Reusable Libraries Bridging the Classical and Quantum Software Stacks

Abstract
The classical electronic structure and quantum computing communities have developed largely independent software ecosystems, resulting in duplicated effort, inconsistent problem representations, and a barrier to the rigorous classical benchmarking essential for credible quantum advantage claims. This fragmentation is particularly costly at the interface where chemical problems are translated into quantum algorithms, where both communities would benefit from shared, well-tested infrastructure. In this talk, I describe our approach within the QDK/Chemistry library to bridge these stacks through modular, reusable components that serve classical and quantum workflows from a common foundation. I highlight specific examples that lower the barrier for practicing quantum chemists to engage with quantum algorithms without sacrificing rigor. I conclude with open challenges in sustaining cross-community interoperability as both software stacks continue to evolve.
