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.

  1. Casinos in Las Vegas surely do not have quantum computers but their quests have quantum wallets.

  2. I don"t believe that flipping a coin state of in "nature life" the computer can predict a 97% success rate , its just not true ,. these probability are predicted within a software enviroment based on human behaviour patterns. If it can you've discovered a profit… However Quantum computers will control and eventually rid the environment of man , he will become redundant..

  3. OK so it's sounds like . that Will always have super position.. that overall inscriptions .. OK it can be very useful but have to understand more . . 🤔 its exciting 👏👏

  4. Thank you for all this, now I know what are possibilities of this field 🙂

  5. I JUST PRINTED AN ARTICLE SO I COULD MEMORIZE GRAPHINE & SILICON NITRIDE. IT DOESN'T EASILY ROLL OFF THE TONGUE. I HAD IT MEMORIZED & THREE MONTHS BATTLING CON ARTISTS ON THE INTERNET I FORGOT. THE PAGE PRINTED SO SMALL I WOULD NEED A MAGNIFYING GLASS TO READ IT. SO MANY HTML5 PAGES DON'T PRINT CORRECTLY OR SAVE TO PDF CORRECTLY. INSTACART SCAM ARTISTS I'M TALKING TO YOU. THESE KIDS CAN'T MASTER HTML5 HOW WILL WE EVER ARRIVE AT QUANTUM COMPUTING BEFORE A FULL SCALE WAR OR PLAGUE ACTUALLY BREAKS OUT??? This is exactly why I STOPPED INVESTING IN TECHNOLOGY. I SENSED A PLATEAU.

  6. It's like humans are learning the language of aliens

  7. For now, there is no science fiction again!!

  8. … and will human beings ever have quantum spectrographic ultralaser machines, faster pantographs/3D copiers/3D printers, quantum cell phones 📱📱or this has nothing to do with what the scientist has explained and it is a silly question? 20210905 (Sunday).

  9. Normal computers have transistors.
    Quantum computers have electromagnetic manipulated electrons spinning in a circle.

    How they turn either of those things into useful programs is beyond me.

  10. Is it just me are does this feel like bull** . The computer doesn't follow the same rulles! So it is cheating. Schrödinger's cat explains why, as long as we don't look the quantum state is there. But once we look it is gone. If we flip 1 to 0 but don't tell it still is 1. If the computer flips it is 0 but could be 1. If we can not look and don't know if it was 1 or 0 it can still be 1 or 0 . But nothing ells ! The bigger problem is with data. If it can be 1 or 0 at the same time there has to be 2 instanses. As for test results they would never be the same. Since all data exists in multiple states at the same time. if for example I enter a 1 it has a calculation but if has all states the outcome is not predictable so not useble.

  11. How to say everything and yet nothing. What a quantum explanation!

  12. Well, I guess I'm now a QUANTUM COMPUTER!!

  13. It’s cheating… let me know when it can beat a roulette wheel and I’ll be impressed.

  14. with the slider volume (like 5v = 8bit) and motor to move this volume so 10 volumes will store 8bits * 10 (in combination) so to store FFFFFF we put 1st to 9th on 0v and 10th on 5v so to read we calculate voltage of each volume.

  15. Your everyday pc: yes or no

    Quantum computer: maaaaaybe….

  16. she says nothing this was a lecture with a overused TED tone voice that says nothing.

  17. ‘If you’re confused don’t worry you’re getting it’ is really an underrated joke herr

  18. Great in the showcase but crap in the stockroom.

  19. It knows all your non-quantum passwords because it unmixes them into one single password.

  20. nope. there is a chance that one guy in this room is not right. and it s propeply not me.

  21. isnt this what Mary Vaughn was doing in hidden figures when she was calculating the US space program, she was called a computer she was looking outside of 0 and 1s somewhat

  22. It’s a good beginning … look forward to lot more.

  23. I don't get how the computer won. I don't really get the game. Can anybody explain this?

  24. 06:50

    This speaker used Alzheimer as an example of needed medicine for human being.
    This disease kill thousands in west, but Malaria kill millions in Africa and other poor countries.

    She is thinking about the rich health not about poor health, even if they are more.! And that is how those people mind.

  25. Hoy en día ya tenemos internet quantico, se implementó en un par de edificios de investigación

  26. This seems like a cool technology, but it scares the crap out of me.

  27. Isn't the computer just 'cheating' or have I missed the point?

  28. So maybe time travel is possible too? isn't it?

  29. Thank you. Now I simultaneously understand and don't understand quantum computing.

  30. Is basically saying that if one decided Schrodinger's cat was dead, the quantum computer could mantain it alive.

  31. Bio hacking at a whole new level is what quantum computing is with your brain. Since they can now produce medicine through water signals, and with 90% of your brain is water that’s scary. Reconsider donating your DNA at these covid tests/aka dna harvesting parties
