Pairing diagram — Fig. 15(a). Adam Nahum, Brian Skinner. Entanglement and dynamics of diffusion-annihilation processes with Majorana defects. Physical Review Research 2, 023288 (2020). Used under CC BY 4.0. Pairing diagram reproduced with the (a) label removed. It shows a fixed 2D Majorana lattice under random measurements, without annihilation.
