Entanglement

I’m not gonna dance for you
I know that you want me to
Better to dance alone
Than to dance with a ghost
I’m not gonna dance for you
Not like I used to.

Phase entanglement: “The entanglement of two interacting physical systems means that once the entangling interaction has occurred, the systems, even after eventual separation, can no longer be described as before, that is, as strictly separately independent states.” ~ Salvator Cannavo from Quantum Theory: A Philosopher’s Overview (2009)
