Differential phase shift quantum secret sharing using a twin field
Optics express, 2021Co-Authors: Xiao-yu Cao, Hua-lei Yin, Zeng-bing ChenAbstract:Quantum secret sharing (QSS) is essential for multiparty quantum communication, which is one of cornerstones in the future quantum internet. However, a linear rate-Distance Limitation severely constrains the secure key rate and transmission Distance of QSS. Here, we present a practical QSS protocol among three participants based on the differential phase shift scheme and twin field ideas for the solution of high-efficiency multiparty communication task. In contrast to a formerly proposed differential phase shift QSS protocol, our protocol can break the linear rate-Distance bound, theoretically improving the secret key rate by three orders of magnitude in a 300-km-long fiber. Furthermore, the new protocol is secure against Trojan horse attacks that cannot be resisted by previous differential phase shift QSS.

Combating Distance Limitation for communications within Multiple Micro-Grids by Virtual routers
2016 International Conference on Electrical Power and Energy Systems (ICEPES), 2016Co-Authors: Meena Agrawal, Chaitanya P. AgrawalAbstract:Worldwide Smart Grids are emerging nowadays as foremost concern infrastructure upgrade programs. The Smart Grid paradigm represents a transition towards an intelligent, digitally enhanced, two-way power delivery grid envisioned to materialize as a properly designed plug-and-play integration of smart Multiple Micro-Grids. These all are envisioned to be interconnected through dedicated control & communication highway for signal, command, data and power transfer. Exchange of information among power system actors is the key to success of Smart Multiple Micro-Grids. Exceptional concerns are being given to the design of efficient and robust communication network capable of managing operation and control of the coming generation power grid smartly. For the rationale new wired and wireless technologies are budding in addition to the previously applied ones to help upgrade the existing power grid. This paper provides a brief overview of smart grid communications requirements and the established interoperability standards. The authors also present a bird's eye view on the progress of wired and wireless communication technologies for smart grid communication infrastructure. The authors have proposed and implemented new micro grid control & measurement way by employing Virtual Wi-Fi routers for communications amongst various entities of the smart micro grid. Standalone devices have also been converted to virtual router for integration in the network by using virtual utilities.

Extending transmission Distance of high-density WDM systems using post transmitter fiber Raman amplifiers
Journal of Lightwave Technology, 1991Co-Authors: Ming-seng KaoAbstract:The authors investigate the behavior of multichannel signals in a high-density wavelength division multiplexing (WDM) system with the consideration of stimulated Raman scattering. A parameter to evaluate the depth of Raman crosstalk is provided, and the transmission Distance Limitation imposed by Raman crosstalk is analyzed. To extend the system transmission Distance, a post-transmitter fiber Raman amplifier is used. The allocation of signal channels on the pump gain profile is discussed. It is found that there exists an optimum pump power which results in a maximum amplifier gain. The example shows that the transmission Distance Limitation imposed by Raman crosstalk can be extended by 20 km for a 30-channel system with 0.25-dB/km fiber loss. >
