QCCC-26: The 5th International Workshop on Quantum-Classical Cooperative Computing
Half-Day Workshop at ISCA 2026 — June 27, 2026

Recent years have brought remarkable advances in quantum computing, transitioning from early noisy-intermediate-scale quantum (NISQ) devices to increasingly sophisticated fault-tolerant quantum computing (FTQC) systems. As these systems continue to evolve, harnessing the power of quantum devices in conjunction with classical computing has emerged as a promising path for addressing scientific and engineering challenges. The 5th International Workshop on Quantum-Classical Cooperative Computing (QCCC-26) seeks to explore innovative approaches, architectures, and software techniques that enable seamless integration between quantum and classical computing platforms, aiming to enhance the scalability, reliability, and practical impact of quantum computing.

Topics of Interest

We welcome submissions addressing quantum-classical cooperative computing (QCCC) in theory, architecture, algorithms, or system design. Relevant topics include, but are not limited to:

• Architectural support for quantum-classical cooperative computing
• Quantum-classical hybrid algorithms
• Hardware/software co-design for QCCC
• Quantum error correction
• Quantum random access memory
• Architectures for distributed quantum computing
• Quantum resource estimation and management
• Circuit decomposition, integration, and transpilation techniques
• Encoding/decoding classical information into/from quantum states
• Quantum error mitigation strategies
• Variational quantum algorithms (VQA)
• Early Fault-tolerant algorithm and architecture design
• Other QCCC approaches and architectures

(Please note that purely quantum or purely classical algorithm/hardware design, as well as general benchmarking without emphasis on hybridization, fall outside the scope of this workshop.)

Submission Guidelines

• Submission Format: Extended abstracts of 2–4 pages (excluding references) are strongly encouraged.
• Submission Site: A link to EasyChair or a relevant submission platform will be provided on the workshop website
• Publication: Accepted abstracts will appear in the workshop proceedings. Authors remain free to submit a full version of their work to another venue in the future.
