  This paper reviews briefly the recent important developments in the physics
of quantum turbulence (QT) in superfluid helium and atomic Bose-Einstain
condensates (BECs). After giving basics of quantum hydrodynamics, we discuss
energy spectrum, QT created by vibrating structures, visualization among topics
on superfluid helium. For atomic BECs we review three-dimensional QT,
two-component BECs, and spin turbulence in spinor BECs. The last part is
devoted to some perspectives of this issue.
