Quantum simulations consist in the intentional reproduction of physical or unphysical
models into another more controllable quantum system. Beyond establishing …

Projected entangled pair states (PEPS) are a promising ansatz for the study of strongly
correlated quantum many-body systems in two dimensions. However, due to their high …

We propose a systematic procedure for the approximation of density functionals in density
functional theory that consists of two parts. First, for the efficient approximation of a general …

Superconducting circuits have become a leading quantum platform for the implementation of
quantum information tasks. Here, we revise the basic concepts of circuit network theory and …

In the context of strongly correlated fermions on a one-dimensional lattice, we propose to
use matrix product states to construct approximate density functionals for density functional …

The complexity of physical systems in nature is an obstacle for human desire and curiosity to
explore new realms of knowledge. As we go further and further, more powerful computers …
