WQS 2026 — 4th Workshop on Quantum Software

Quantum software development is becoming a critical skill as quantum computing matures from theory to practice. The Workshop on Quantum Software (WQS) addresses the intermediate layers of the quantum computing stack — from high-level algorithms down to hardware implementation.

WQS 2026 is the fourth edition of this workshop. It was inaugurated at QTML 2022 in Naples , followed by PLDI 2024 in Copenhagen and PLDI 2025 in Seoul . This year, we are returning to QTML — bringing together researchers and practitioners working on quantum programming languages, compilers, verification, and the software-hardware interface.

This year, WQS is co-located with QTML 2026 (Quantum Techniques in Machine Learning) in Stellenbosch, South Africa — creating a unique opportunity to connect the quantum software and quantum machine learning communities.

High-level programming language definition through machine-independent syntax and semantics specifications for quantum computation.

Structured methodologies for translating high-level quantum programs into executable form — bridging the gap between abstraction and hardware.

Analysis of program properties, verification techniques, and compiler optimization — ensuring correctness in quantum software.
