Non-Isometric Codes, Complexity, and the Black Hole Information Paradox

Abstract: This talk focuses on recent progress on the role of computational complexity in the black hole information paradox. I will describe quantum code models that settle the tension between two conflicting calculations of the entropy of Hawking radiation within semiclassical gravity: the standard “Hawking” calculation and the quantum extremal surface calculation. The critical aspect of the construction involves a complexity bound on the validity of effective field theory, and I will discuss applications of this from the geometric perspective of holography as well as computationally bounded quantum learning.
