  A modular quantum architecture is given for the space-time, particles, and
fields of the Standard Model and General Relativity. It assumes a right-handed
neutrino, so that based on their multiplet structure all fundamental fermions
have isospin 1/2. This opens the possibility that the Higgs field can be
identified with the Yang $i$-field of 1947. The quantum gravitational metric
form proposed is a quantification of the Killing form of the quantum space-time
cell. There is no trace of the black hole phenomenon at the one-cell quantum
level.
