Summary
🤩
RockstarMax Rossmannek is a software engineer and quantum chemistry researcher with nine years of hands-on experience bridging computational chemistry and quantum computing. He is currently pursuing a PhD at the University of Zurich while researching quantum algorithms for quantum chemistry at IBM Research Zurich, building on a master's thesis that developed a hybrid quantum-classical electronic structure approach. Max contributes actively to major open-source projects—most notably Qiskit and Taskwarrior—where his work ranges from implementing UCC ansätze and ADAPT‑VQE fixes to pragmatic backend bug fixes and UI/documentation improvements. Comfortable across the stack, he has improved core quantum SDK features, refined tutorials for community adoption, and enhanced developer tools in both Python and Lua ecosystems. Colleagues will notice his dual focus on scientific rigor and production-quality software: he writes tests, refactors for clarity, and improves usability in tools used by both researchers and practitioners. Based in Switzerland, he blends academic depth with practical open-source impact in quantum software.

Sep 2019 - Jan 2023
Qiskit Nature is an open-source, quantum computing, framework for solving quantum mechanical natural science problems.
Role in this project:
Back-end Developer
Back-end DeveloperContributions:6 releases, 1891 reviews, 182 commits in 3 years 5 months
Contributions summary:Max's commits focus on implementing the Unitary Coupled-Cluster (UCC) ansatz, a method for solving quantum mechanical natural science problems. The primary contribution is adding the `ucc.py` file which defines the UCC Ansatz. This includes defining methods for calculating excitations and implementing the circuit. Subsequent commits involve refactoring and updating the UCC implementation, including adding support for generalized fermionic excitations and fixing existing functionalities.
