How’s quantum teleportation work in this universe? Because that’s apparently a thing already.
That's quite the question to ask, but as far I can tell it only works with quantum information. Sending a body would be like you trying to fit into a fiber cable to be bounced inside of beneath the Atlantic to avoid the otherwise long flight.
From what I know of sci-fi, teleportation is often a machine that scans, destroys, and replicates the particles in your body at a secondary location.
So if we could figure out scanning and printing at the atomic scale, with zero defects, and pair it with sending information at near instant speeds via quantum teleportation, we could have a teleporter.
I think this is a bigger issue currently than sending large amounts of data across the globe. Though I wonder how much data a full copy would demand.
You just made me curious and we're not alone in wondering
https://slate.com/human-interest/2013/05/is-teleportation-possible.html
I was getting incredibly confused because the copy/paste didn't copy the superscript for the exponents. I was like, "there's definitely more than 1027 atoms in the body.. wait, how are there supposedly only 1021 bytes of storage in the whole world? Oooh.."
Ah, that would take a while to send 😁
Now I'm wondering how long it would realistically take for that to become a not-insane demand. I know data storage multiplies pretty rapidly, but not that rapidly, so are we talking decades or centuries?
Apparently we can already do it, a gram of dna can store 215 petabytes and we can encode to dna at 18Mbps.
Gonna be a long upload.
Quantum “teleportation” is not capable of sending information FTL. Quantum entanglement means that the wave functions of two or more particles (in essence, the information possessed by the particles) are correlated, but the information must be encoded by a device at the midpoint between the two observers and sent to the observers at a speed not exceeding the speed of light.
Teleportation in that term means “make a thing disappear in one place and appear in another”. No “immediate” is ever implied.
Wikipedia article has a great diagram on the topic. Add an article on “no cloning theorem” to understand why “teleportation” is a fitting term. I recommend reading both without expectation, just read through the steps as if you’re learning a new math tool.
In short, quantum teleportation is a way to take a quantum state (which are fundamentally unforgeable - you can’t simply create a clone of a particle), destroy it, extracting classically communicable data, and they recreate it in another location.
