For this state, we demonstrate genuine six-qubit entanglement, persistency of en...<br/>[Phys. Rev.

This method dramatically reduces the truncation error of the tensor renormalization group. It allows physical quantities of classical tensor-network models or tensor-network ground states of quantum syste...<br/>[Phys. Rev. Lett. 103, 160601] Published Mon Oct 12, 2009 Z. Y. Xie, H. C.
