摘要：
由于量子技术的快速发展，传统的经典密码协议已不再安全。为了实现世界的量子安全，人们考虑了不同的量子协议。量子密钥分发（QKD）协议就是其中之一，两方可以通过坚持量子原理进行安全通信。在各种QKD协议中，相干单向（COW）协议因其硬件部署简便和对PNS攻击的强抗性而成为最著名的协议之一。在此项研究中，我们在Optisystem v21.1中实现了双脉冲COW QKD协议的原始版本及其最新变体——三脉冲COW（Phys. Rev. Applied 18, 064053 Published 19 December 2022）。我们在考虑不同天气条件的噪声和无噪声场景下，演示了协议的编码和解码部分。最后，我们报告了在有线（光纤）和无线（自由空间）环境下协议间的比较研究，以检查传输的完整性。仿真结果为我们提供了不同天气条件下协议实际实施的概览。
英文摘要：
Due to the rapid advancement of quantum technology, the traditional established classical cryptographic protocols are no longer secure. To make the world quantum safe, different quantum protocols have been taken into account. Quantum Key Distribution (QKD) protocols are one of them where two legitimate parties can securely communicate by upholding the quantum principles. Out of various QKD protocols, Coherent One Way (COW) protocol is one of the most famous protocol because of its ease of hardware deployment, and resilience nature towards PNS attack. In this initiative, we have implemented the original version of two pulses COW QKD protocol and a very recent variant of it, three pulses COW (Phys. Rev. Applied 18, 064053 Published 19 December 2022), in Optisystem v21.1. We demonstrate the encoding as well as decoding portions of the protocols under both noisy and noiseless scenario considering different weather conditions. Finally, we report a comparative study amongst the protocols under wired (optical fibre) and wireless (free space) environments to check the proper integrity of transmission. The simulation results provide us an overview regarding the practical implementation of the protocols under different weather conditions.
