Mind-blowing explanation - Delayed Choice Quantum Eraser

Man, shut the hell up.....

[thegmanyo]

Thanks for the video; I can now play billiards like a master.

[omartron]

man, i must say, i am pretty baked.

firstly, man you are baked hahaha

I haven't watched all the vid, but after a deep stoned conversation with my brother, realised that man, we are all just cells along for the ride. every action/reaction that ever happens is all just cells interacting, we are all ...things for want of a better word, that are present, all on the ride i like to call "time" which leads to the ultimate fact that... we all need to chill out man (H)

i thought you're stoned so man

[LilDrummerBoy74]

"Thats so weird. They're freakin' not real" My thoughts exactly xD

[FreeLanceDoc]

@zimri19 that's what I was think too. Isn't that what happens when objects are sent at the speed of light (or near it?) maybe that's why there is such a low possibility it "leaves" the box; because every once in a while, the electron gains speed somehow to exceed the speed of light therefore propelling it out of our dimension.. If I'm not mistaken

[muaythaijunky]

so wait. electrons dont exist? iv studied the double slit experiament and all that and majority of what your saying but i havent seen or heard on this one. mind you i have no college education and study this stuff for fun on my own time. also on the sound traveling can some one tell me more on that?

[Cheuvin]

JUNTION

[zimPol06]

thus this creates infinite probability and randomness?

[omartron]

@zimPol06 totally man

[zimri19]

when seeing this video, i believe it does not behave randomly or strange in any way, but it's just moving normally with an extra dimension we can't (yet) see/understand.

in that case, it would not even need to go through the wall, just like we wouldn't have to move through walls in 'flatland' as we could just ignore the wall completely by going above or below it.

[longshotnl]

i designed a quantum eraser.

i want to show it to you but don't know how to send an image...

[cunnidvd]

what do you have in your mouth?

[wordzly]

John Wheeler said that QM is "the great smokey dragon:" the tail is where the particle is emitted, the head is where it bites the detector, but its body is shrouded in the Uncertainty Principle & shielded by complementarity. In Richard Feynman's Sum-Over-Histories view, the dragon gets from here to there by wriggling thru every possible point in between. Of course, Many-Worlds & Hidden Variable advocates have different interpretations. No one really "understands" QM.

[armondikov]

I think saying "the electron doesn't exist until it needs to" is taking the Copenhagen interpretation far too literally - after all it's just one interpretation of the probabilistic nature of quantum theory. The probability distribution, or at least its complex conjugate, is a real thing and represents electron density (very useful for atomic and molecular orbits). Particle-wave duality doesn't necessarily mean that electrons swap between being particles and being probability waves at will.

[architectus777]

@armondikov Josephson junction proves that the electron is not there until it is there. Then suddenly it exist on the other side of the wall, without every going through the wall. This device wouldn't be possible if the inventer didn't take the probability wave literally.

[armondikov]

@architectus777 The effect you're describing is quantum tunnelling; the wavefunction decreases through the barrier exponentially. If you have phase coupled electrons they would effectively generate a node in the centre of the barrier, but that's not the same as it never passing through the wall - you'd just have a region of zero electron density at the node itself. This would be odd if electrons were entirely particles, but they're not.

[architectus777]

@armondikov They never pass through the wall because they existed as a probability wave, which we could call an unreal thing. But something must be making all those calculations behind the scenes, which is why lots of intelligence people, including physicists are leaning toward digital physics.

[armondikov]

@architectus777 It doesn't follow that something needs to be making the calculations in an unreal sense. Quantum mechanics is just a mathematical description of phenomena that we observe, there's no reason to think that electrons travel around the Schrödinger equation somehow tattooed on them. Consider the path of least action, which works fine for describing motion, but appears to suggest particles are intelligent - which isn't the case, as Newton's laws can predict the same thing.

[TheGuyWhoToldMeToTel]

@armondikov I'm going to have to agree with armondikov's view about quantum mechanics. The mathematics describing particle behavior should not be taken literally with every step, the end result is truly the most important part. After all, it is mathematics that describes nature, not the other way around.

[TheGuyWhoToldMeToTel]

@TheGuyWhoToldMeToTel Just because I use one operator to "eliminate" a particle from a certain energy level and then another to make it reappear on another energy level doesn't mean the particle first disappeared and then reappeared. It simply means that, unlike nature, I could only perform one operator at a time... I do however find this video very helpful as well as the ongoing argument about probability waves and quantum tunneling. Keep up the good work!

[aryarish]

@armondikov they never pass through the wall at all, the electron is at all of those places at oncey, so it cant really exist the way you are saying. it exists as a probability wave not as a electron particle, until you might happen to find it while looking at a certain place.if we find the electron on the out side, it doest mean that one moment ago it was right next it its current position but farther back in its "trajectory". it could have been anywhere moment ago.

[aryarish]

@armondikov going through wall applies to trajectory, (a particle property) which goes against the whole idea. it cant have particle properties until it acts like particle which only happenes when we look at it on the outside.

[Vondaz21]

Much respect, I clicked a random video and with no knowledge of this topic or it's purpose I understand. I get exactly what you're saying.

[angelicearthling]

cool...but can you say "Josephson Junction" really fast 10 times in a row. Now THAT would be impressive. :)

[AmyHands88]

Very interesting. Can't wait to see The other videos.

[TheMasscox]

do other 'particles' like protons and neutrons obey the same Probability wave rules?

[architectus777]

@TheMasscox Yes. Even a carbon 60 molecule.

[TheMasscox]

@architectus777 woah.

[TheGuyWhoToldMeToTel]

@architectus777 I heard researchers are attempting to achieve the same results with bacteria. This is definitely an exciting period in history to be alive.

[rubinskio]

You were born to teach my friend

[Nifden1]

I ACTUALLY liked this.

[sgtbuckwheat]

Bad Quantum joke: Heisenberg is driving down a road and is pulled over by the police. The police officer walks up and rhetorically asks "Do you know how fast you were just going there?" Heisenberg replies "No, but I knew exactly where I was."

Its good to see other people are as interested in this as I am. I'm not a quantum person, I'm more of an analytical or synthetic chemist, but quantum is fascinating.

[royalconcrete1]

clever boy

[themaninblack951]

hmm...this was explained very nicely! Just wondering though. You use to have long hair? cuz when i watched the vids about alien predictions i thought i seen long hair lol! I loved those vids.

[francerulzv99]

@themaninblack951 Haha yeah, he used to have braids, a full goatee and sunglasses. I don't know when or why he got rid of it all :p

[architectus777]

@francerulzv99 I hated caring for dreads. Goatee comes and goes. I just get bored of it and shave it. Then eventually, I desire to have it back, so I grow it out. Sungless I wear often, especially in very lit places. :p
