      Just as a basic understanding. but in the inner-most shell of an atom exist 2 electrons, one spins one way, whilst the other spins the other way, obviously if you can separate these electrons, you only need to find the spin of one electron to work out the spin of the other. This is my understanding and would love to be proven wrong to learn more.

      Help me understand better please. Could that particle automatically assume an opposite orientation- regardless of separation? So then it does not always have to actually change based on the other, but be what it is. Like if I rip a piece of paper in half- one piece is smaller, the other is automatically larger. It did not change- it was always like that.

    Yes, entanglement creates something spooky indeed. I think the part about choice in the matter, between Bob and Alice to discern the mystery of entanglement touches on it.
    Instead, choice-less awareness is key. Something humans have difficulty in understanding and maintaining because for millennia we have structured society around the observer not being the observed.
    I believe, that education of this sort can make choiceless awareness (in line with quantum) the natural perception of an individual and society evolve as such.

    Quantum Entanglement means you know that something is.

    Then you reset it the position of each particle within an absolute state: as in your giving them an option but setting them into a state of absolution. Quantum understanding gives us the ability to bring new concepts to old theories.

    Quantum Entanglement was first shown by the Stern Gerlach experiment in which their spins (an inherent property particles possess, like mass or charge) are opposite to one another after they have been entangled. Entanglement means instead of two separate particles doing their own thing, they are connected. There is no physical connection. No string or ropes joining them together. Instead, you need to remember particles exhibit wave and particle properties. Just like in the double slit experiment, in order to understand how a single particle can pass through both slits, you need to think of them as WAVES. Or to be a little more precise, mathematical constructs called Wavefunctions. So two entangled (or connected) particles are not two separate balls of matter, think of them each initially having their own wavefunction. After entanglement ,there is a single wavefunction that describes the properties of both objects, When the wave function is collapsed (ie measured) we can determine the spin of one, and therefore the spin of the other. There is no faster than light communication. We're talking about a mathematical construction - the wavefunction - nothing physical. Hope this helps a little.

    Light waves of a common source will have Quantum Entanglement with spin or polarization relative to new photon oscillations. This can be explained by spherical 4πr² geometry based on Huygens’ Principle: That says: “Every point on a wave front may be considered a source of secondary spherical wave, which spreads out in the forward direction at the speed of light”. This process is relative to the spherical surface that forms a manifold or boundary condition for the characteristics of quantum entanglement. The polarization or spin will be the same for the whole of the spherical surface. This will be observed as opposite spin on opposite sides of the light sphere.

    To "entangle" the coins in the analogy given....imagine you bond them to a rod with the coins at each end. When laying on a surface, the coins are bonded to the rod such that one coin is facing up and the other facing down. Random flip of the entangled coins on a rod assembly is like measuring the spin for example at one coin end. The direction found at the measured end is probabilistic, but the other end coin will always be found to be the opposite/correlated.
    The measured result at the opposite end apparently is "instantaneous"(faster than light). Are there any restrictions on how LONG you can wait and still get this measurement correlation?

    Alice's conclusion that Bob's coin toss turned out the opposite of her own is based on the presumption that both coins remain entangled with each other continuously throughout the period after they traveled apart. If so, then Alice's conclusion will turn out to be correct. Neither Alice nor Bob, however, can confirm whether that entanglement remained intact, and thus cannot confirm whether the outcome of Bob's coin toss was in fact determined by that presumed entanglement.

    OK, but can someone explain why we cannot do this scenario (or can we). Take 3 electrons, call them A,B and C - Entangle their spin such that A is entangled with B, B with C and C with A - now any measurement of particle A's spin results in a logical contradiction. If A is Up, B must be down and if B is down C must be Up .. which leaves both particle A and C in a Spin Up position. Help me understand. Thanks

    I still don’t understand if Entanglement means 2 coins are such pair that they are always opposite to each other then one head means other is tale.So once they entangled then it’s done one head and other tale is set no matter you measure it what distance and this is what I am struggling to understand if again I change one coin from head to tale does that set other coin tale to head ? If no then I don’t know what is confusing someone explain me please

      No, it doesn't. To stay in the coin example let's say the two coins are completely entangled. So one is always the opposite of the other. The correlation (or better anti-correlation) is 100%. Now let's say one of the two observers flips one half of his coins randomly, again. So one half stays entangled, the other half takes on a random value. Now the correlation of one half is perfect and the correlation of the other half is random (i.e. there is a 50% chance that it's correct and an equal chance that it's wrong). This means the correlation between the outcomes now falls from 100% correlated to only 75% correlated. It's still more than the 50% that we would expect if both observers would perform random tosses on each coin. That is what happens in quantum mechanics. We simple reduce the correlation between the outputs by introducing an additional "randomizing" process. The math doesn't work the same way as in the coin toss example, but the physics is quite similar to what I just said.

    If both entangled particles have super synchronization, both can have the effect as described as entanglement, but they are just synchronized not entangled.

    Thank you for taking the time to explain quantum entanglement and make this video. This video states we can’t use it to send communications but this other video says quantum entanglement communications already exists and they have working systems using it already. ruclips.net/video/2C1e2JedcBM/видео.html What if this is true? Will it ever be availability in the public sector? Ever since I first learned of quantum entanglement I envisioned scientists figuring out how to communicate with it. Just imagine no signal loss, no need for excessive power to amplify a signal, no delay communications from anywhere to anywhere. Real-time 8k video feeds from a spacecraft or probe / rover on another planet that can be remote controlled in real-time. Interstellar sensors that can warn us ahead of time of solar flares or other interstellar threats. Cell phones that work from anywhere not requiring a cell tower. The internet of things on steroids forget ip v6 hello ip v8 as we would need way more ip addresses to handle a world with so much connectivity. I hope I see this someday if the world can grow up vs blows up and resets again like so many civilizations before us that we know or don’t know about. Maybe we make it to a type 1 civilization and beyond or maybe we don’t.

    You're missing the point that the wave is collapsing when one person allows it to be measured. This is because both particles are described by the same wave.
    It doesn't violate Einstein's relativity because it takes time to move the once they're described by a wave across the world.
    You took a collapsible iron bar over the edges of the Earth It would take time to do that and it would obey relativity. The fact that we wouldn't know a property of it until we measured it It's not violate relativity.
    The real problem is that people speak like we have a particle of one spin and a particle or another spin. That's not accurate. Instead we have a single probability distribution that shows two locations where a particle might be measured with higher frequency.

Plenty of people understand this stuff just fine. The problem is that we don't have a good way of explaining it to the public. How, for instance, would you explain exponential notation to a kid who can't even count to ten, yet? What does 10^34 mean to such a kid? Not much, right? So how am I going to explain quantum mechanics to somebody who didn't have the attention span to memorize the definition of energy in high school? Quantum mechanics is all about energy. It's how nature really distributes energy between systems. Will the person who has no concept of what energy is understand how it is being distributed? Hardly.

However, popularization should not equate to trivialization or misrepresentation. The woman in the video describes phenomena that can be explained through classical correlations, whereas entanglement is more than that. To grasp entanglement, we have to consider Bell's inequalities; there's no way around them. But understanding them requires time and effort. Knowledge demands effort, and that's a message these people should convey -- instead of creating an illusion "Wow! Now I understand what entanglement is!"

    Of course, nobody ever explains exactly how entanglement is actually achieved. It's a load of bullshit anyway. Quantum mechanics is nothing more than a probabilistic mathematical framework based on the misunderstanding and the misinterpretation of the nature of light, and the double-slit experiment. Maybe that's why it is "probabilistic"... The math may be useful for replicating technology and chemical reactions, but it has no bearing on reality itself, because the theory is founded on the fallacy of quantum state superposition.
