The continued development of computational approaches to many-body ground-state problems in physics and chemistry calls for a consistent way assess its overall progress. In this work, we introduce metric variational accuracy, the V-score, obtained from energy variance. We provide an extensive curated dataset calculations quantum systems, identifying cases where state-of-the-art numerical show limited accuracy future algorithms or platforms, such as computing, could improved accuracy. V-score...

We investigate the physics of projected d-wave pairing states using their fermionic entangled pair state (fPEPS) representation. First, we approximate a Bardeen-Cooper-Schrieffer Gaussian fPEPS. Next, translate resulting into fPEPS tensors and implement Gutzwiller projection which removes double occupancy by modifying local tensor elements. The network representation allows us to evaluate physical quantities in thermodynamic limit without employing approximation. Despite having very few...
