I get quantum entanglement but I don't quite get how one would go about generating two complementary particles that are entangled (a photon and its entangled sibling, an electron and its entangled sibling, etc.).
Can anyone explain this referencing how this could be achieved in a lab?
Thanks!
For photons, the process that immediately comes to mind is Spontaneous Parametric Down Conversion where a single photon is split into two by a nonlinear crystal. I've never actually bothered to look up methods for other qubit systems, but it looks like a search for "generating entangled electrons" without quotes in Google Scholar turns up quite a few results.
