Are quantum computers the game-changer they’re described to be, or is the promise of exponential speedup overblown? Join pioneer Seth Lloyd and Brian Greene as they discuss how the fundamental principles of quantum mechanics are leveraged by quantum computers, and the algorithmic challenges in achieving the promised exponential power.

but the caption was never answered, or is it in superposition?
Seth Lloyd is the great great great grandfather of the evil twins in Matrix Reloaded
Penoso.
Agreed
Hey, I actually have a question for everyone in the comments who wants to share their opinion.
Is it worth starting my career in quantum computing right now?
I have been programming for 6 years, and I’m finishing my BSc in Computer Engineering in one year. However, AI has made me skeptical about continuing in traditional programming, so I’ve been considering moving toward quantum computing and starting studying it right now.
What do you think, should I invest my time in the field?
it's right around the corner…hangin out with fusion power.
So you get 2^n operations from quantum computer for n-bits ….. what these operations are, and how to extract the correct result?
A classical computer performs 3 basic ops: NOT, ADD, SHIFT one in one clock cycle…. on n-bits at a time .. All other operations can be performed by algorithms using these basic ops. What qtm computer can do at fundamental level, and how it can extend to more complex ops?
What are any basic/simple problems qtm computers have solved up till now, as examples?
wave particle duality —— something similar to Energy to material conversion(fusion , fission.) but at miniscule scale.
But a wave isn’t one particle, its a collection of them. The gun in the experiment needs to be able to shoot individual particles which if the experiment matches a wave it did not. I have never seen this talked about and this issue talked about. I don’t even know how you could program a gun to pulse at the Planck length but it’s what you would need to have an objective non-biased test.

I'm sick of this ridiculous two slit experiment. The "HOLE" that the photons emerged from is the same diameter as the back plate. Even if you don't think so. Sigh.plz enough with this silliness.
Holy particles batman
Cymatics. Light has them. Flowers. Why's that spooky? One had mass, the other does not. E=what now? A new atomic equalizer.
Seth Lloyd is a great scientist. He invented hhl algorithm which consists of a chain of bottlenecks. This is a really impressive result. He also invented trotterization of evolution operator, which was known from 70's in the field of nuclear magnetic resonance. Follow him and you will learn many other exciting things.
There is a massive snooping scam involving tech companies and the governments. They created AI to blame it on.
Charles Barkley: "Seth Lloyd, come on home, man."
The slit experiment os just like a lot of zombies running through two openings, falling over eachother and the hitting a wall.
The difference is, that's it's a lot of them, the slit's are very wide, they can't be stopped and even better, they are and always will be traveling at the speed of light until they uit the wall.
10 years minus 5 plus never 😂😂😂
With the slit experiment, what happens when you have one slit or when you decrease and increase the particles, or even a double slit but just one photon?
Science, the wave-function and alike, allow us to predict behavior that we can observe through the filter of our human perception and thinking (our human mind, the space-time conceptualizing machine). That way, the ‘wave-function’ needs to be understood in epistemically way, but not ontic. Quantum Mechanics allows us to predict cause and effect with astonishing precision, it tells us a lot about how our ‘conceptualized nature’ behaves, but NOTHING about WHAT REALITY ACTUALLY IS. This is simply beyond the scope of materialistic (objective) science.
This is a guy that is operating on all cylinders. Very good and BG as always is awesome.
Einstein was wrong about the aether; that it existed. Both Einstein and Spinoza believed in a God that was manifest only; they did not believe that God was also transcendent, so no need for a barrier between dimensions. Beliefs likely affect and influence the worldview of even great minds.
Will our tech be accessible to all our senses is what was intended to be expressed in prior comment.
Quantum Computation. Bah. Can it solve ‘the hard problem of consciousness’ for philosophy and if mind is differently elemental and emerges with quantum events with the macro elements? And can more than sight and sound (all of our five senses) be brought into our living space? That is what we want to know.
Is he the scientist from idenpedance day😂😂
The weirdest part of the double slit experiment is that if it's observed, it behaves like a particle, but if it's measured without an observer, it behaves like a wave.
Two brilliant men! I don’t like quantum mechanics. It gives me indigestion.
Must AAsk about Direct God power Body of His iff you emegin comprative a Quantuam power" ??
Regardless what people wanna call it. If it's superior to modern computers? It needs to replaced just like any other technology that's been replaced by more advanced electronics.
Keep your glasses on.
This bloke needs to let the guest speak.
Autocad with extra chromosome with quantum, reading my 68th book now.
My guess is that they are in spin up and down but not equally, and the measurement tool forces it to choose one, which causes it to align with the strongest spin (up or down) it's not that difficult to grasp.
is he bald or does he have long hair?
Different dimensions. Reminds me of CERN. PLAYING GOD.
EGO. PRIDE. THEORIES ARE GUESSES.
Demonic
I love how he used the double slits as zero and 1 as an analogy for the Qubit.
I am using my Quantum computer to watch this.
I gave this video a thumbs up and a thumbs down. I subscribed and didn't.
Ok good it is still me in this branch of reality, the other me is not subscribed, they will miss out.
When does the single drop? 🎙️
