The idea of quantum teleportation was first published in 1993 year. For a long time it was only a dream, scifi-like thing. Teleportation? Heh, this is in movies not in real.

"quantum teleportation has been realized in various physical systems. Presently, the record distance for quantum teleportation is 143 km (89 mi) with photons and 21 m with material systems." (Wikipedia).

But the experiments looks like this: one milion of photons are teleporting to another location, but only 1-2 are succesfully moved into it's destination. For a long time it was impossible to teleport data with less then 99,9999% loss rate. Till...

29 may 2014 – Scientists have transferred data by quantum teleportation over a distance of 10 feet with a ZERO percent error rate.

About speed of light:
As we know the speed of light in vaacum is near 300.000 km per second. Isn't possible to travel faster then light. But new discoveries and experiments proved that isn't true. Near one week ago (23 Jan 2015) scientists did something unbelivable!

23 January 2015 – Scientists have slowed the speed of light by using a special mask to change the shape of photons.

These photons after returning back to the vaacum didn't traveled with the same speed!
So, light doesn't have constant max speed. This discovery can change lots in the science. If is possible to slow down the speed of light, maybe it's possible to increase it too? Who knows...

By increasing the speed of light maybe we will be able to increase the speed of photons in Optical Fiber Cables. But this still isn't Quantum Internet. Quantum Teleportation is something much different.

Particle Entanglement:

Information send via QT reaches it's destination immedietly. Doesn't matter how far it travels. Even Einstein didn't explained how it works. We still don't know how. But experiments proved that's true. Two particles entangled together communicates between with one another immedietly! Distance has no matter here.

Try to imagine Network what is using a quantum teleportation. New speedtests avatars with ∞ b/s and "always 0 ping" are already done btw. Hehehe.

OMFG! This is amazing, I swear sometimes I become so enveloped in my computer and my passions I lose communication with the outside world even though I am on the internet.... LOL! Thank you for showing me this... TIME TO SPREAD THE WORD!

Try to imagine Network what is using a quantum teleportation. The scientists are working on this to make it available in next 5-10 years. New speedtests avatars with ∞b/s are already done btw.

I suggest you read the first paragraph of the Wikipedia page you linked and have at least a simple understanding of how quantum entanglement works before making assumptions like these.

If you imagine 0 latency and infinite bandwidth you are mistaken. Quantum teleportation based on what is presented here does not allow this because they still rely on classic communication methods that are limited by the speed of light. Also its worth noting that although its called "teleportation" its not really teleportation like in the movies. When two particles are entangled they share quantum states; they can be light years(measure of distance, not time) away but they will still mirror each other. This is what Einstein called "spooky action at a distance".

Also, "to make it available in the the next 5-10 years" does not mean that you will be able to have this on your computer in that time frame. It means that there may be a viable way that does not involve millions of dollars worth of equipment and a team of 100 specialists working to transmit single qubit of information.

If you have evidence that claims otherwise please let me know.

You should read more about theoretical possibilities of quantum internet and computers.

@dominique120 this technology will be available in next 5-10 years, so you can or no belive that. Don't care. But the commercial version of that technology will be not available in less then 25+ years.

You should read more about actual physics? Quantum teleportation is not FTL travel.

There is no such thing as Faster than Light Travel, the closer you get to the speed of light, time slows down, and AT the speed of light, time stops. If you exceed the speed of light, you start going backwards in time.

It's called
Time dilation
 
About speed of light and about actual internet's cables:
One of the fastest cables commonly used to transfer data in commercial networks is Optical Fiber Cable. The maximum speed which photons are traveling in it is less then 60% of Speed Of Light and capacity (max?) of 2.56 Tb/s(international submarine cable network).
Quantum Teleportation can increase those values to ~80% of Speed of Light and capacity to, and now will be suprice, to over xxx petabits/s.
Where 1 petabit = 10^15 bits = 1 000 000 000 000 000 bits = 1000 terabits.

Where do you get your information?
Fiber Optic Cables can transfer at 1 Petabit and it has already been done in Japan and demonstrated over a distance of 50 kilometers.

You cannot just research 1 site, or take the word of one person as truth. Singular humans are faulty and bad scientists, it takes peer review and multiple tests done by multiple people before something can be taken as fact.

Fiber optic cables don't work with electrons, they work with photons(light).

I'm quite aware of that. Actually YOU (Who would be getting close to c) would not sense time going slow. Remember there's two sides:
Bob: Travelling -> Experience Lenght Contraction (As far as I'm aware, I'm NOT moving)
Alice: Observing -> Experience Time Dilation Effect. (On YOU!)

And since everything's relative, it also works interchangeably

No? Where the heck did I say that?
I'm just saying that quantum tp is dependant on classical communication. Thought you were implying qtp to be FTL.

You are right, and I knew that. Don't know why I did that mistake in my post.

I'm not researching one site, in most situations I'm trying to get informations from the source which in this situation is very hard.
Many scientists independent to each other did a calculation how much capacity of QTp network can be (in theory). Even on polytechnic school near my city (in my country is equivalent to USA College(?), it requires atleast 1+6+3+4 years of studying to go there, and it lasts for 5 years. Total of 19 years of studying) was an home work -do an calculation of possible cap of QTp. Everyone had different result but proffessors said all of those values can be true, becouse it depends on many different things. Aslo he said: if japanese scientists can transfer data through cables with that fast speed, then QTp can be atleast 1 to 100 times much more capable.

I am not a student at this school, but often I'm there a free listener. It's good to tell to someone about QTp becouse I, you and anyother who readed something probably will start searching web about it. I did that. Checked over 20 sites and I found some interesting things which may not be about QTp. But this is one of the way to learn. Anyway I'm not thinking this what I'm reading is a fact, but I'm think "there is something interesting, lets find the source and let's know the truth".

Hurray for Science.

The fact of the internet is, Most companies lay MUCH MORE fiber cable than they need, and turn most of it off, then try to sell "Dedicated Fiber Bandwidth" to other companies.

I wonder how fast the internet would be if everyone would just turn everything up to the maximum. (Just using the current hardware in place)
