Q-Score

Q-Score is a quantum computing benchmark metric developed by Atos that evaluates quantum processors using QAOA applied to the MaxCut problem. It provides a standardized, hardware-agnostic way to compare quantum computing platforms. Q-Score measures the maximum number of variables in a MaxCut problem that can be solved with acceptable quality.[1]
