Deterministic teleportation of atomic state in dephasing environment

  • 摘要: 为了减小噪声环境对量子隐形传态的影响,针对去相环境噪声,提出了一种基于免退纠缠态和量子错误避免代码技术的量子隐形传态抗噪方案。在该方案中,将免退纠缠态的四量子比特作为量子纠缠信道,被传输的量子信息编码到两个量子比特。结果表明,整个隐形传输过程不会受到去相环境噪声的影响,并且具有100%成功几率。该研究对量子通讯的发展是有帮助的。
    Abstract: In order to decrease the effect of noisy environment on quantum teleportation, the scheme of quantum teleportation in the dephasing noisy environment based on the disentanglement-free state and quantum error-avoiding code was proposed. In this scheme, disentanglement-free atomic four quantum bit state was taken as the quantum entanglement channel, and the teleportated quantum information was encoded into two quantum bits. The results show the whole teleportation process is not affected by the noisy environment and the success probability for this teleportation scheme is 100%. This research is helpful to improve quality of the quantum communication
