Stephen DiAdamo (Qoro Quantum): Middleware that hides QPUs, GPUs, and CPUs behind 20 lines of code

Stephen DiAdamo, co-founder and CTO of Qoro Quantum, is interviewed by Yuval Boger. DiAdamo discusses Qoro’s position as a software middleware company that abstracts hardware away from applications, walking through the Divi SDK, circuit serialization and parallelization, and an orchestrator that automatically selects between 12 simulation methods on CPU and GPU or dispatches to QPUs from any vendor. They explore how Qoro plugs into HPC schedulers like SLURM rather than replacing them, the CESGA proof of concept built on the CUNQA platform, the “150,000 lines of code to 20” claim, and the argument that multi-QPU centers are needed today for fallback and resilience and for scaling applications. DiAdamo also reflects on developer experience for students learning QAOA and variational algorithms, and Qoro’s two-year history.

Key takeaways

• Qoro’s Divi SDK takes optimization inputs (QUBO, HUBO, variational algorithms) and automatically generates, serializes, and parallelizes thousands of quantum circuits without the user writing transpilation or scheduling code

• Their orchestrator picks among 12 CPU/GPU simulation methods (stabilizer, tensor network, Pauli propagation, MPS, etc.) or routes to QPUs from any vendor, choosing based on circuit properties rather than user input

• Qoro relies entirely on hardware vendors’ own transpilers rather than building their own, acting as an automation and routing layer rather than solving the hardware-specific compilation problem

• Multi-QPU access is a resilience requirement today, not a future scaling need: when an HPC center’s only quantum computer goes down (as happened with an IBM outage), users have no fallback unless multiple vendors and modalities are integrated

• In a CESGA pilot using the CUNQA platform, Qoro connected to 15 compute nodes mimicking a distributed quantum network and ran 15,000-20,000 circuits remotely, with the secure integration taking about a day to wire up
