A triquantum wave is an energy phenomenon which can accompany the opening of a transwarp conduit.

In 2353, Erin and Magnus Hansen, exobiologists studying the Borg, detected triquantum waves, subspace disruptions with a field magnitude of 2.9 teracochranes, and a highly-symmetric power-utilization curve. These readings proved to be characteristic of a transwarp conduit, generated by a Borg cube. (VOY: "Dark Frontier")
