Sample-based Quantum Diagonalization (SQD) is a hybrid method for understanding how electrons behave inside molecules. It employs 'quantum-centric supercomputing' where a quantum computer explores the hardest part of the electron problem (the strongly interacting configurations) while classical supercomputers handle structure, correction, and refinement.
