Hierarchy of Topological Order From Finite-Depth Unitaries, Measurement, and Feedforward
Long-range entanglement—the backbone of topologically ordered states—cannot be created in finite time using local unitary circuits, or, equivalently, adiabatic state preparation. Recently, it has come to light that single-site measurements provide a loophole, allowing for finite-time state preparati...
