Matrix Product Density Operators: Renormalization Fixed Points and Boundary Theories
J. I. Cirac, D. Perez-Garcia, N. Schuch +1
We consider the tensors generating matrix product states and density operators in a spin chain. For pure states, we revise the renormalization procedure introduced by F. Verstraete…

Tensor networks and efficient descriptions of classical data
Sirui Lu, Márton Kanász-Nagy, Ivan Kukuljan +1
We investigate the potential of tensor network based machine learning methods to scale to large image and text data sets. For that, we study how the mutual information between a su…
