In low-temperature superﬂuid helium, viscosity is zero and vorticity takes the form of discrete vortex ﬁlamentsof ﬁxed circulation and atomic thickness. We present numerical evidence of three-dimensional inverse energytransfer from small length scales to large length scales in superﬂuid turbulence generated by a ﬂow of vortexrings. We argue that the effect arises from the anisotropy of the ﬂow, which favors vortex reconnections of vortexloops of the same polarity, and that it has been indirectly observed in the laboratory. The effect opens questionsabout analogies with related processes in ordinary turbulence.
