Abstract
We propose a symmetric version of the multiscale entanglement renormalization ansatz in two spatial dimensions (2D) and use this ansatz to find an unknown ground state of a 2D quantum system. Results in the simple 2D quantum Ising model on the square lattice are found to be very accurate even with the smallest nontrivial truncation parameter.
