利用腔QED系统中光子极化的法拉第旋转，提出了一种确定性传送纯量子态的方案。该方案基于腔场的单光子输入-输出过程，即使在低Q腔中也能很好地工作。由于只涉及原子的虚激发，它对原子的自发辐射也不敏感。此外，该方案不需要用法拉第旋转代替CNOT操作，大大降低了实验难度。
We propose a scheme for deterministically teleporting a pure quantum state, making use of the Faraday rotation of photonic polarization in cavity QED system. Based on the single-photon input-output process regarding cavities, the scheme works well even in low-Q cavities. Since only virtual excitation of the atoms is involved, it is also insensitive to atomic spontaneous emission. Besides, the CNOT operation replaced by the Faraday rotation is not needed in the scheme, which could greatly relax the experimental difficulty.
