论文摘要
在本文中，使用非线性相干状态的概念，我们定义了一个变形的骨发性通道模拟Kerr培养基对量子状态的影响，例如，在基于光纤基于光纤的量子通信中。我们表明，在某些制度中，克尔的非线性能够补偿这种诉讼。此外，我们的研究表明，对于某些非线性参数，变形的玻色剂脱位通道的量子能力可能大于未呈现的标准玻色剂驱动通道的量子能力。
In this paper, using the notion of nonlinear coherent states, we define a deformed bosonic dephasing channel modelling the impact of a Kerr medium on a quantum state, as it occurs, for instance, in quantum communication based on optical fibers. We show that, in certain regimes, the Kerr nonlinearity is able to compensate the dephasing. In addition, our studies reveal that the quantum capacity of the deformed bosonic dephasing channel can be greater than that of the undeformed, standard bosonic dephasing channel for certain nonlinearity parameters.
