Can anyone explain me ; -
What is quantum entanglement and how it effects the space-time and matter in our universe??

Check out the wikipageDhruv007 said:Saw a lecture on it on YouTube. But didn’t quite understand it.

In general it's an advanced topic, so you should have taken a Quantum Mechanics course before venturing into it.

Right, but like I said, this is a very advanced topic and if you don't have any physics background it will not be possible to understand. Start with mastering classical physics first.Dhruv007 said:What i want to know is ;-
Why does it occur and how does it occur.

So after reading the wiki page, what are your specific questions? The page does touch on "Why does it occur and how does it occur."Dhruv007 said:Dont worry. I have a stong background

Then it could be a little tricky, but I'll give it a try...Dhruv007 said:I haven’t taken any courses on physics. Just read and understand stuff that seems interesting to me.
Quick and dirty: A measured correlation of the properties of two objects, regardless of e.g. the distance between the objects.Dhruv007 said:What is quantum entanglement
This is not entirely clear at the moment, it is being thought of and studied.Dhruv007 said:and how it effects the space-time and matter in our universe??
Why? Because that is a feature of our Universe.Dhruv007 said:Why does it occur and how does it occur.

I get the definition thanx.

I thought so.

So basically, we have no idea about why entanglement exists, so we call it a property of our universe.
How? See e.g. SPDC (which is an example)
SPDC was quite simple to understand. Thanks fot recommending it.
You can watch this clip, where the quantum physicist Anton Zeilinger describes entanglement (at 1:30 into the clip and onwards) and a variety of experiments/applications:
Anton Zeilinger - Quantum Information and Entanglement
You can also have a look at EPR paradox.
Yeah, but the same goes for every other physics concept; we have no idea why [insert any physics concept here] exists, it is a feature of our Universe.Dhruv007 said:So basically, we have no idea about why entanglement exists, so we call it a property of our universe. . (my bolding)

I further recommend Richard Feynman who in this video elegantly describes the problems with "why questions":
Quantum entanglement is a phenomenon in quantum mechanics where two or more particles become connected in such a way that the state of one particle cannot be described without considering the state of the other particle, even if they are separated by large distances.
Quantum entanglement occurs when two or more particles interact and become entangled, meaning their quantum states become correlated. This can happen through various processes such as particle collisions, photon emissions, or interactions with an external force.
Quantum entanglement has significant implications for our understanding of the universe and has potential applications in quantum computing, cryptography, and teleportation. It also challenges our traditional understanding of cause and effect, as entangled particles can affect each other instantaneously regardless of distance.
Quantum entanglement has been shown to exist across large distances, even on a cosmic scale. This means that the entangled particles are not bound by the restrictions of space and time, and their entangled state can remain intact regardless of the distance between them.
While quantum entanglement has been shown to have potential applications in secure communication, it cannot be used for instantaneous communication or to transmit information faster than the speed of light. This is due to the fact that the entangled particles themselves cannot be used to transmit information, but rather their correlated states can be observed and measured to infer information about the particles.
