Teleportation: SF or Fact

Could be old news, but found it some time ago, and decided to share. Some would find it interesting.
Small note: The article make extensive use of quantum mechanics.

  1. Source: China claims record in quantum cat state.
  2. Source: Quantum teleportation achieved over 16 km.

And, the reference to the article itself:
3. Quantum entanglement and quantum nonlocality for N-photon entangled states.

Regards.

Holy cats

I’m buying a teleporter if it’s coming. That’s all.

It’s not really teleportation. If it comes into practical use, it’ll be for communication and not for teleporting things.

problem: you can only teleport 1 particle at once

Could it be used as binary code in the far future?

Program humans in binary code: Lots of work.

This is pretty much it. This is not teleportation in the classic sense, but rather two objects are “entangled”, and will always instantly match up with the other, so you’re kinda “teleporting” . . . physics or some silly thing like that. It’d be more useful for data transmission since you wouldn’t have to broadcast anything through radiant energy or conducted through wire, but rather by manipulating a particle that’s entangled with another, near-instant data transmission.

Also, humans could very well be written in binary, in many different ways, depending on what you wanted to accomplish.
If you were doing byte stuffing, i.e. just trying to cram all our data into as small a string of computer language as possible, a human would be around 800MB, not including any data required to HANDLE the human blueprints.

If you actually want to simulate the code’s function with efficiency and accuracy, or save space, you’ll need to add extra information for indexing, shorthand data representing unnecessary repetition, and even MORE code before it all to actually guide the functions. Or, you could recreate the relative function of the actual genetic machinery, but that would probably take EVEN MORE time, since you’d have to design very complex molecular simulations to account for all the big and little details that happen while all the countless different parts and scraps and machines work on, with, and around the DNA.

it’s either you’re really well educated or you stole that from Wikipedia :stuck_out_tongue:

I referenced wikipedia to confirm that 8 bits to the byte was still the standard among computers, but I don’t think that really qualifies as “stealing”.

I want it to be fact.

I mean, consider our DNA. It’s basically two chains attached, each a chain of nucleotides that pair up with the other half. Guanine–Cytosine, Adenine–Thymine, you’ve all probably seen it shown as a sequence of the letters G,T,A, and C. Really, just one strand contains the whole code, but the other exists for verification (like in error-correcting), stability, and a template during replication.

Since the whole thing is spelled out using only 4 different characters, you only need to count to 4 in binary, so just 00, 01, 10, and 11, each nucleotide could be made to take up only 2 bits, each of those numbers being designated to a certain nucleotide.

If you’re just storing the raw nucleotide data, you can basically ignore any additional information to index any location, so you can pack the nucleotide data into bytes as tightly as possible. Bytes are 8 bits, so you can fit 4 2-bit nucleotides in each byte. 3.2 billion / 4 = X GB, or 0.8GB (800MB). Slightly too big for a CD.

Now, that’s just the smallest and easiest way to store the raw code for a human, and doesn’t really account for any of the code to DO anything with the data, or any of the extra stuff that actually goes on with a cell’s molecular machinery. In fact, even just making a program that goes through and just obeys all the codons sequentially and makes whatever the code says would most likely not actually create something that resembles what happens in us, since there’s a HELL of a lot more going on with genetic machinery than just reading and manufacturing amino acids.

There’s still protein markers, gene activation/deactivation and the different ways it happens, DNA folding, gene regulation, splicing, outside factors, and countless other things which we haven’t even BEGUN to discover that all significantly affect what is actually done with the DNA. This also assumes that the source DNA was perfect and didn’t have any weird little flaws like some dumb insertion that knocks a whole gene out of commission by causing a frame shift.

You may also be interested in saving storage space, and there’s ways to compress our genetic code quite a bit that nature just doesn’t do since it hasn’t come upon it. Hell, from what we’ve seen the bulk of our genetic material is garbage that doesn’t do anything, and we’ve evolved crazy complex systems to get rid of the trash and end up with just the clean code at the end. Weird phenomena in our DNA such as long stretches of a small repeating sequence (from what I hear the Y chromosome in humans is mostly this vast, meaningless palindrome of code) could easily be compressed, but that would also probably necessitate some kind of indexing so the computer wouldn’t have to skim along the whole code every time to just look for that one thing (then again, some of our cellular machinery is basically doing something like this).

It’s all very complicated and there’s still quite a lot that we don’t know.

Stay in school, kids.

What cat?

it’s possible, yeah. michio kaku did a whole show about it, but sometimes he lets what he likes get in the way of real science.

What cat?
/Yeah, I’ve just started Half Life 2. Amazing graphics. I wanna do Alyx. Right now I’m on the sewers.

just put that 800mb file into WinRAR and you can fit 2 people on a CD :stuck_out_tongue:

loll
now go look up what a nibble is

me chinese me play joke me transport quantum information over a free space distance of 16 km

technically changing matter into energy and energy back into matter is possible, but achieving the latter and applying it to transferring “stuff”, including living things, is something science hasn’t been able to do yet
