Traditional LSQC studies primarily focus on optimizing for reduced circuit depth by adopting a device-centric design methodology. However, these approaches overlook the impact of classical processing and communication time, thereby being insufficient for Dynamic Quantum Circuits (DQC). To address this, we introduce CLASS, a controller-centric layout synthesizer designed to reduce inter-controller communication latency in a distributed control system. It consists of a two-stage framework featuring a hypergraph-based modeling and a heuristic-based graph partitioning algorithm. Evaluations demonstrate that CLASS effectively reduces communication latency by up to 100% with only a 2.10% average increase in the number of additional operations.","short_abstract":"Layout Synthesis for Quantum Computing (LSQC) is a critical component of quantum design tools.
