(a) Initial plaquette configuration, \(|0\rangle\). (b) The third plaquette is flipped, resulting in the state \(|3\rangle\). (c) The third and the sixth plaquettes are flipped, leading to the state \(|3,6\rangle\). Note that we do not need to determine explicitly the blocked plaquettes, or follow why they are blocked. The states are fully defined by stating which plaquettes have been flipped compared to the initial state (a).
