Abstract
► Quantum discord may exhibit long-range decay in spin systems. ► Long-range behavior of discord occurs as the system crosses a critical point. ► Long-range behavior of discord is found for phase transitions of different orders. ► Discussion of discord as a function of distance is shown for several spin chains.
