论文摘要
我们提出了一个方案，以实现对腔中手性分子的精确歧视。在其他激光脉冲的辅助下，腔场可以根据分子的惯用性而演变为具有相反符号位移的不同连贯状态。因此，可以通过对腔体的同源测量来读取分子的惯性，并且成功的概率几乎是统一的，而没有非常强大的腔场。数值结果表明，该方案对错误，噪声和谐波不敏感。因此，该方案可以为精确歧视手性分子提供有用的观点。
We present a scheme to realize precise discrimination of chiral molecules in a cavity. Assisted by additional laser pulses, cavity fields can evolve to different coherence states with contrary-sign displacements according to the handedness of molecules. Consequently, the handedness of molecules can be read out with homodyne measurement on the cavity, and the successful probability is nearly unity without very strong cavity fields. Numerical results show that the scheme is insensitive to errors, noise and decoherence. Therefore, the scheme may provide helpful perspectives for accurate discrimination of chiral molecules.
