# QUEASARS - Quantum Evolving Ansatz Variational Solver

QUEASARS is an open-source, qiskit-based, python package implementing quantum variational eigensolvers which use evolutionary algorithms to find a good ansatz during the optimization process, like [E-VQE](https://arxiv.org/abs/1910.09694), [MoG-VQE](https://arxiv.org/abs/2007.04424) or [QNEAT](https://arxiv.org/abs/2304.06981).
Currently only EVQE is implemented.

QUEASARS is developed as part of a research project of the Quantum Space Operations Center ([QSOC](https://qsoc.space)) at the German Space Operations Center ([GSOC](https://www.dlr.de/en/research-and-transfer/projects-and-missions/iss/the-german-space-operations-center)).
