Sequential Generation of Two-dimensional Super-area-law States with Local Parent Hamiltonian
arXiv:2505.02914 · doi:10.1103/t7py-glgv
Abstract
We construct examples of highly entangled two-dimensional states by exploiting a correspondence between stochastic processes in dimensions and quantum states in dimensions. The entanglement structure of these states, which we explicitly calculate, can be tuned between area law, sub-volume law, and volume law. This correspondence also enables a sequential generation protocol: the states can be prepared through a series of unitary transformations acting on an auxiliary system. We also discuss the conditions under which these states have local, frustration-free parent Hamiltonians.
