We propose that a minimal bond cut surface is characterized by entanglement
distillation in tensor networks. Our proposal is not only consistent with the
holographic models of perfect or tree tensor networks, but also can be applied
for several different classes of tensor networks including matrix product
states and multi-scale entanglement renormalization ansatz. We confirmed our
proposal by a numerical simulation based on the random tensor network. The
result sheds new light on a deeper understanding of the Ryu-Takayanagi formula
for entanglement entropy in holography.Comment: 8 pages, 9 figure
