Noise suppression in the co-propagation of quantum signals and classical optical signals by Yongmei SUN, Jianing NIU, Yuefeng JI

“…At present,the technologies of device and system required for the fiber-based point-to-point quantum key distribution (QKD) are gradually becoming mature and showing the trend of commercial application.Therefore,how to multiplex quantum signals and classical optical signals in a single fiber to greatly increase the capacity and save fiber resources has been becoming one of the hotspots of academia in recent years.The noise impairments in the co-propagation of quantum signals and classical optical signals over a single fiber were mainly studied.Firstly,the influences of the main noises,four-wave mixing (FWM) and Raman scattering on the quantum channels were analyzed.Next,an unequal-frequency-spacing-based FWM noise suppression algorithm and a wavelength assignment algorithm for joint suppression of FWM and Raman scattering were proposed for different application scenarios with different channel space and transmission distance.Finally,the superiorities of the proposed algorithms were verified through numerical simulations.The research results provide feasible noise suppression schemes for different application scenarios in the future.…”

Classical and Impulse Stochastic Control on the Optimization of Dividends with Residual Capital at Bankruptcy by Peimin Chen, Bo Li

“…Maximization of both expected total discounted dividends before bankruptcy and expected discounted returned money at the state of terminal bankruptcy becomes a mixed classical-impulse stochastic control problem. In order to solve this problem, we reduce it to quasi-variational inequalities with a nonzero boundary condition. …”
