What is it about?
This article introduces an open-source software tool that extends the Quantum Learning Machine (QLM), a quantum computing platform, to enable advanced simulations in quantum chemistry. The focus is on implementing the Variational Quantum Eigensolver (VQE), a key algorithm used to study the electronic structure of molecules. The VQE is particularly important in quantum chemistry because it helps calculate molecular energies, which are critical for understanding chemical reactions and properties. The authors describe how their extension integrates with the QLM to make quantum simulations more accessible and adaptable for researchers in chemistry and quantum computing. By providing this tool as open-source software, the authors aim to foster collaboration and innovation in the quantum chemistry community, enabling others to test and improve their methods on both quantum simulators and real quantum hardware. The paper includes examples and case studies demonstrating the application of this tool in solving real-world quantum chemistry problems, emphasizing its efficiency and ease of use.

Writing this article was a truly rewarding experience, as it marked a collaboration with ATOS, a company at the forefront of quantum computing and technological innovation. This partnership allowed me to combine cutting-edge research with practical applications, paving the way for impactful contributions to the quantum computing community. The creation of OpenVQE as an open-source platform has been particularly fulfilling. It offers students, engineers—both specialists and non-specialists—a unique opportunity to engage with quantum algorithms, bridging the gap between theory and real-world application. Empowering learners and researchers through accessible tools like OpenVQE is at the heart of my vision for quantum education. Stay tuned for the upcoming second version of OpenVQE, where we will introduce even more advanced features and capabilities, further expanding the horizons of quantum collaboration and innovation!
