The macroscopic quantum states of the dilute bosonic ensemble in helical laser trap at the temperatures about $10^{-6}\bf {K}$ are considered in the framework of the Gross-Pitaevskii equation. The helical interference pattern is composed of the two counter propagating Laguerre-Gaussian optical vortices with opposite orbital angular momenta and this pattern is driven in rotation via angular Doppler effect. The macroscopic observables including linear momentum and angular momentum of the atomic cloud are evaluated explicitly . The detection of quantized rotations in a current lab environment is discussed.
