Consensus-based qubit configuration optimization for variational algorithms on neutral atom quantum systems.

ABSTRACT: We report an algorithm that is able to tailor qubit interactions for individual variational quantum algorithm problems. The algorithm leverages the unique ability of a neutral atom tweezer platform to realize arbitrary qubit position configurations. These configurations determine the degree of entanglement available to a variational quantum algorithm via the interatomic interactions. Good configurations will accelerate pulse optimization convergence and help mitigate barren plateaus. As gradient-based approaches are ineffective for position optimization due to the divergent R ^-6 nature of Rydberg interactions, we opt to use a consensus-based algorithm. By sampling configuration space instead of using gradient information, the consensus-based algorithm is able to su
