Abstract:
A major challenge in quantum computing is scaling up quantum hardware: most commercially and industrially relevant problems require more qubits than a single quantum processing unit (QPU) can currently provide. Instead of attempting to fit more qubits into a single device—a process that is both technologically difficult and fundamentally constrained—Distributed Quantum Computing (DQC) leverages a network of near-term, mid-sized QPUs to emulate the capabilities of a large, monolithic quantum computer. By exploiting entanglement, a central resource in quantum mechanics, these interconnected QPUs can communicate and share quantum information. In this context, a DQC compiler is essential: it partitions large-scale algorithms and maps them across multiple coordinated QPUs, enabling the execution of computations previously beyond reach.

Short CV:
Riccardo Mengoni completed his master's degree in theoretical physics at the University of Camerino with a thesis on Quantum Computing (QC). He proceeded to pursue his PhD at the University of Verona, where he worked on Quantum Machine Learning (QML). In the summer of 2018, he was selected for the USRA Quantum Academy that gave him the opportunity to be a NASA intern focusing on quantum annealing applications. Following this experience, Riccardo joined the CINECA High Performance Computing (HPC) center as a Quantum Computing researcher, dedicated to exploring the integration of QC and HPC. Currently, Riccardo is a Quantum Algorithm researcher at Welinq, focusing on Distributed Quantum Computing (DQC).
