  A simple quantum superfield generating equation of the field-antifield
formalism is proposed. The Schroedinger equation with the Hamiltonian having
$\Delta$-exact form is derived. An $Sp(2)$ symmetric extension to the main
construction, with specific features caused by the principal fact that all
basic equations become $Sp(2)$ vector-valued ones, is presented. A principal
role of quantum antibrackets in formulation of the Heisenberg equations of
motion is shown.
