Fast MAXCUT, TSP, and sampling heuristics from near-ideal transverse field Ising model (TFIM)

Here we will compare one well-known (ED) and another new method (QAOA) for quantum simulations of many-body physics.

Qiskit VQE for detecting quantum phase transitions in the Axial Next Nearest Neighbor Ising (ANNNI) model reproducing Lively et al. (2024) with noisy-simulator .

Mechanistic interpretability of classical neural networks trained on quantum data — using sparse autoencoders to detect quantum structure in classical representations.
