How does two particles get entangled?

[the_pulp]

I mean, which is the operational mechanism? Is it deterministic? I mean, can I "grab" two particles and make them entangled or the process is random and I can only make a lot of them and filter only the ones that get entangled?

My idea is that, perhaps, by knowing how it happens in real life, I can get a better idea about why it happens or which is the interpretation that I prefer.

Thanks!

You make an entangles pair by getting them to interact in any way that mingles their wavefunction.
