Discussion Overview

The discussion revolves around the concept of a theoretical instantaneous communicator using quantum entanglement, particularly focusing on the idea of entangling uranium atoms and utilizing their radioactive decay properties to transmit information. The scope includes theoretical implications of quantum mechanics and potential applications in communication technology.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant proposes the idea of using entangled uranium atoms to create a quantum communicator that transmits binary information through induced time dilation effects on radioactive decay.
  • Another participant cautions against taking mainstream articles on quantum mechanics too literally, emphasizing that entanglement is lost upon observation of one of the particles.
  • A subsequent reply clarifies that the proposed method involves observing radioactive decay rather than directly observing the entangled state, raising questions about the classification of such observation.
  • Another participant argues that while there may be potential for sending weak information through quantum mechanics, current research indicates that significant breakthroughs are still incremental and not ready for practical instantaneous communication.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility and implications of using quantum entanglement for communication. There is no consensus on the validity of the proposed method or the extent to which current research supports the idea of instantaneous communication.

Contextual Notes

Participants highlight limitations in understanding quantum mechanics as presented in popular media, and there are unresolved questions regarding the nature of observation in quantum systems and the current state of research on quantum communication.

I just saw this article on cnn: http://lightyears.blogs.cnn.com/2011/12/07/diamonds-entangled-in-physics-feat/

very interesting stuff, and it basically says that whole elements can be entangled with each other. It got me thinking about a possible quantum communicator to transmit zeroes and ones. For example, what if you were to entangle two uranium atoms with each other? I'm thinking that since the atoms would have identical vibrations, the radioactive decay timing would also be identical. By moving a dense object further and closer to these uranium atoms, you could induce a gravity field to create a slight time dilation effect, and thus impact the rate at which radioactive particles decay. the differences in timing could then be interpreted as zeroes and ones. I don't know if this is stupid or not, but let me know and explain why. Thank you.

Don't take what the article is saying too literally. Entanglement cannot persist after observations have been made. Once you observe one of the pairs of the entangled particles, the entanglement is gone. It's not like in the movies where the two atoms mimic each other across vast distances.
 
I realize that, buy you're not observing the entangled particle directly in this situation. Instead you would be observing the radioactive decay. I don't know if that classifies as viewing the entangled state though.
 
Main stream news articles that deal with complex matters such as quantum mechanics generally don't get the whole picture. While it may be possible to "sort of" send very small information information that has to be inferred from some complex mechanism with experimental break thoughts, any information that could possibly be sent at this point in our research would have to be very weak and definitely is not ready for something as big as instantaneous communicators, even though many scientists are working on it even right now.

By experimenting there are different ways to get indirect measurements http://physicsworld.com/cws/article/news/48126

But it's not like some giant break through that revolutionizes everything, all the things we're improving on in quantum mechanics are very small steps.
