E T Call Home


Let me start by saying that the SETI program (Search for Extra Terrestrial Intelligence) is a total waste of valuable time and resources. It doesn’t matter whether you believe that aliens (if they do exist) come from deep space or another plane of existence. Either way they are going to need a means of communication that works better than radio waves. For communication between the stars ordinary radio waves, which are subject to the same speed limit as light, simply will not do. The nearest star is several light years away. That means that radio or laser based communications would take several years to send a message just one way and double that for an answer. If you believe that the little green men live in an alternate dimension or universe then even if they do use radio waves for communication in their own domain they cannot communicate between dimensions or parallel universes by that method or we would be swamped with their transmissions.


So how do they communicate you ask? And I do have an answer. It might not be the right one but it is one possibility. I propose that they use entangled photons.


Follow this reasoning…

We can send both amplitude (AM) and frequency (FM) modulated signals by radio waves so why can’t we at least send FM signals by entangled photons. I am not sure we could modulate the amplitude of photon entanglement but FM should work just fine once we fully develop the technology. After all we didn’t have the ability to send even simple AM signals when we first invented the telegraph now we have cheap wireless home telephone handsets that operate in the gigahertz frequency range. All we need to do is develop a way to gather a large number of entangled photons and modulate the state change fast enough to simulate a carrier wave like we use in radio. Then we would need a way to detect that modulation and convert it to information. It is probably a daunting task to say the least but that is what was thought of radio before we perfected it.


What are some of the advantages, besides eavesdropping on ET, of such a communication system?


Because it would be instantaneous it would allow real time control of lunar and mars probes. Instead of them being autonomous and on their own for decision making they could be controlled in real time with just a keyboard and a joystick. No more letting them just wander around and get into trouble before an operator could intervene.


But an even more important application would be to place satellites as close to the sun as possible and let them monitor flares and coronal mass ejections. The instantaneous nature of the data received would give us a longer lead time to protect our communications satellites and any astronauts in space.


I doubt that we have the technology right now to accomplish this but the benefits of instant communications from any distance should make it a priority area of study. So what if we have to start off sending Morse code again. We have some brilliant physicists who should be able to find a way to make advances in the new technology just like they did with the old technology we use right now.

They are coming closer to the method  described in the OP.

  • By destroying light in one place and recreating it remotely in another place, researchers have found a way to teleport light.
  • This development might be used to design faster quantum computers.
  • Like the classic example of Schrödinger's cat, these entangled packets of light were paradoxically "dead" and "alive" at the same time.

Experimental quantum teleportation experiments were conducted on a machine known as "the teleporter" in the laboratory of Professor Akira Furusawa in the Department of Applied Physics in the University of Tokyo. Click to enlarge this image.

Researchers from Australia and Japan have successfully teleported wave packets of light, potentially revolutionizing quantum communications and computing.

The team, led by researchers at the University of Tokyo, say this is the first-ever teleportation, or transfer, of a particular complex set of quantum information from one point to another.

They say it will make possible high-speed, high-fidelity transmission of large volumes of information, such as quantum encryption keys, via communications networks.

The research appears today in the journal Science.

Professor Elanor Huntington, of the School of Engineering and Information Technology at UNSW's Canberra campus, explains that teleportation -- the transfer of quantum information from one location to another using normal, "classical" communications -- is a fundamental quantum communication technique.

"It relies on having two things," she said.

"One is the normal fiber optic internet or even copper cables, and the other is a shared resource between the sender and the receiver, that could have been shared at any time in the past: we call that entanglement."
