I first came across a parallel with the concept of entanglement here: http://www.carlopescio.com/2010/11/notes-on-software-design-chapter-12.html where it is used as the term for all coupling, implicit or explicit. Physics has lots of useful metaphors (that do not work exactly in the same way) such as dampening to prevent a change rippling through, or centers of gravity for places that accrue more code over time.

Giorgio, I am a huge fan of metaphors in helping us understand and communicate abstract ideas.
But I also think that drawing parallels with physics (and especially quantum mechanics) is verging towards mysticism :-)
