Any developments in Quantum communication?
I have a hunch that we are using the wrong technology to look in the
wrong place, and consequently, am not very confident of SETI ever finding anything - after all these years of trying so hard. We have tried so hard and don't appear to be making much progress and it's like everyone is saying "can't stop now, we've come this far, we can't really stop now to check whether we are on the correct path". I think the whole SETI project needs a serious rethink (IMHO). How come we have not detected any significant messages after all this time?. I know it is a hard problem to solve, but "failure" after so many years should surely cause one to stop and check if what we are doing can ever achieve the results we "know instinctively" of but have no prove of (yet). Most scientist agree that the odds of life forming out there in the universe is very high. It is not inconceivable then, to postulate that since some parts of the universe/galaxy are billions of years older than our solar system, it is probable that sentient life has developed somewhere else. I believe we can once again turn to nature and see how "she" does things. A lot of communication in nature is done via so called "energy perbutations". From a scientific point of view, the only framework we have (so far) for explaining instantaneous, simultaneous communication is Quantum Mechanics and Quantum Communication. However, we don't seem to hear much about development in this field (or am I just not aware?). Does anyone know of research or developments being done in this area? As an aside, I am considering funding research in this kind of work - since I don't think we can (or for that matter should) depend on governments and politicians to be the main players in answering the fundamental question of "are we alone?". I will be very interested in getting an open source project started, to further R&D in quantum communication software and quantum devices. Look forward to your response |

We have only made an extremely brief look. We are using only meagre resources for our search. There is a vast amount of searching yet to do. [...] perbutations".

The old quantum "spooky communication at a distance"?... I think there is a lot more theory work required! However, we don't seem to hear much about development in this field (or am I just not aware?). Does anyone know of research or developments being done in this area? Try Google... There is a lot more there than what I can read!

Please keep us posted. Good luck, Martin -- ---------- OS?

There really hasn't been that much searching at significant sensitivity or covering much of the spectrum. It is far too early to be discouraged. We have tried so hard and don't appear to be making much progress and it's like everyone is saying "can't stop now, we've come this far, we can't really stop now to check whether we are on the correct path". I think the whole SETI project needs a serious rethink (IMHO). The SETI Institute convened a series of workshops of outside experts to consider new approaches. The workshop concluded the current approaches were still valid, but recommended some new areas for research. New optical searches and a new telescope design came out of those workshops. The results are published in a book "SETI 2020". How come we have not detected any significant messages after all this time?. I know it is a hard problem to solve, I don't think you really appreciate just how hard the problem is, or how little searching has been done. Phoenix and SERENDIP are the only projects to achieve good sensitivity and frequency coverage. (SETI@Home only covers about 2 MHz.) Project Phoenix just finished in March and over a span of nine years covered the equivalent of 800 stars over the available frequencies between 1.2 and 3.0 GHz. That's hardly a statistically significant sample of the stars in our galaxy. I believe we can once again turn to nature and see how "she" does things. A lot of communication in nature is done via so called "energy perbutations". From a scientific point of view, the only framework we have (so far) for explaining instantaneous, simultaneous communication is Quantum Mechanics and Quantum Communication. Quantum entanglement still requires two particles and to use them to communicate two widely separated points, the particles have to be moved to those points. If the ETs in the Alpha Centauri system were to send us a particle connected to one in their laboratory, how would we recognize it? Perhaps they would send a radio message with instructions. :-) As an aside, I am considering funding research in this kind of work - since I don't think we can (or for that matter should) depend on governments and politicians to be the main players in answering the fundamental question of "are we alone?". All SETI programs are privately funded. NASA is funding some workshops to consider the possibility of life on planets orbiting low mass (M) stars. Besides the implications for astrobiology, the results of these workshops will be used to add stars to a SETI target list for the Allen Telescope Array. That is the only US government money that helps SETI in any way. I will be very interested in getting an open source project started, to further R&D in quantum communication software and quantum devices. Good luck. Peter Backus Project Phoenix SETI Institute |
