NIST Physicists Show Ion Pairs Perform Enhanced &#039;Spooky Action&#039;
susskind described entanglement in a bit different way than I&#x27;d heard - &quot;that entanglement allows one to know everything there is to know about a system of particles (the whole), while knowing nothing about it&#x27;s parts.&quot;<p>In the classical version of an information experiment, if i randomize placement of objects A and B into 2 boxes, and send one of those boxes to someone else - upon opening my box I instantly know whether the other box contains object A or B.  The Quantum Mechanical version of the above experiment is very similar, except there could be several different degreees of freedom to measure on upon opening my box (what angle of spin measure on, etc..)<p>So to me, that doesn&#x27;t suggest that something &quot;traveled&quot; to the other box, just like in the Classical version.<p>Rather, somehow I only &quot;knew&quot; the system at the beginning without knowing &quot;any of it&#x27;s parts&quot; (due to entanglement &amp; superposition).<p>Then, just observing a degree of freedom in one the parts finally reveals what the corresponding degree of freedom in the other part was.<p>This (intuitively) makes more sense to me than saying &quot;information traveled&quot; and &quot;action at a distance&quot;
