Quantum Computing with Light: The Breakthrough?

Ma’am, I have learned more about physics by watching your channel than all my school years could ever provide. I just wanted to say a vey big thank you. Peter U.K.

0:21: 🔬 Quantum computing has made significant advancements since 2021, with the ability to calculate using entangled qubits for certain mathematical problems. 3:34: 🔬 Quantum advantage and utility are demonstrated through fast calculations and random distributions using quantum processors. 6:57: 🔬 The challenge for photonic quantum computing is to have reliable sources for single photons and to shrink down all the elements onto chips. 10:32: ! Atoms in tweezers are a variation of ion traps, but using neutral atoms instead of charged ions allows for more scalable 3-dimensional configurations. 14:14: 🔬 Multiple companies, including Microsoft and Google, are making progress in topological quantum computing, which could lead to easier scaling of quantum computers.

This was brilliant, thank you. I feel that I can trust the thoroughness of the research done and that you will talk about tradeoffs and not get swept up the hype of one technology.

Make your new knowledge stick! This video comes with a quiz: quizwithit.com/start_thequiz/1696490804059x6515197…

Thank you, Sabine! Love your method of presenting the complex things.

You said "ions are atoms that are missing some electrons, so they're negatively charged." Wouldn't they be positively charged?

Thanks for the update. I was curious what happened in the quantum computing hype bubble. :)

Thank you Sabine. At 10:36 you mention that "ions are atoms that are missing some electrons so they are negatively charged". However, if one removes negatively charged electrons from neutral atoms, the resulting ions would be positively charged right?

Thank you on behalf of a lay person curious about what's the next step in computing and all things exacting. You keep it real. Please keep up your interesting and current content.

Thank you for the video.

300 years from now a student is going to build a lego quantum computer as a "show and tell" experiment just to spite that famous Nobel prize winner Sabine Hossenfelder.😊

Thanks a bunch for the video and all the info, Sabine! 😊 Stay safe there with your family! 🖖😊

Great summary! Would have loved your take on DWave's approach using quantum annealing!

Thanks, it is a great and comprehensive review of QC !

Thank you for all your research Sabine. Great video! ^^

I always like and comment because you are terrific and seldom mention that I should like and subscribe (I am) and whenever you do, you do it with grace and intelligence. Love that you treat us like we are not morons even if compared to you we are lacking. Thank you for being brilliant and yet taking the time to explain things to laypeople. You are my Feynman.

I love how it went from Quantum Supremacy -> Quantum Advantage -> Quantum Utility

Well done Sabine! It will be interesting to see which company comes up with the best Quantum Computing technological innovations going forward. I am certain that you will keep us well informed!

Thank you Sabine!

I LOVE your videos. They straight forward SCIENTIFIC FACTS with no BS or BIAS, mixed with some really hilarious subtle humor. Thank you so much, keep up the GREAT work 😁 SUBD 😉
