Science in Sci-Fi – Quantum Entanglement Communication

Science fiction is as the name suggests the fiction of science. I thought it would be a fun, interesting and at times mind bending idea too look at the science behind some of the technology in science fiction and look under the hood to see what’s required to make it work or what barriers are in the way.

Science in Sci-Fi – Quantum Entanglement Communication

First off – what is quantum entanglement? It’s where 2 sub atomic particles (were talking protons, neutrons, electrons etc here) become ‘linked’ in some way so that they both reflect the state of the other. This science is on the cutting edge of what we’re able to achieve.

This is science fact.

How does it work

If two ‘joined’ particles are separated by a long distance these 2 particles continue to reflect the state of the other. The interesting thing is that it seems to be that the change occurs instantly, regardless of distance. The Chinese have carried out experiments over hundreds or thousands of kilometres and proved that it works over this distance. What this might mean is that instant communication over long distances, like interplanetary or interstellar distances might be instantaneous.

This is at least how the Science Fiction world uses it. As always with Science Fiction the writers are trying to overcome the technical obstacles of now for their stories as the future needs to be better than it is now.

The idea of fast or instantaneous communication using something like quantum entanglement is something that would revolutionize space exploration – imagine being able to talk to Mars explorers in real time like on a telephone call on Earth. It’s exciting. The added advantage is that it’s totally unhackable, another linked particle to eavesdrop can’t be found.

What are the Challenges?

As with all these things are are challenges, most of which is the big unknown in this case and that is – How far can 2 particles be entangled for? Will they even reach the Moon? It would be a bit of an issue to create a radio for our future star travellers and they lose contact long before they reach the destination.

For now though, Sci-Fi thinkers and writers ignore the unknowns and carry on regardless. I don’t blame them – otherwise talking though space is a very long winded and boring conversation with most of it being the delay induced by boring light speed.

2001 – An Art Odyssey

Any of my long time bloggiesw ill know that one of my favourite all time SciFi stories is 2001 A Space Odyssey. For quite some time I’ve been thinking about what piece of work I could do for this. Eventually I chose this one, alshtough I have to say now that I would have done … Continue reading 2001 – An Art Odyssey

A Galaxy of Stars

A few weeks ago the sky was clearer than I’ve seen it for a long time and after seeing the success of someone else taking a picture with my same camrea I thought I would try the same settings and give it a go. The big variable with taking astrophotography pictures is the quality of … Continue reading A Galaxy of Stars

      1. In truth in that prescient quote from “Shape of Things to Come”
        “But for Man no rest and no ending. He must go on conquest beyond conquest. First this little planet with its winds and waves. And then all laws of mind and matter that restrain him. Then the planets about him. And at last out throughout cosmos beyond the stars And when he has conquered all the depths of space and the mysteries of time he will still only just be beginning.”

  1. You have a far more scientific mind than me Simon. Frankly, while certain aspects of science intrigue me, I can’t tell fact from fiction these days. Space exploration does fascinate me though! Have a great weekend. 😊
