We experimentally demonstrate Tb/s fast random bit generation from random signals generated in a broadband random optoelectronic oscillator. The broadband random optoelectronic oscillator is used as photoelectron entropy source to generate wideband random signal. We sample the random waveform with a resolution of 10 bits and a sampling rate of 128 GS/s. All 10 bits can be preserved and a generation rate of 2.5 Tb/s (128 GS/s ×\times 10 bits ×\times 2 data) is achieved by using time-shift bit-order-reverse bitwise exclusive-or operation as a more complicated post-processing method. The randomness of random bit sequences is verified by using NIST Special Publication 800–22 statistical tests.

基于宽带随机光电振荡器的Tb/s快速随机比特生成


我们通过实验证明了从宽带随机光电振荡器中生成的随机信号生成 Tb/s 的快速随机位。宽带随机光电振荡器作为光电子熵源产生宽带随机信号。我们以 10 位分辨率和 128 GS/s 采样率对随机波形进行采样。通过使用时移位序反转按位异或运算，可以保留所有 10 位，并且生成速率为 2.5 Tb/s（128 GS/s ×\times 10 位 ×\times 2 数据）更复杂的后处理方法。随机比特序列的随机性通过使用 NIST Special Publication 800-22 统计测试来验证。
