我们提出了一种通过一系列两个量子非破坏测量来检测自旋气体基态量子相的方法，这些测量是通过向气体发送非共振偏振光脉冲来进行的。识别了通过检测量子涨落和透射光偏振平均值获得的F=1和F=2旋量气体的各种平均场和强相关相位的特征。
We propose a method for the detection of ground state quantum phases of spinor gases through a series of two quantum nondemolition measurements performed by sending off-resonant, polarized light pulses through the gas. Signatures of various mean-field as well as strongly correlated phases of F=1 and F=2 spinor gases obtained by detecting quantum fluctuations and mean values of polarization of transmitted light are identified.
