Molecules were held in a state of quantum superposition

Click For Summary

Discussion Overview

The discussion centers around the concept of quantum superposition as it applies to atoms and molecules, exploring whether more complex structures can also exist in such states. Participants reference experiments and theoretical implications related to observation and decoherence.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants note that entire atoms and molecules have been observed in quantum superposition, questioning the implications for more complex structures.
  • One participant introduces the concept of decoherence, suggesting it explains why many-particle systems do not exhibit quantum behavior due to rapid wavefunction collapse.
  • A participant raises a question about the definition of observation, discussing different interpretations and referencing an experiment involving lasers related to superposition.
  • Another participant expresses interest in the topic and seeks additional resources, indicating prior discussions with a physics professor about the possibility of superposition in complex structures.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the implications of quantum superposition for complex structures, and there are differing views on the nature of observation and its role in quantum mechanics.

Contextual Notes

Discussions involve assumptions about the definitions of observation and the conditions under which superposition can be maintained, as well as the effects of decoherence on quantum systems.

I have read about experiments where entire atoms and even whole molecules were held in a state of quantum superposition. It wasn't until an observation was made that these molecules left their indeterminate state. If whole atoms and molecules can exist in quantum superposition, does theory prohibit even more complex structures of matter from existing in a superposition as well?

As in the other thread this is a sticky subject, but one with a much clearer answer -decoherence, which shows that statiscally why many particle systems do not exhibit quantum behaviour due to the fact that there wavefunctions collapse very quickly.
 
Yes but one must ask...What is defined as observation? is it when a random wave or electron bumps into the object in question? An experiment performed by a man I believe in India, but please forgive me if I am worng, but he found a way to test for super position by using lasers and inialation (<---sp?), its very good, and I believe you can search under Hardings paradox, or soloution to...

Do you have some links about this? Well, I'm very interested in this subject, because long time ago I've discussed with one physics prof. about possibility of that kind superposition, and if you\re righ, I was right :)
