Problem Statement
The quantum computing industry faces fundamental barriers in software development and compilation that limit the transition from experimental research to practical commercial applications. Current quantum software development requires specialized expertise for each hardware platform, creating fragmented ecosystems that slow innovation and increase development costs for quantum applications. Quantum startups and researchers struggle with two critical challenges: access to top-tier quantum talent and access to quantum hardware for testing and validation. The quantum talent pool remains extremely limited, with fewer than 10,000 professionals worldwide and only tens of specialists in specific quantum computing sub-disciplines. Hardware access barriers prevent many promising quantum algorithms from being tested and optimized on real quantum systems, forcing researchers to rely on classical simulators that may not capture important hardware-specific effects. Existing quantum compilers are typically proprietary, hardware-specific, and lack the flexibility needed for hybrid quantum-classical applications that represent the most promising near-term quantum computing paradigm. The compilation process from high-level quantum algorithms to hardware-specific machine instructions often requires months of specialized development work, creating bottlenecks that delay quantum application deployment. Financial constraints limit many research institutions and startups from accessing premium quantum hardware and software development tools, creating unequal opportunities for quantum innovation. The lack of standardized compilation frameworks forces developers to recreate fundamental software infrastructure for each new quantum project, resulting in duplicated effort and slower progress across the quantum ecosystem. Industry fragmentation between different quantum hardware modalities including superconducting, trapped-ion, photonic, and neutral atom systems requires separate development efforts for each platform, multiplying software development costs and complexity.
Quantum Approach
The CODE project develops a comprehensive open-source compilation infrastructure centered on the Catalyst compiler, designed to bridge the gap between high-level quantum algorithm descriptions and hardware-specific implementations across multiple quantum computing platforms. Haiqu contributes advanced quantum middleware technology including circuit optimization, error mitigation, and subcircuit compression techniques that enable efficient execution of complex quantum algorithms on near-term hardware. The Catalyst compiler implements a hardware-agnostic approach that allows developers to write quantum programs once and deploy them across different quantum systems, similar to how traditional compilers enable software portability across classical computing architectures. Open Quantum Design provides the foundational trapped-ion quantum computer platform as a reference implementation and testing environment, offering full-stack access from hardware specifications to application programming interfaces. Xanadu integrates photonic quantum computing capabilities and cloud platform expertise, enabling the compiler to support both gate-based and continuous-variable quantum computing paradigms. The collaboration establishes an open-access development sandbox where global quantum researchers can contribute to compiler development, test new optimization techniques, and validate quantum algorithms on real hardware without proprietary restrictions. The project incorporates advanced compilation techniques including quantum circuit synthesis, gate decomposition, routing optimization for specific hardware topologies, and hybrid classical-quantum workflow management. Cloud integration through established quantum platforms enables seamless deployment of compiled quantum programs across multiple hardware providers, reducing the technical barriers for quantum application development. The open-source model facilitates rapid iteration and community-driven innovation, leveraging collective global expertise to accelerate quantum software development beyond what individual organizations could achieve independently. Error correction integration prepares the compilation framework for future fault-tolerant quantum systems while maintaining compatibility with current noisy intermediate-scale quantum devices.
