Abstract: I shall briefly outline two complementary examples of probing the quantum origins of our universe. The first shall be a top-down approach in which I shall present a UV-complete model of early universe cosmology, starting from a non-perturbative (matrix) formulation of String Theory. In the second half, I will give bottom-up examples of where quantum entanglement becomes important in cosmology. In particular, I will show how an open quantum system approach reveals new (nonlocal and nonunitary) effects during inflation. Time permitting, I will illustrate more generally how quantum informatic measures, e.g. Complexity, plays a fundamental role in cosmic ER=EPR in dS holography.
