7th International Workshop on
Quantum Compilation
6-7 September 2025
Helsinki, Finland
About the workshop
The workshop aims to bring together researchers from quantum computing, electronic design automation, and compiler construction. Open questions that we anticipate this group to tackle include new methods for circuit synthesis, optimization, and rewriting, techniques for verifying the correctness of quantum programs, and new techniques for compiling efficient circuits and protocols regarding fault-tolerant and architecture constraints.
The main purpose of the workshop is to exchange recent ideas and research in the area of quantum compilation. Topics of interest for the workshop include:
- Depth- and space-optimizing compilers for quantum circuits
- Quantum and reversible circuit peep-holing and (re)synthesis
- Reversible logic synthesis
- Technology-aware mapping
- Fault-tolerant circuit compilation
- Quantum programming languages
- Intermediate representations for quantum software
- Optimized libraries (e.g., for arithmetic and Hamiltonian simulation)
- Benchmarking of circuits for small and medium scale quantum computers
- Design-space exploration for automatic code generation from classical HDL specification
- Software and tools for all above mentioned topics
- Quantum outreach: coding contests, tutorials, education
The workshop has no formal proceedings. Authors are invited to submit an abstract of 3--5 pages in length. Submission of tool and case-study papers are highly encouraged. Links to longer documents or source code respositories are permitted, although the referees may or may not refer to them. In case of a positive evaluation, submissions are accepted either as oral or poster presentation to be part of the workshop programme. All abstracts and papers are distributed only among the participants, but can be shared on the workshop's website with the author's consent.
Accepted submissions should be presented in person in Helsinki — please note the workshop dates! Submissions must point out who will present the contribution if it is selected.
