  In this paper we present a multipartite formulation of gauge theory gravity
based on the formalism of space-time algebra for gravitation developed by
Lasenby and Doran (Lasenby, A. N., Doran, C. J. L, and Gull, S.F.: Gravity,
gauge theories and geometric algebra. Phil. Trans. R. Soc. Lond. A, 582,
356:487 (1998)). We associate the gauge fields with description of fermionic
and bosonic states using the generalized graded tensor product. Einstein's
equations are deduced from the graded projections and an algebraic Hopf-like
structure naturally emerges from formalism. A connection with the theory of the
quantum information is performed through the minimal left ideals and entangled
qubits are derived. In addition applications to black holes physics and
standard model are outlined.
