MERA (Multi-scale Entanglement Renormalization Ansatz): SVD-based scale-invariant tensor network

Layer 1 — Physicsin the quantum-simulation subtree

Multi-scale Entanglement Renormalization Ansatz (Vidal 2007). Setup: a 1D (or 2D) quantum state on N sites represented as a hierarchical tensor network with two kinds of tensors at each level: disentanglers U_l (unitary, remove short-range…
