Abstract

To calculate the entanglement parameter of two light soliton pulses in the optical fiber, the use of a discrete representation of the classical part of the field is proposed. It is shown that two soliton pulses in optical fiber, which were produced as a result of the fission of two-soliton breather in the fiber with periodic dispersion, are entangled, the entangled parameter is Schmidt information, calculated for a system with continuous variables. It has been shown that entanglement is preserved during the propagation of a pair of the pulses in an optical fiber at large distance, about 100000 dispersion lengths. Schmidt information is calculated for different propagation regimes of two soliton pulses in a fiber depending on the pulse parameters: amplitudes, frequency shifts, phase and time shifts of maxima.

用场离散和施密特分解计算光纤中孤子脉冲的纠缠

为了计算光纤中两个光孤子脉冲的纠缠参数，提出了使用经典场的离散表示。结果表明，光纤中具有周期色散的双孤子呼吸体裂变产生的两个孤子脉冲是纠缠的，其纠缠参数为连续变量系统的施密特信息。研究表明，在光纤中，一对脉冲在大距离（约100,000色散长度）的传输过程中，纠缠态是保留的。根据两个孤子脉冲的脉冲参数：最大值的幅值、频移、相移和时移，计算了两个孤子脉冲在光纤中不同传播状态下的施密特信息。

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
