Tensor Network Contraction
MPS/DMRG-style tensor network — bond dimensions, index contraction, and SVD truncation
MPS Parameters
Number of sites L:
6
Bond dimension χ:
4
Physical dim d:
2
SVD truncation ε:
0.10

MPS: Ψ = Σ A[1]A[2]...A[L]|s₁s₂...sL⟩ Bond dim χ = 4 Truncation ε = 0.10
Each tensor A[i] has shape χ×d×χ
Contraction: sequential matrix products
SVD keeps singular values σ > ε·σ_max
Entanglement entropy S = -Σ σ²log σ²
