This is one of those things that needs to happen for "the future" to happen. Like a fusion plant that powers the entire Earth wirelessly. That way nothing would ever need to be charged ever again, and from there we get to flying cars and massively powerful small devices.

Once again a powerful enough computer could easily fix this. The computer would read each individual atom before transport and each individual atom during, then all the atoms would be arranged back in the order they were before being ripped apart/converted to energy.
Yes and it could "beam" you through spacetime. And we could call them "transporters"!

The one thing Star Trek got right was if we get teleporters and replicators money would become worthless and greed would become irrelevant.

Still makes you think what happens to you during that process.

Energy still won't be infinite. Some kind of a credit system would be required to regulate it, with more credits allocated to bodies that would put it to better use than ordinary people.

You want to regulate the universe's energy?

I could just get one of those stationary bike generators and "make my own credits"

Not really, as we progress each of our houses will produce all the energy we need. There wont be electric companies regulating everything.

I think wave function collapse confuses people. An envelope always either has or doesn't have a prize. It's determined when someone puts it in the envelope. The spin, however, is determined upon being measured, for both particles at the same time - which obviously seems like some information is being teleported between the particles even though we cannot use it.
So you're saying that you can make n amount of measurements and the chance of the spin being positive or negative will be about 1/2n (50%). And that P1spin=P2spin at the time of measurement?

How do we know that a random variable isn't being produced at the time of entanglement? What makes this different than both particles following a function?

The universe explodes.

Should be a good enough incentive not to fuck up.

I don't know, but I think there's some reason why physicists would believe in magic like that

But the important question is this: can it bypass the lightspeed limit?

Nothing is different. They both follow the same wave function. That's why they are entangled.

Edited:

No. You still have to share the time of measurment between the "readers" .

That enables both readers to read the same information.

This technique is used to create uncrackable encryption.

The readers read the two particles at the same time or with a MINIMAL lag since changing the spin for example also takes some time. In the end they read the same information and use this as the key to encrypting data.


Now they can easily exchange the encrypted date and noone else can read it since only those two know the key.
The key is not crackable either since it's generated randomly from the quantum status of the two particles while reading.

It even goes further.

Let's say someone is between both and knows the exact time of the reading and reads an entangled 3rd particle.
The reading itself would also influence the other measurements and thus change the results. So you'll always see if someone tried to read your "time" after comparing the keys.

Could be fun to see a file corruption in the data the computer sends to the end point for the reconstruction sequence.

Loseless wireless electricity anyone?

The methods they are using now to teleport things aren't going to work, since I'm pretty sure quantum entanglement would kill any living thing. If it was even possible on something human's size.
Still, if they manage to teleport bigger objects it would be awesome for alot of stuff, imagine teleporting objects from one factory to another or from a factory directly to shops, cargo transportation would completely change.

Teleporting pizza deliveries.

Those kinds of diagrams always remind me of the numerous times I've tried and failed to understand the plot of Primer.
Never seen it, but I've heard it's confusing as all fuck. Like proper mind-fuck stuff.

They're putting energy into an entangled particle and taking it out of its counterpart at the other end. Does that mean that we could eventually do the same on a massive scale and transmit energy through entangled computer chips, thus directly connecting computers and enabling real-time communication across any distance?

God, I hope so.

The thing that bugs me about teleportation is this:
You could possibly copy the position of every atom and molecule of a person and replicate that somewhere else, but how do you replicate the momentum of the blood and various chemical transactions reliably? It's stuff like that that keeps us alive, after all.

Teleportation won't be what it reads as. It'll just recreate something, destroying the original. That could be deadly for us as it could possibly wipe your brain?

Yeah, copy. That's why if teleportation is ever invented in my lifetime (which won't) I'll never take one because of the fear of "me" dying and just a perfect copy being created on the other side.

Isn't calling this 'teleportation' an incredibly bad misnomer? Unless I'm rather mistaken, to entangle particles you require them to initially be in contact with one another and somehow get them to have some correlative state, such as one having positive spin and anther negative(for photons). You can then move them apart by any distance, but at this point their spins are completely unknown until you measure one, once you measure one and find its spin to be positive, you instantly know the other is negative, thus you can say that the other particle went from being of unknown spin to the opposite spin to the particle you have, yet the other particle hasn't physically changed in any way, you merely have more information about it due to deduction, right?

Not to mention that you can't force the spin to be anything thus you can't use this to transmit information faster than c so I don't see what's so amazing about this. It's like having 2 envelopes, one with a prize in and another that's empty, you can separate them by a lightyear and if you open one and find a prize, you'll know the other person has an empty envelope, but checking it doesn't really change anything, nor can the other person know if/when you've opened it so yea.
I have no idea what this guy is talking about, but he is right.
