In this work we show evidence for a superfluid analog to the classical dissipation anomaly: When the friction tends to zero, the dissipation does not vanish, but levels off to a constant non-zero value. This characteristic stems from the generation of smaller and smaller structures on the quantized vortex lines as the friction is lowered. This property of quantum turbulence is universal, not depending on the dynamics of the large scales.
