This scheme does not require that Alice and Bob choose between alternative measurements, therefore improving the generating rate of key bits. At the same time, in this scheme detecting Eve requires the comparison of fewer bits.

- 此方案不需要建立密鑰的雙方Alice、Bob進(jìn)行測量基的選擇,同時(shí),檢測偷聽(tīng)者需要對比更少的量子位,所以提高了產(chǎn)生密鑰的效率。
