Science Daily reports that engineer Seth Lloyd has proposed using quantum mechanically entangled photons to develop detection systems that would be a million times more efficient than anything currently in existence. The quantum based photodection system would have widespread applications, from more efficient night-vision equipment to CT scanners that used lower levels of radiation.
For the more technically inclined, here is a paper by Lloyd and his colleagues on enhanced imaging utilizing quantum theory:
Just to note, this area of research was pioneered by Jonathan K. Dowling and others, who are not mentioned in the Science Daily article:
As an aside, here is a video of Seth Lloyd, talking about quantum computers, and interestingly their capacity (if one could be built) to surpass the capacity of a human brain. I am really interested in this point because I don't believe classical computers or current artificial intelligence (AI) can do this, no matter how advanced they become.
Something Lloyd says is "You don't have to understand the nature of things to build cool devices". OK, spoken like a true Geek. "Cool" devices are one thing, but personally, I am more interested in how the universe works and why it works the way it does rather than some engineering marvel. I want to understand the nature of reality like David Deutsch does.
