That class is NOT small because something is always entangled with something; you should look at the "Wigner's Friend" thought experiment. When I open the box I become entangled with Schrodinger's Cat and know if it is alive or dead (Everett would say I now know it is alive AND dead) but you are in another room behind a closed door so you are not entangled with me and still don’t know what the cat’s fate is. When you open the door and hear me report on the status of the cat you become entangled with me and because I’m entangled with the cat now so are you. >* * > *In the experiment described in your link, the interference effect of the > superposition required cooling the object to nearly absolute zero, 0.5 deg > K.* > Making things cold decreases the ability of objects to become entangled it does not increase it. At room temperature so many things become entangled from so many different pathways and they do it so quickly that experiments become impractical. The colder things get the more control you have and the easier it is to figure out what’s going on. For the experimenter the hard part is not getting things to become entangled but to reduce the number of entanglements to a reasonable number so it can be studied. > ** > *We need to carefully revisit the issue of superposition and what it > implies for quantum effects to be manifested, before we can conclude > anything firm about the experiment you cite.* > Physicists have been thinking about this for 90 years and there is still no consensus, the only thing they agree on is there is no quantum interpretation that is consistent with both the experimental facts and our intuitive feeling about everyday reality. Something weird is definitely going on. John K Clark -- You received this message because you are subscribed to the Google Groups "Everything List" group.
