Hey sci can you explain quantum teleportation to me... In easy steps plzzz

>> No.3924359

The wikipedia link is not understandable...

>> No.3924361

>>3924359
lol.

Also, Quantum tunneling != Quantum teleportation

>> No.3924366

>>3924361
Yes it is you fucking dunce. It is the smallest energy form of quantum teleportation so I advise you understand it before you try to create a fucking device to teleport you from your computer to the toilet you lazy neckbearded faggot.

>>3924357
what the fuck doe quantum tunneling have to do with entanglement?

>> No.3924373

Not OP, but we were discussion tunneling in my introductory QM class, and the professor said that within a barrier you have a finite chance of finding a particle, but it has no momentum.

Am I understanding this correctly?

What the fuck does Quantum Entanglement have to do with teleportation?

>> No.3924377

>>3924373
Generally we use the uncertainty principle to describe tunneling so yea.

>> No.3924381

I understand the part where photon travels from part A to B.. But how can its carry information? I,m familliar with computer systems where you have two choises .... 1 and 0. On and of by that creating a information source... But you can turn of a photon, and thats where i get confused.... Ops here btw

Quantum teleportation is the teleportation of information by quantum entanglement.

the photon can spin one way or the otyher, thats the 1 or 0. but it can also have any combination of 1 and 0. only when you measure it does it become 1 or 0. so if you have 2 photons and you know the must sum to 1, you know 1 is 1 and 1 is 0. so if you measure the 1 and find it is 1 you instantly know 2 is 0.

It isn't teleportation of the fucking particles are entangled. They are connected. That isn't teleportation that is travel.

>> No.3924412

>>3924404
you do know that quantum teleportation means the teleportation of information right? not of particles.

Ops here.. Thanx that was really helpfull. I know thats. I know that its as basic as it could be the thing you just explained but it made me understand.. Now another question. Isnt photon a wave/particle? And how can wave have a spin?

>> No.3924416

>>3924412
Information and particles are the same fucking thing on the Quantum level. They are waves and particles and can be either or at any time depending on observance.

Information == particles

A particle can have angular momentum, which in classical terms would be associated with its 'spin.'

There are a number of terms that carry over from classical models that don't exactly fit an intuitive explanation of QM, but they're well established, so we use them anyway.

My 8th grade science teacher on the first day of our physics curriculum came into the classroom and spun a large top on the floor. He told us 'Everything spins. Everything.....'

I had no clue what he was talking about ( he didn't elaborate much he just told us to keep it is mind for the future ) until I took quantum physics.

thank you for explaining the wave particle duality to me, eevn if it has absofuckinglutely nothing to do with what we are talking about.
