We propose the unidimensional continuous-variable quantum key distribution(UDCVQKD) protocol based on the basis-encoding of Gaussian modulated coherent states. the UDCVQKD protocol disregards the necessity in one of the quadrature modulations in coherent states. On that basis, we propose our scheme by encoding the secret keys on the either randomly selected measurement bases: the phase quadrature (X) or the amplitude quadrature (P), in order to slightly weaken the effects of reconciliation efficiency and channel excess noise compare to the present UCVQKD protocol. The new protocol with a view to simplify the precedent unidimensional protocols in the decoding procedure, meanwhile ensure the security of the quantum communication.

基于基编码相干状态协议的一维连续变量量子密钥分配

我们提出了基于高斯调制相干态基编码的一维连续变量量子密钥分配（UDCVQKD）协议。UDCVQKD 协议忽略了相干状态正交调制之一的必要性。在此基础上，我们通过在随机选择的测量基础上对密钥进行编码来提出我们的方案：相位正交 (X) 或幅度正交 (P)，以稍微削弱协调效率和信道过量噪声的影响比较到目前的 UCVQKD 协议。新协议旨在简化以往一维协议的解码过程，同时保证量子通信的安全性。
