Density Matrix Renormalization Group and Periodic Boundary Conditions: A Quantum Information Perspective

Year: 2004

Type: article

Abstract: We introduce a picture to analyze the density matrix renormalization group (DMRG) numerical method from a quantum information perspective. This leads to a variational formulation of DMRG which allows for dramatic improvements in the case of problems with periodic boundary conditions. The picture also explains some features of the method in terms of entanglement and teleportation.
