For the first time data has been teleported via quantum entanglement with a high degree of reliability.

The Journal of Nature Article
http://www.nature.com...

An overview in Science Daily
http://www.sciencedaily.com...

"The concept of entanglement was first formulated by Erwin Schr"dinger and involves a situation in which two quantum systems, such as two light particles for example, are in a joint state, so that their behavior is mutually dependent to a greater extent than is normally (classically) possible. In the Tokyo experiment, continuous entanglement was achieved by means of entangling many photons with many other photons. This meant that the complete amplitudes and phases of two light fields were quantum correlated. Previous experiments only had a single photon entangled with another single photon -- a less efficient solution."

Just think how fast the internet would be with this type of technology. Who would need wires?

On a serious note, it would not surprise me if down the road companies that are involved with algorithmic fast stock trading become sponsors to drive this technology.

They all currently house their servers right next to the exchange because they have to have a quicker response to trade in milliseconds before their competitor. Electrons moving through a wire is slow, so distance from the exchange matters.

Being able to transfer data via entanglement is instantaneous, so any application that is restricted by the speed of data transfer would greatly benefit.

The problem with that is how do you get information from your "quantum entanglement modem" to the stock exchange? Copper wire.

What is the closest you can get your "quantum entanglement modem" to the stock exchange servers? Right next to the exchange.

So you don't really buy yourself much.

Why would you use copper if you had a transmitter that sent data to a receiver instantaneous regardless of the distance? Granted that ability is a long way off, but they just did it a short distance with enough accuracy for computing.

At some point one would presume all receivers are made from this type of technology. Why would any one use old technology, when you can receive data instantaneously from anywhere in the world? In other terms you go straight to the exchange. As the technology is being adopted, yes a company could set up office in San Fran, send data without wires to their receiver next to the exchange. You wouldn't need an server like today which is extremely expensive right next to the exchange just a receiver.

So you don't really buy yourself much.

Straight to the exchange assumes the stock exchange leads the way and develops quantum receivers directly linked to their computers, but what is their incentive for such a costly, risky venture for no gain?

I am actually being argumentative for no reason. This is technology at best decades away and there is still no way to really speculate on how it might work, how large and expensive such devices might be, etc.

.....thus why I specifically said, "down the road" If the technology can be commercialized, that would be one industry that would push for it. Companies are already spending millions of dollars creating a daisy chain of microwave towers, because it is faster transmission of data than copper and optical fiber. It is an outright war.

I merely suggested they could become a driver of this technology because data speed is big money in the trading world. You are right there is no argument to be had here.

This is actually really interesting In the area of computer science. That being because there is research being put into using light for storing data. That being because, rather than simply have a binary system- 0's and 1's - you could use any light frequency. So, combining quantum entanglements of photons, with photons used as memory, would allow for instantaneous transmission of terabytes of data. Imagine, You could get every porn video online in less time than it takes to click the download button. It's seriously exciting.
