We present unitarily represented supersymmetric canonical commutation
relations which are subsequently used to canonically quantize massive and
massless chiral,antichiral and vector fields. The massless fields, especially
the vector one, show new facets which do not appear in the non superymmetric
case. Our tool is the supersymmetric positivity induced by the Hilbert-Krein
structure of the superspace.Comment: 14 page
