientific community that need solutions to extremely large data-set problems, or fundamentally complex can now be rapidly calculated.

  5. Let’s see if you can pull this off. –Nope. You don’t even properly define “flip” at 0:44. Does it mean, ‘turn the coin over,’ or does it mean, ‘generate a random heads or tails result’?
    –Truly horrible. She rattles on about the game, then wanders into ‘why quantum computers are good,’ then wanders back to the original game metaphor…

  6. “If you are confused by quantum, don’t worry. You are getting it.” Wow, that’s a really sly way of pretending you’re explaining something when you aren’t at all.
