What percentage of particles in the Universe are entangled?

Can a particle be entangled with >1 other particle?

What causes 2 particles to become entangled?

What causes 2 particles to become unentangled? Is unentangled even the correct term?

Are atoms entangled? or are only sub-particles entangled?

Are there any particles that cannot be entangled?

Are particles within a BEC entangled with each other?

I have more but will stop there.

Thanks in advance for taking the time. :)

:) :)

i'm hoping that there is someone in our community that may be able to share their knowledge on this topic.

Quantum physics strikes me as something people on the spectrum could take a special interest in. It's all well and truly above my head I'm afraid.

Thanks for reading the thread.
These things are beyond me also, hence my questions.
If I am capable, I would like to understand the topic.
I will certainly try.

Nobody knows, we can't exactly measure every particle in the universe to know how many are entangled. That's almost like asking how angels can dance on the head of a pin.

Yes, more than 2 particles can be entangled with each other. In fact you can get whole systems of particles that are entangled with each other. There's no limit to how many particles can be entangles with each other, it's just that the system of entangled particles will become more complex the more particles are in that system. In a laboratory they've managed to measure up to 4 entangled particles.

slave wrote:
What causes 2 particles to become entangled?


It depends. Sometimes particles become entangled due to an interaction they had with each other and sometimes entangled particles are the decay products of a heavier particle or share a common origin due to pair production. For example, if an electron and a positron are created via pair production from a single photon then they will be entangled.

slave wrote:

I'm not sure that I would call it unentangled but it's quite easy to destroy the correlation between 2 entangled particles. For example, one of the reasons why it's not possible to use quantum entanglement for faster-than-light communication, regardless of what they might say science fiction, is that if you try to manipulate one particle in an entangled pair then that just destroys the entanglement instead of allowing you to send information to the other particle. Entanglement is also destroyed by a phenomenon called decoherence which happens when quantum information from a single system seeps into the environment. Decoherence is also an explanation for apparent wave-function collapse.

slave wrote:

Atoms can be entangled as well but since atoms are composite systems of more fundamental particles, I'd suspect that entanglement between atoms would be more complicated than say, entanglement between 2 photons.

slave wrote:

Not as far as I know. Entanglement is a fundamental feature in quantum mechanics, so I think that any kind of fundamental particle could be entangled. However, entanglement becomes much less likely on the macro scale because the more particles you have in a single system, the more likely that they will decohere.

slave wrote:
Are particles within a BEC entangled with each other?


Not necessarily, although the properties of a Bose-Einstein Condensate is a macroscopic quantum phenomenon. We get a Bose-Einstein condensate when a gas (or liquid as in the case of superfluid helium 4) gets cooled to near absolute zero so that most of the particles in the system (or even all of them) end up occupying the same quantum state. So obviously quantum effects will become much more apparent on the macro scale in a state like this. There is some work being done in the generation of entangled states within a BEC as part of research into quantum information though. Apparently, it's much easier to entangle a large number of particles within a Bose-Einstein condensate than in ordinary matter, for example see here:

There is a recent work that suggest that quantum entanglement may be from a particle stuck in a wormhole and the "two" entangled particle"s" may be the two mouths of the wormhole. http://quantumfrontiers.com/2013/06/07/entanglement-wormholes/
It could open the door to a new physic linking quantum physic with general relativity. Sadly this would also mean we should say goodbye to the idea of a wormholes network that would allow FTL communications and travels. :(

I'm a wannabe physics guru and wish I had just studied physics in high school so I chose a better science course in uni, but I was too put off by the math. That and my f***ing science teachers would always get angry with me for confusing the class, asking questions beyond the scope of the course and criticising me for being "to precise" rather than guiding and encouraging a development of my scientific interests. I dropped out of school after year 10 and didn't start uni until I was 25. I studied biology, but I still can't finish it, because I keep clashing with the teachers and the institutions over their sloppy delivery of the course materials. A few were good. Most were bad.

I wish I had the support and opportunities now to pursue this interest. I wish there were some sort of aspie-geek-nerd society I could join to exchange all this info with others in an accelerated perseverated fashion. I live in the Australian outback where everybody wants to just drink beer and watch the footy. I like beer and footy too, but nowhere near as much as I like delving into the deep mysteries of the universe.

I'm dying for this on a really deep level. I'm seriously thinking about selling my two houses, leaving my NT partner and heading to Geneva on a grail quest. I have no attachment to this empty life. I crave fulfilment so badly, and I'm just not getting it.

I don't know if it would work out though. I have a hard time getting in the Vortex these days. I feel really jaded :(

I want to be friends/mates with a quantum physicist like Sheldon Cooper. That's probably my ultimate fantasy. Just to have another mind who thinks like me to teach me all the stuff I've ever wanted to learn, and to question and explore the mysteries of the universe together. That, to me is much more intimate than all the stupid romance stuff. But I suspect such a person would be more likely to want to work alone.

I feel so damn lonely in this world. Definitely the wrong planet for me.

OMFD, do i ever relate to what you are saying 8O :!: :nerdy: :!:

I could learn so much and so quickly if i just had someone with whom i could engage intensely(read continuously :lol: ) with focused questions from me and guidance and expertise from them.

I crave the deep, like you. :nerdy:
I do not have of way of fulfilling this need, like you :nerdy:
:( :( :( :( :( :( :( :( :( :(

I hope you somehow find what you crave.

Everything is entangled at least a little, nothing is something on it's own
so it's about looking for the right expression, formula to put on it.
(no ph-guru here)
but one might keep in mind science is about consensuses, or agreements on formula's, which is logic for communication purposes
....but boring to learn!
I could understand physics but not learn to remember all that, anyway it didn't matter if you understood, after that you were supposed to learn by heart the formulas and do the math with it, I really couldn't be bothered doing that, why? you have books and calculators (slide rules in my time) for that.

In a sense "atoms get entangled with other atoms" by a different mechanism than subatomic particles get entangled witth other subatomic particles. When atoms get entangled theyre called "molecules".

Thanks Slave, it's good to know I'm not the only one floating out there in outer space. I'm devouring information on the human brain right now (specifically how disconnected brain regions manifests as autism, schizophrenia, sensory processing disorder etc), I totally wish I could mine the information in a more accelerated fashion. I've been studying savants, too. Kim Peek (Rain Man) has agenises of the corpus collosum. He is like an extreme version of how hungry my mind is for information. They call him the human Google now. Only recently has he begun to connect facts to one another. I'm constantly connecting them. Like Temple Grandin. "I'm not like other people. I think in pictures, and I connect them".

I wish I could dl the entire internet through a fiber optic hose :lol: :lol: :lol: :nerdy: :nerdy: :nerdy:

Kim Peek is deceased(Dec, 2009) a truly remarkable man we lost. :(

Hahaaa fibre optic hose ROFL! I always said getting the NBN connected (Australia's high speed fibre optic network FTTP - Fibre to the premises) was like getting fibre to the vein. Just IV download of information hahaha

Kim Peek died?!?! Oh man now I'm sad :cry:
I wonder if it had anything to do with his dad… now I gotta go google this…
