    "abstract": "We introduce the multi-scale entanglement renormalization ansatz (MERA), an\nefficient representation of certain quantum many-body states on a D-dimensional\nlattice. Equivalent to a quantum circuit with logarithmic depth and distinctive\ncausal structure, the MERA allows for an exact evaluation of local expectation\nvalues. It is also the structure underlying entanglement renormalization, a\ncoarse-graining scheme for quantum systems on a lattice that is focused on\npreserving entanglement.",
