Meta-VQE

This is the repository for the article "The Meta-Variational Quantum Eigensolver (Meta-VQE): Learning energy profiles of parameterized Hamiltonians for quantum simulation", Alba Cervera-Lierta, Jakob S. Kottmann, Alán Aspuru-Guzik, arXiv:2009.13545[quant-ph].

Content:

• data folder: contains all data presented in the main article.
• img folder: contains the plots of the main article and other plots generated with the available data.
• Meta-VQE demo: jupyter notebook with the source code used to run the simulations.
• Molecular-Meta-VQE demo: An explicit illustration of a non-linear meta-VQE for molecules as described in the article.
• transmon: main code to obtain the results for the single-transmon simulation.

Dependencies:

You will need tequila to run the notebooks.
Just follow the instructions on the github page. If you are using Linux, you can clone this repository and run pip install . to install tequila form the setup.py file provided here.
If you are using Mac or Windows, you probably need to install the qulacs simulator manually (or alternatively any other suported quantum backend) -- see the tequila github page.
