Quantum Entanglement:

Consider throwing a ball straight into the air.

Is it possible for us to predict the motion of the ball, after it leaves our hand?

Sure, the ball will move upward until it gets to the highest peak, then will come back down and land in our hand again.

Of course, that's what happens, and we know this because we have witnessed these events countless times.

We've been observing the physics of everyday phenomena our entire life.

However, assume we investigate an inquiry concerning the material science of particles, as

What does the movement of an electron around the core of a hydrogen atom resemble?

Could we answer that question based on our experience with everyday physics or witnessed events?

Maybe the answer is probably NO!

But Why?

Since the material science that oversees the conduct of frameworks at such little scopes is very different than the material science of the perceptible articles you see around you constantly.

The everyday world we know,

Behave according to the Laws of Classical Mechanics

But systems on the scale of atoms act agreeing to the Laws of Quantum Mechanics.

The quantum world starts & appears up being a very strange place.

A visual of quantum strangeness can be understood by a famous experiment:

Schrödinger's Cat:

A physicist, who doesn't particularly like cats,

Place a cat in a box, along with a bomb that has a 50% chance of blowing (boom) up after the lid is closed

Until we reopen the box lid, there is no chance of knowing whether the bomb exploded or not, and thus, no chance of knowing if the cat is alive or dead.

In quantum physics, we could assume that before our observation the cat was in a superposition state.

It was neither alive nor dead but instead in a combination of the two prospects, with a 50% chance for each.

The same sort of thing happens to physical systems at quantum levels, like an electron orbiting in a hydrogen atom. The electron isn't orbiting at all actually.

How we didn't know regardless of whether the cat was alive or dead until we opened the case

This makes us observe a strange and beautiful phenomenon of Quantum Entanglement.

Assuming that there was not a single cat in a box,

We have two cats in two different boxes:

Now apply the same condition to Schrödinger's cat experiment with this pair of cats.

The possible outcome of the experiment can be one of four perspectives:

Either both cats will be alive,
or both will be dead,
or one will be alive
and the other dead, or vice versa.

The system of both cats is again in a position of superposition state, with each outcome having a 25% chance rather than 50%.

But here's the cool stuff: Quantum Mechanics rundown with possibilities to erase both cats alive and both cats dead outcomes from the superposition state.

In other words,

In a Two Cat System, such that the outcome will always be "One Cat Alive" and the "Other Cat Dead".

The technical term for better grasping is that the states of the cats are entangled.

Mindblowing Info about Quantum Entanglement:

We set up the arrangement of two cats in boxes in an entangled state, at that point we move the containers to the furthest edges of the universe, the result/outcome of the experiment will ultimately be the same.

One cat will consistently come out alive, and the other cat will consistently wind up dead, despite the fact that which specific cat lives or dies on is totally dubious before we measure the outcome.

Really?

How is this possible?

Imagining, How is it that the states of cats on opposite sides of the universe can be entangled?

You might be thinking,

But, It's is just some theoretical mumbo jumbo

This sort of stuff can't happen in the real world."

Well, this turns out that quantum entanglement has been confirmed in real-world lab experiments.

Explanation:

Two subatomic particles entangled in a superposition state, where if one spins one way then the other must spin the other orbit, the same happens here, in any event, when it is highly unlikely for information to pass from one particle to the next showing what direction to turn to comply the Rules of Entanglement.

It's not astonishing that entanglement is at the core or head to that of quantum information science.

A growing field studying

How to incorporate or work with the laws of the strange quantum world in our macroscopic world,
Quantum cryptography, includes the spies that send secure messages to each other, or
Quantum computing, for hacking ethically or cracking the secret codes.

Everyday physics may start to observe a bit more like the unusual quantum world.

Quantum teleportation may better progress and that day the cat will escape to a safer galaxy, where there are no physicists and no boxes, the outcome will be 100% live.

I know Quantum is not that easy, so if I'd committed any mistake in explanation please correct me.

Good To Go for new Exploration!

All the Best :)
