Low-depth Clifford circuits approximately solve MaxCut

MH Muñoz-Arias, S Kourtis, A Blais - Physical Review Research, 2024 - APS
We introduce a quantum-inspired approximation algorithm for MaxCut based on low-depth
Clifford circuits. We start by showing that the solution unitaries found by the adaptive …
