Quantum Entanglement: How to Create an Entangled State #shorts

#shorts about how simple it can be to create a quantum entangled state!

But one question that crops up a lot is, how can we CREATE an entangled state? For example, if we have two electrons, how do we entangle them? Well, I discuss that quickly in this video. One theoretical way to do this is to have a particle with zero spin split into two particles that have spin (such as electrons).

Because spin is a type of angular momentum, the Law of Conservation of Angular Momentum must hold. In other words, the total spin of the two new particles must be the same as the spin of the original particle (zero). So if we find one of the new particles to be spin up (along any measurement direction), then the other particle MUST be spin down (along the same direction). This way, the spins of the two particles are opposite to each other and the sum of their spins is zero. Angular momentum is conserved.

For those who want to know how we split them:-
Project a high intensity light from a light source to a nonlinear crystal, they will interact with each other after passing through non linear crystal and will form two photons(both will have half frequency or double wavelength) that we call signal photon and idle photon, these photons are entangled now.
Additional information:-
We have never found any two particles entangled naturally, we have entangled particles artificially, and finding a pair naturally might be possible but in very rare and extreme circumstances if possible.

You explained quantum entanglement in less than a minute and it took my lecturer an entire semester.

Bravo 👏

[dpmkumar]

I am impressed by your teaching style 🙏🎉

The problem with shorts is that they need to be really short. If they are not then it's just a video that you can't rewind if you miss something.

I’ve never understood why this is so spooky. They aren’t influencing each other, you’re measuring one and inferring the other.

There is a delightful subtlety in using a spin-0 particle to create two entangled spin-1 particles. If a spin-0 particle has a known internal structure that affects the polarization of the formed spin-1 particles, the emitted particles may not be entangled after all. For example, suppose one can prepare spin-0 para-positronium so that the internal spins of its positron and electron are known. Then for at least some angles, the gamma photons emitted when the positronium atom decays may not be entangled at all.

Given that billions of U.S. dollars are going into quantum computing research these days, that's important. Suppose a group uses pair creation methods that indirectly create external information on the polarization angle of the pairs. In that case, they could attempt to compute using pairs there were never entangled in the first place.

I thought it has something to do with law of attraction...but you explained it so well...

A different type of "Entanglement", which produces the "Strong" force.

Quantum Entangled Twisted Tubules:

When we draw a sine wave on a blackboard, we are representing spatial curvature. Does a photon transfer spatial curvature from one location to another? Wrap a piece of wire around a pencil and it can produce a 3D coil of wire, much like a spring. When viewed from the side it can look like a two-dimensional sine wave. You could coil the wire with either a right-hand twist, or with a left-hand twist. Could Planck's Constant be proportional to the twist cycles. A photon with a higher frequency has more energy. (More spatial curvature). What if gluons are actually made up of these twisted tubes which become entangled with other tubes to produce quarks. (In the same way twisted electrical extension cords can become entangled.) Therefore, the gluons are actually a part of the quarks. Mesons are made up of two entangled tubes (Quarks/Gluons), while protons and neutrons would be made up of three entangled tubes. (Quarks/Gluons) The "Color Force" would be related to the XYZ coordinates (orientation) of entanglement. "Asymptotic Freedom", and "flux tubes" make sense based on this concept. Neutrinos would be made up of a twisted torus (like a twisted donut) within this model. Gravity is a result of a very small curvature imbalance within atoms. (This is why the force of gravity is so small.) Instead of attempting to explain matter as "particles", this concept attempts to explain matter more in the manner of our current understanding of the space-time curvature of gravity. If an electron has qualities of both a particle and a wave, it cannot be either one. It must be something else.

I like it! Well explained and I want to know more. Off to the main channel I go! About time we got another decent science youtuber around here #Subscribed 🚀

That good explaination of the effect YOUR leaking the fine details of causes

Nice little video ... apart from the "particles behave as if they were spinning" ... um ... no, that isn't what "spin" is.

[DrDeuteron]

Every atom bigger the hydrogen is entangled. You think one electron is in a specific orbital? Every nucleus bigger than a proton is in a entangled state. Look at a deuteron. Spins are aligned, but isospin is not. That means: pull a nucleon out and it's 1/2 proton and neutron (until you look). A proton is an incomprehensible entangled state of QCD mess.

[makanani]

Literally just described the breitt wheeler process.

[chriswatts]

And suddenly it clicked! The whole reason that spins are conjugate with each other is conservation of angular momentum.

[manishgupta]

So what is the physical implications of. Quantum entanglement? How does one cane benefit from this concept?

[prashantlale]

Hey i like your new set up
It's cool👍

[borisv]

Spin angular momentum should be shortened to SPAM

[husky]

Parth, can you please consider explaining the process to entangle, say, two calcium atoms? I hear it’s done with lasers, but and ….magic…. If you could fill the blanks, then I’d use that to ‘splain it to my crypto students. Most grateful
