Abstract: We propose a pump scheme for quantum circulations, including countercirculations for superposition states, of a spinor Bose-Einstein condensate. Our scheme is efficient and can be implemented within current experimental technologies and setups. It remains valid for nonclassical atomic states, such as pseudo-spin-squeezed states and maximally entangled $N$-particle Greenberger-Horne-Zeilinger ($|N,0\ensuremath{\rangle}+|0,N\ensuremath{\rangle}$) states. Moreover, it is capable of transforming several enhanced sensing protocols relying on reduced fluctuations from quantum correlation and entanglement of atomic internal states to enhanced measurement of spatial interference and rotation.
