A major benchmark for near-term quantum computers is the demonstration of an advantage over their classical counterparts. This is a daunting task due to the imperfect nature of NISQ devices, but not all is lost. Recent light has been shed on provable, unconditional separations between the power of constant-depth quantum and classical circuits. These rest on the inability of shallow classical circuits to mimic non-local quantum correlations present in quantum games. In this regard, we leverage symmetry properties of graph states to design a family of quantum games with strategies that are robust to certain noise inherent to ion-trap computers making this an interesting application to test on a real device; namely the STAQ device, a surface trap-based quantum computer. To each game we attribute a Bell-type inequality whose violation witnesses the quantum advantage and study the robustness of the violation to noise.
