+Advantage2_system2.1
+====================
+
+All data presented in this section are specific to the **Advantage2_system2.1**
+solver. The |adv2| system QPU is based on a physical lattice of qubits and
+couplers known as the *Zephyr* topology. For information, see the
+:ref:`topology_intro_zephyr` section.
