Abstract

In this paper, we investigate theoretically the back-action evading measurement of the collective mode of an interacting atomic Bose–Einstein condensate (BEC) trapped in an optical cavity that is driven coherently by a pump laser with a modulated amplitude. It is shown that, for a specified kind of amplitude modulation of the driving laser, one can measure a generalized quadrature of the collective mode of the BEC indirectly through the output cavity field with a negligible back-action noise in the good-cavity limit. Nevertheless, the on-resonance added noise of measurement is suppressed below the standard quantum limit (SQL), even in the bad cavity limit. Moreover, the measurement precision can be controlled through the $ s $-wave scattering frequency of atomic collisions.
