  The anti self-adjoint operators of imaginary coordinate and momentum,
together with the self-adjoint operators of real coordinate, momentum, energy
and time are used in construction of the quantum field theory in operator form.
This formalism, being free of many dubious mathematical situations
characteristic to the standard treatment of quantum fields, is applied in
formulation of the new gauge condition for electromagnetic field that describes
the absence of the scalar and longitudinal photons. Proposed formalism offers
adequate theoretical framework for proper description of the multicomponent
fields, including quantum gravity.
