Abstract

In this paper, using the notion of nonlinear coherent states, we define a deformed bosonic dephasing channel modeling 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.

变形玻色子脱相信道的量子容量

在本文中，使用非线性相干态的概念，我们定义了一个变形玻色子脱相通道，模拟了克尔介质对量子态的影响，例如，在基于光纤的量子通信中。我们证明，在某些情况下，克尔非线性能够补偿减相。此外，我们的研究表明，在某些非线性参数下，变形玻色子脱相通道的量子容量可以大于未变形的标准玻色子脱相通道的量子容量。
