Abstract: The quantum PCP conjecture is one of the central open questions in quantum complexity theory. It asserts that calculating even a rough approximation to the ground energy of a local Hamiltonian is intractable even for quantum devices. The widely believed separation between the complexity classes NP and QMA
This thesis describes a line of research culminating in a proof of the NLTS conjecture, first presented by Anshu, Breuckmann, and Nirkhe. The construction is based on quantum error correction and the thesis elaborates on how error correction, local Hamiltonians, and low-depth quantum circuits are related.
