THE QUANTUM REVOLUTION - Visions Of The Future - BBC

The quantum revolution could turn many ideas of science fiction into science fact - from metamaterials with mind-boggling properties like invisibility through limitless quantum energy and room temperature superconductors to Arthur C Clarke's space elevator. Some scientists even forecast that in the latter half of the century everybody will have a personal fabricator that re-arranges molecules to produce everything from almost anything.

The major stumbling block with Teleportation is the "Uncertainty Principle" which theorize that you can never tell for sure where a particle (like an electron) is actually located inside an atom.

Electron pops out everywhere in the sub-atomic world.. sometimes existing at the same time at different places.. you cant even measure their speed and position at the same time..

Sub-atomic world is a chaotic fucked up world. LOL

When they were talking about teleportation, what did they mean by information? I have trouble understanding what people mean by information when they talk about (e.g. photon) in the case of this video. Hopefully, somebody will reply me with a good answer soon but too bad very few people watch this video.

[AtheistsAreSkeptics]

@KoreaRwkz

The term "information" is actually being referred to how all atoms are arranged...

So if you are going to be teleported, the teleport machine must scan your body first to obtain "information" about how all atoms are arranged in your body so that your destination teleport assembler can "assemble" your copy exactly the same like you.

[KoreaRwkz]

@AtheistsAreSkeptics Oh. Thanks for the explanation. However, I've watched another video about blackholes where Stephen Hawking and other physicists were arguing whether information will be lost if a person is sucked into a blackhole. It was finally concluded that the information of the person being sucked into the blackhole will be smeared at the event horizon. Something like that. I don't quite remember. But is the 'information' that they're talking about still the arangement of the atoms?

[AtheistsAreSkeptics]

@KoreaRwkz

It was dubbed the "The Black Hole war" between Stephen Hawking and Leonard Susskind.

I even have difficulty understanding what these geniuses were talking about the preservation of Quantum Information.

This "Quantum Information" is similar to the one's that was being discussed in Teleportation.

And I think Quantum Information is far more complex than just the arrangement of the atoms.. it explains even the sub-atomic world..

Do a little research Im no good at theoretical physics :D

I was watching a video from the 1930s about future predictions of the year 2000, and most of the stuff they envisioned was way off from what we have today. The computer and many other things hadn't been invented during that time so their assumptions were based on what they had then. Which brings me to my point that we are making predictions of the future based on the technology that we have today, but we will never know for sure what we might invent next.

[ASexyChef]

@AtheistsAreSkeptics They talk about the same thing right at the end, guess you should watch the full thing before you comment.. So never-mind my statement..

[ASexyChef]

@AtheistsAreSkeptics I think the end process if you could teleport would become the major issue with it. Is the person you but into it, the same that would come out of it, you first have to destroy whatever it is your trying to teleport to reassemble it in another place, how would you save the memory, would you have to download your mind before you start the process and upload it at the end? Would that be more like just making a clone of yourself while killing/destroying the original?

[letsgetverydrunk]

high-jacking nature to make nanomachines... makes hippies very mad.

[2eelShmeal]

@2eelShmeal The idea that observation breaks down the wave function is one of those things that is derived from experiment. That's just the best explanation right now. People try to say our minds can control reality. Bullshit. Maybe OUR reality...

A lifeless mechanical detector will also break down the wave function it turns out. Something else is going on that we don't know so people think it's mysterious, (DEEPAK) like it has to be ESP or some shit. I guarantee there's a simple explanation.

[2eelShmeal]

@CONT. ie: So-called 'virtual' particles. I don't FOR ONE SECOND believe that particles appear (from nothing) then disappear (back to nothing). What's there is called the 'vacuum energy'. (I think) It's out of this energy that the particle form, then return to. They don't just materialize out of nothing.

I think it's even possible that the particles really are still there, but out of our detection. We are on the fringes of what is possible to know. In 100 years, QED may still seem mysterious.CT

[2eelShmeal]

@AtheistsAreSkeptics You know, I wonder if the reason QED seems so 'spooky' is because of our ignorance. The two slit experiment doesn't freak me out one bit. I strongly feel that there is a limit to what we can observe so anything beyond that point will always seem mysterious and even magical.

If we look at the history of science, everything was mysterious until understood.

The problem is we are reaching the limit of what we can see and so we are misled. (WILL CONTINUE)

I would say memory and personality are seperate from atoms and those things only exist when the brain is in its current configuration, should you smash up and destroy the brain in any way you would lose those two crucial things.

If true then even if you was to teleport someone when they arrive at the destination they would be like a new born baby in an adult body, they'll not know who they are, they will have forgotten how to walk,talk or do anything.

[MDEMONIC689]

@AtheistsAreSkeptics

IMO that is not THE problem i think the problem is that when you break up somebodys configuration and put it back together you have to ask "so how did we teleport the mind, memory?"

If i smash a brain into atoms those atoms are no different to the atoms of a tree or a park bench or a glass of water so even when you re-assemble something back into a brain where did the memory and personality come from?

I was immediately more interested when I saw Michio Kaku in the thumbnail. Not to say I wasn't very interested in the first place.
