The First Workshop on Quantum Computing for Classical Computational Challenges in HPC (QC4C3) will be held with QCNC 2026. We invite researchers, practitioners, and experts from academia and industry to submit their original and innovative research on quantum computing and related technologies.
Paper Submission
Topics of interest include but are not limited to:
Hybrid Quantum–HPC Architectures:
Integration of quantum processors within high-performance computing workflows, including orchestration, scheduling, and resource management.
Quantum and Quantum-Inspired Optimization:
Algorithms such as QAOA, RQAOA, and Ising-based heuristics for large-scale combinatorial and continuous optimization problems.
Quantum Machine Learning and AI:
Variational, kernel-based, and tensor-network models for scalable learning, inference, and data-driven discovery across hybrid environments.
Computational Fluid Dynamics (CFD) and Scientific Simulation:
Quantum linear solvers, operator-learning strategies, and quantum lattice Boltzmann methods for multi-physics modeling.
Benchmarking, Validation, and Reproducibility:
Standardized evaluation frameworks for comparing quantum, classical, and hybrid methods in real-world computational settings.
Resource Estimation and Performance Modeling:
Quantitative studies on circuit depth, qubit requirements, and runtime scaling for near-term and fault-tolerant quantum systems.
Quantum-Inspired Algorithms on Classical HPC:
Tensor-network, annealing-based, and stochastic techniques leveraging classical supercomputing resources.
Software Frameworks and Middleware for Hybrid Workflows:
Tools enabling quantum–HPC co-execution, data exchange, and workflow automation.
Industrial and Scientific Applications:
Case studies in logistics, finance, energy systems, materials design, and telecommunications demonstrating quantum–classical synergy.

Submission Guidelines
Accepted and presented papers will be published in the IEEE QCNC 2025 Conference Proceedings and submitted to IEEE Xplore®. Submitted papers must be written in English, with a maximum length limit of 6 printed pages. The main text (including figures, tables, appendices, and any material other than references) must be no more than 6 pages. Papers that do not comply with the length limit will not be reviewed. Use the standard IEEE Transactions templates for Microsoft Word or LaTeX formats found at: https://www.ieee.org/conferences/publishing/templates.html
If the paper is typeset in LaTeX, please use an unmodified version of the LaTeX template IEEEtran.cls version 1.8, and use the preamble: \documentclass[10pt, conference, letterpaper]{ IEEEtran }
Do not use additional LaTeX commands or packages to override and change the default typesetting choices in the template, including line spacing, font sizes, margins, space between the columns, and font types. This implies that the manuscript must use 10-point Times font, two-column formatting, as well as all default margins and line spacing requirements as dictated by the original version of IEEEtran.cls version 1.8. If you are using Microsoft Word to format your paper, you should use an unmodified version of the Microsoft Word IEEE Transactions template (US letter size). Regardless of the source of your paper formatting, you must submit your paper in Adobe PDF format.
The paper must print clearly and legibly, including all the figures, on standard black-and-white printers. Reviewers are not required to read your paper in color. The submitted manuscript should be self-contained. Inclusion of additional material (e.g., a technical report containing the detailed math proof through an anonymous Dropbox or OneDrive link) is not allowed.
