摘要翻译：
量子密码学的一个有吸引力的实现是连续变量变化，因为它依赖于标准的电信组件。使用高斯格式调制量子信号是很有吸引力的，因为它已经被证明是安全的。在模拟的背靠背结构中，研究了根升余弦脉冲整形和匹配滤波器的滚降对高斯调制量子密钥分配系统剩余噪声性能的影响。与直觉相反，滚降参数对系统性能的影响并不显著。

英文摘要：
  An attractive implementation for quantum cryptography is the continuous variable variation, as it relies on standard telecommunication components. Modulating the quantum signal using a Gaussian format is attractive since it has been proven to be secure. This work investigates the effect of the roll-off of a root raised cosine pulse shaping and matched filter on the excess noise performance of a Gaussian modulated quantum key distribution system in a simulated back to back configuration. Contrary to intuition, it is found that the roll-off parameter does not significantly impact the performance of the system.
