International Workshop on Massively Parallel Programming for Quantum Chemistry and Physics (MPQCP 2026)

Focus:
MPQCP (2026) is the seventh in a series of annual international workshops that bring together researchers interested in employing advanced computational techniques to advance chemistry and physics with special emphasis on few and many-body quantum systems. Relevant topics include, but are not limited to, supercomputing, numerical representations and algorithms, advanced software development, applications of AI, quantum computing, physical applications, and new theoretical formulations and models. This year, we will focus on recent developments of programs and algorithms in quantum chemistry, condensed matter physics, and particle/nuclear physics. The main goals for this workshop are to build international collaborations and to share, through multidisciplinary discussions, experience and expertise with special focus on software and numerical techniques.
SCA/HPCAsia 2026:
This year's workshop will be held before the SCA/HPCAsia 2026. We encourage participants to enjoy both events.
