The quest for a unified field theory began in 1928 with Einstein’s vierbein field theory of gravity and electromagnetism. Although Einstein’s approach was not accepted at the time, today it is foundational to studies of quantum gravity. Presented is a study of quantum gravity using a quantum mechanical generalization of Einstein’s vierbein field-based approach. Here the quest
for unification is limited by finding an appropriate quantum lattice model that captures the physics of the Lambda-CDM model and the Standard Model. Such a model constrains the physics beyond the Standard Model and General Relativity by preserving the basic theoretical frameworks of these quantum and classical theories (with necessary but minimal additions to each). The quantum gravity theory presented here derives from first-principles associated with quantum information dynamics intrinsic to quantized space, which is taken to be a tensor product space on a qubit array. So the quantum gravity theory, when cast as a quantum lattice model, becomes a quantum computational representation of the unitary dynamics and mutual interactions of particles, gauge fields and curved space. Its applications to high energy physics and cosmology are intended to apply future scalable quantum computer technology (when this technology becomes available) to efficient quantum simulations of nonperturbative quantum dynamics (i.e. lattice QCD as well as computational GR near the Planck scale). Yet, the aim of today’s talk is to introduce the quantum gravity theory and present an analytical calculation that puts a lower bound on the mass of the Higgs boson.
