  We derive the relativistic transformation laws for the annihilation operators
of the scalar field, the massive spin-1 vector field, the electromagnetic field
and the spinor field. The technique developed here involves straightforward
mathematical techniques based on fundamental quantum field theory, and is
applicable to the study of entanglement in arbitrary coordinate
transformations. In particular, it predicts particle creation for non-inertial
motion. Furthermore, we present a unified description of relativistic
transformations and multi-particle interferometry with bosons and fermions,
which encompasses linear optical quantum computing.
