Seth Lloyd - Quantum Mechanics Experiments

Quantum theory has been the most powerful explanation of how the world, down deep, really works. But quantum theory is weird: things in two states or places at the same time, probabilities not actualities of events, entanglement over vast distances. How do precise, repeatable experiments support such counterintuitive concepts?



Seth Lloyd is a professor of mechanical engineering at the Massachusetts Institute of Technology. He refers to himself as a "quantum mechanic".

This channel goes from strength to strength. I loved understanding more about how quantum computing will change things in just the coming 3 to 5 years, let alone the coming decades. This is such an exciting time in this field.

The folks working on practical experimentation in quantum mechanics and the theorists are wildly important as is their work and desire to understand at both the complex levels wnd the simple ones. If you cannot explain it like this conversation, you still don't get it. Vastly complex and simple at the same time. Very cool convo.

The people quietly passing on those rafts have no clue they just drifted past two of the most interesting people on earth.

This is boss man! Every single day I'm picking up something new. Seth Lloyd offers a slew of information!

[markring]

I’m not a physicist. Just a curious layman. I enjoy these types of of conversation. What I have yet to hear is real world, everyday results from these experiments in quantum computing. I’m excited and hopeful for this to happen. I’m in my 60s. I’m sadly confident that we won’t get there in my lifetime.

Seth is looking better here. He is using better examples and being more coherent to everyday people. In the past he's gone to la la land and you couldn't follow or make sense of his bad examples and incoherent talk. When you work with QM all day I imagine you see the world in a different way, but you have to make sense of it all and learn to communicate it in a coherent and rational way for people to follow. He has gotten much better at this and I hope he continues to work on this and communicate this type of stuff better to you and I more as I enjoyed listening to this version of Seth.

Wow… When you think about and process “Exponential” it almost makes me fall over… Both Physically if I’m not sitting down or mentally- seeing 100% Abundance From “INTELLIGENCE”… I’m just getting started on my computer science adventure, I’m very excited… I think I should have a very good understanding between now and 3-5 years of learning programming; e eventually I Am going to learn “full-stack”… I don’t like being ignorant, it’s embarrassing… Hahaha, not for long… My Numbers are Machine Language, I can’t wait to learn everything I can because I’ll be creating all kinds of “New” stuff… I guarantee it…

Just imagine the accuracy of 1/10.000 of the diameter of a proton!

Cauld it be possible to change "the binary entangled particle systems"to create "molti- entangled particle systems"?.

[jamesruscheinski]

have quantum computer predict what quantum computing will be like in 20 or 30 years?

[Clancydaenlightened]

What happens if two black hole become affected by spooky action at a distance

Could black holes be the ultimate form of a "quantum computer", I mean it's really the only representation of infinity that exists in the known universe

[BenjaminGatti]

Very few quantum experiments have publicly disclosed data. Hint, Einstein's epr paper is holding up just fine.

[SandipChitale]

I wish Robert had asked Seth if the labs that develope quantum computers worry about the consciousness of the lab personnel in the room to collapse the quantum state. And if the answer is no, which is likely the case will once and for all put end to the myth that consciousness is REQUIRED to collapse the quantum state. A macroscopic, conscious entity can collapse a quantum state not because it is conscious but because it is macroscopic.

[jamesruscheinski]

do quantum effects make larger systems more uncertain and chaotic?

[benji.B-side]

As long as a Quantum computer boots up faster than that a Microsoft Windows PC, I'll be happy.

[charlesrothauser]

Is there a threshold between the quantum world and Newton's world?

[jamesruscheinski]

will quantum computers be able to take in data from environment as input by themselves?

[Tokinjester]

does Seth spill the beans on his (successful!) _time travel_ experiment?! :p

[turnerthemanc]

Did either of them notice the beautiful scenery once, or were they so entangled (no pun intended) in talking about what doesnt exist that they missed it.

[markberman]

The concept of running information in circles against each other while held within magnetic fields is actually very old though never understood, certainly not in this context or level of knowing the how's and why's. What if we could slice and layer the ones and zeroes within this environment? Would that not be an un-estimatable increase in processing power? Has this been thought of? Section, slice and layer in a nearly undetectable manner except within the system, might be an interesting thought experiment, no?
