Entanglement in QFT?

    All definitions of entanglement, that I have encountered, were expressed in the language of non-relativistic QM.

    Suppose a free, massive particle decays into 2 other massive particles. The 2 new particles would be entangled in linear momentum. Can QFT define that type of entanglement? Any examples?

    Thanks in advance.
