Einstein's brilliant mistake: Entangled states - Chad Orzel
View full lesson: http://ed.ted.com/lessons/einstein-s-brilliant-mistake-entangled-states-chad-orzel When you think about Einstein and physics, E=mc^2 is probably the first thing that comes...
==========
Albert Einstein played a key role in launching quantum mechanics through his theory of the photoelectric effect but remained deeply bothered by its philosophical implications. And though most of us still remember him for deriving E=MC^2, his last great contribution to physics was actually a 1935 paper, coauthored with his young colleagues Boris Podolsky and Nathan Rosen. Regarded as an odd philosophical footnote well into the 1980s, this EPR paper has recently become central to a new understanding of quantum physics, with its description of a strange phenomenon now known as entangled states. The paper begins by considering a source that spits out pairs of particles, each with two measurable properties. Each of these measurements has two possible results ...
