Modular software stacks for quantum computing at scale

The path to scalable quantum computation is increasingly relying on advanced software tools to design, simulate, and run circuits on noisy quantum hardware for current-day NISQ applications and on long-term fault tolerant system development. Today the ecosystem consists of compilers and transpilers, circuit- and pulse-level program definition, and a multitude of domain-specific languages, often derived from full-stack solutions. ParTec AG approaches the software stack from the perspective of an HPC-QC systems integrator. In this talk, we will discuss the current challenges and opportunities in modular systems from the software side. We will review the state of play in the software domain at the different levels of the stack, with an emphasis on commercial development, modularity, and cross-QPU compatibility. Finally, we will present ParTec’s software at the quantum-HPC interface, QBridge, in the context of quantum computing solutions delivered via HPC clusters.
