介绍了基于等角球码的量子密钥分配协议，研究了它们在拦截/重发攻击下的行为。这样的协议提供了更大范围的安全噪声容限和速度选择比基于其堂兄弟，相互无偏基地的协议，同时也使确定thechannel噪声率，而不需要牺牲关键位。对于给定维度上的固定数量的信号状态，球形码协议以较慢的密钥生成速率为代价，为Alice和Bob提供了更多的噪声容忍度。
Quantum key distribution protocols based on equiangular spherical codes are introducedand their behavior under the intercept/resend attack investigated. Such protocols offera greater range of secure noise tolerance and speed options than protocols based ontheir cousins, the mutually-unbiased bases, while also enabling the determination of thechannel noise rate without the need to sacrifice key bits. For fixed number of signalstates in a given dimension, the spherical code protocols offer Alice and Bob more noisetolerance at the price of slower key generation rates.
