  I present and defend a new ontology for quantum theories (or
``interpretations'' of quantum theory) called Generative Quantum Theory (GQT).
GQT postulates different sets of features, and the combination of these
different features can help generate different quantum theories. Furthermore,
this ontology makes quantum indeterminacy and determinacy play an important
explanatory role in accounting for when quantum systems whose values of their
properties are indeterminate become determinate. The process via which
determinate values arise varies between the different quantum theories.
Moreover, quantum states represent quantum properties and structures that give
rise to determinacy, and each quantum theory specifies a structure with certain
features. I will focus on the following quantum theories: GRW, the Many-Worlds
Interpretation, single-world relationalist theories such as Relational Quantum
Mechanics, Bohmian Mechanics, hybrid classical-quantum theories, and
Environmental Determinacy-based (EnD) Quantum Theory. I will argue that GQT
should be taken seriously because it provides a series of important benefits
that current widely discussed ontologies lack, namely, wave function realism
and primitive ontology, without some of their costs. For instance, it helps
generate quantum theories that are compatible with relativistic causality, such
as EnD Quantum Theory. Also, GQT has the benefit of providing new ways to
compare and evaluate quantum theories, which may lead to philosophical and
scientific progress.
