The iX magazine, a well-established format by the German Heise publishing company for a professional IT audience, was putting together a comprehensive introduction on quantum computing from a practical computing perspective as a special edition. It was release on 10th June 2021 ( ).

We contributed with an article on Google’s Open Source Python library Cirq introducing its basic code mechanics ( ). Further it aims to provide a compact overview of Cirq’s broad functionality ranging from efficient classical quantum simulation, introducing noise on the local and global level over enforcing device restrictions to real QPU-backend sampling.

To conclude this educational article, we showcase with a small Variational Quantum eigensolver (VQE) example a typical Noisy Intermediate Scale Quantum (NISQ) era application (
