A Modular Quantum Compilation Framework for Distributed Quantum Computing

For most practical applications, quantum algorithms require large resources in terms of qubit number, much larger than those available with current NISQ processors. With the network and communication functionalities provided by Quantum Internet, Distributed Computing (DQC) is considered as a scalable approach for increasing number qubits computational tasks. DQC to be effective efficient, compiler must find best partitioning algorithm then perform smart remote operation scheduling optimize EPR pair consumption. At same time, should also local transformation each partition. In this paper we present modular compilation framework that takes into account both device constraints characteristics. We implemented tested based on proposed some circuits interest, such VQE QFT ones, considering different topologies, processors characterized heavy-hexagon coupling maps. devised strategy can exploit TeleGate TeleData operations impact using either only TeleGates or both. The evaluation results show have positive consumed pairs, depending characteristic compiled circuit. Meanwhile, choosing more connected topology helps reduce layers dedicated operations.
