TU Delft’s Entanglement Lab

Over the past week there has been quite a buzz in the scientific community over a Dutch experiment reliably transmitting data instantly between two electrons via quantum entanglement. While many reports are sensationalizing the discovery, referring to it as a breakthrough in ‘teleportation’, there’s something almost as exciting as physical transportation already proven possible in the experiment: instant communication! While scientists have reached a 3-meter(or 10-foot) range with a 100% success rate, worldwide implementation would revolutionize communication. Instant text messages, infinitely scalable internet bandwidth, and sub-millisecond(or even sub-measurable) latency. Even now, our fastest long-distance communication efforts are too slow to be pushed any further. NASA, one of the foremost names in high-tech, has to wait 13-minutes to remotely issue a command to the Curiosity rover.

So how does it work? In basic terms:

Since the data technically does not travel through physical matter to reach the receiver, there’s no inherent risk of natural effects on the transmission itself. Data transmission through quantum entanglement could usher in a new era of computing without fear of disruption or as much dependence on redundancy. Electronic hardware itself would be restructured from the ground up, less resistors, less heat, and less restrictions on bandwidth across the board. Concern for network growth in isolated areas might also soon be a thing of the past, if researchers manage to create a reliable way for global reach of the transmission, there wouldn’t even be a need for cable installation or cell towers!
The experiments are being conducted at the Delft University of Technology in the Western Netherlands and lead by a Professor Ronald Hanson. According to TU Delft’s news board, Hanson plans to repeat the experiment in the upcoming months, but with a new distance goal of 1.3km(0.8mi) to prove beyond a doubt that Einstein was wrong in his rejection of quantum entanglement.

I tried to share this, but my sub-space communicator is down.

Open a sub-space channel, Lieutenant Uhura.
Will this mean better Weismann scores?
Sorry, I still can’t get past that whole conservation of angular momentum thingy.
My interpretation of quantum entanglement is that we don’t really live in a 3-dimensional universe like the one we perceive. Dimensions and space are an illusion.
How do electrons get ‘entangled’, and how does one keep them that way?
Can they be divorced?
To put this discovery in “Star Trek” terms, it’s more like “sub-space transmission” than a teleporter. For you non-geeks, “sub-space transmission” was the ability to communicate with earth or another starship in real time, even though they might be thousands of light years apart.
A practical application of this in the micro scale would be to distribute the CPU clock across the chip. It reduces heat, decreases complexity of the chip, and would allow for many muliple clocks. This could account for a significant increase in CPU/chip/ASIC performance.
Wake me up when they can do something useful with this. At least 20 miles land based and globally via satellite. Or better yet, globally with no satellite.
Or better yet, time travel.
“Dimensions and space are an illusion.”
That, of course, begs the questions of “then what is not an illusion”, and “an illusion to whom or what”? But I don’t mean to hijack the thread.
It’s all an illusion, just like a video game.
The article is full of hype and empty of information. How do you entangle two atoms? How do you know which ones are entangled? How do you separate them after they are entangled? How much energy is used in the process? Observing a quantum state destroys it.
Any theory that states that a “cat” is both alive and dead in a box until someone opens the box, is a false theory. Where are the animal rights people protesting about cat abuse?
Or, energy in the local limit. I bang my knee and it hurts. Scale the energy up though, and I’d bet things get weird pretty fast.
Thanks for posting this. Fascinating (if not spooky) stuff.
