I think I'm too old to get my head around quantum computing. Every time I think I've observed what it actually is my brain collapses into a state of needing a drink!

[perrymcclusky]

I find the research and development of quantum computers fascinating. It is a similar fascination that I had in personal computers back in the early 1980’s. I always look forward to these annual updates. Looking forward to your next video!

[esra_erimez]

Quantum Computing solves the hardest problem in the world. When you put a sock on your left foot, the other sock of the pair instantly becomes the right sock no matter where it is located in the universe.

[reghunt]

I was recently thinking I need to revisit Quantum Computing, and see what's been going on these days, and naturally remembering your earlier videos. Then this pops up. Thanks.

[KTHKUHNKK]

With everything I've seen over the last 50 plus years
I too am convinced this will come to be.
What an amazing time in world we live in.
Thanks Chris

[Praxibetel-Ix]

Looks like a bunch of interesting stuff is happening in the world of quantum computing. Thanks for this quantum update video! :)

[familyplans]

This is why i love this channel, i love to learn new things and as always its a well produced and edited piece

[dxutube]

It's that time of year again. Lots of very big words, the future is very exciting. Thanks for the update.

[lesliedeana]

Thank you for your continued work! Always done with such wonderful detail!

[Fran-hdft]

Imagine how we (humanity) would improve in quantum computing if all these companies and labs would work together sharing their knowledge.
Great video, very informative, as always.

[Colin_Ames]

I don't know as I'll ever fully understand quantum computing, but I certainly enjoyed watching this video for its clear and concise presentation of the subject matter.

[ArniesTech]

As always educative and entertaining. Thank you Chris! 🙏

[humayunbutt]

These videos remind me of early morning Open University science broadcasts from the 80s. Great work. Thank you.

[martinsmith]

Thanks for the edifying update Chris. I'm sure there were people who scoffed at ghe idea of a computer in your home, but it happened. The R&D budgets of these giants will produce something scalable to eventually reach the home market. You won't have to wait so long to render graphics. Perhaps in 30 years we'll get a RPi Quantum. Have fun

[dkgalbraith]

As always - thanks Chris! One of your recent videos with the 3D graphics of the motherboard and case was awesome 👌 a nice touch

[pidojaspdpaidipashdisao]

I haven't understood most of this video but I still enjoyed it

One way to think of quantum physics is that the wave particle duality of light and matter in the form of electrons is forming a blank canvas for us (atoms) to interact with; we have waves over a period of time and particles as an uncertain future unfolds. The mathematics of quantum mechanics represents the physics of time with classical physics represents processes over a ‘period of time’ as in Newton's differential equations. In this theory the mathematics of quantum mechanics represents geometry, the Planck Constant ħ=h/2π is linked to 2π circular geometry representing a two dimensional aspect of 4π spherical three-dimensional geometry. We have to square the wave function Ψ² representing the radius being squared r² because the process is relative to the two-dimensional spherical 4π surface. We then see 4π in Heisenberg’s Uncertainty Principle ∆×∆pᵪ≥h/4π representing our probabilistic temporal three dimensions life. The charge of the electron e² and the speed of light c² are both squared for the same geometrical reason. We have this concept because the electromagnetic force forms a continuous exchange of energy forming what we experience as time. The spontaneous absorption and emission of light photon ∆E=hf energy is forming potential photon energy into the kinetic energy of electrons. Kinetic Eₖ=½mv² energy is the energy of what is actually happening. An uncertain probabilistic future is continuously coming into existence with the exchange of photon energy.

When I was I kid, my grandparents heard I had an interest in electronics. They found an old "integrated circuit experimenters kit" and gave it to me. It appeared very outdated to me because I understood integrated circuits to be 74xx TTL logic chips, and had no interest in analog circuitry at the time. But it was very interesting just the same. The kit had a large (3x2in) ceramic rectangle upon which there were two smaller ceramic squares, upon which were various miniature resistors and capacitors and two to three transistors each. Someone had constructed these "integrated circuits" as building blocks to something bigger. My ten-year-old mind didn't quite understand all of it, being some kind of operational amplifier. But I did understand the idea of miniaturization. As a gift, I eventually received a Radio Shack 150-in-one electronics kit, increasing my love for the seemingly endless possibilities of electronics and computers. This realm of quantum computing seems every bit as nebulous as electronics was during the dawn of the digital age. I know quantum experimenting can be done online. But I feel like there ought to be some crude little quantum computing experimenters kit that can be given to children. Surely that would be a mind-bending gift.

Greetings Mr. C.B. I agree with your point of view. Quantum Computing will be a reality most probably as remote services built in sum with classical computing, helping products and services to rise to a higher computational level.

[waynerobarge]

Thank you for a well organized and presented update. I laughed at your reference to those who feel quantum computing will never be a real thing. How I remember my fellow colleagues who swore on a stack of bibles they would never have a computer on their desk and do their own word processing. That lasted about 5 years once the Apple II's and PC's were available.
