论文摘要
在本文中，提出了一台称为概率量子删除机器的广义输入状态删除机。将Pati-Braunstein删除机视为基准，该机器的特征是其删除概率和删除错误的概率。据观察，有一些参数会增加缺失误差的增加可以增加删除的保真度。还表明，Pati-Braunstein删除机很容易衍生，以具有一定的缺失概率值。此外，对于任何具有正确参数的输入状态，删除机可以比Pati-Braunstein删除机提供更好的删除保真度。
In this paper, a generalized input state dependent deletion machine called probabilistic quantum deletion machine is proposed. Considering the Pati-Braunstein deletion machine as a benchmark, the machine is characterized by its deletion probability and the probability of error in deletion. It is observed that there are parameters for which increase in error in deletion can increase the fidelity of deletion. It is also shown that the Pati-Braunstein deletion machine is easily derivable for a certain value of deletion probability. Further the deletion machine can offer better fidelity of deletion than the Pati-Braunstein deletion machine for any input state with the right parameters.
