rand()函数属于伪随机数生成器（Pseudo Random Number Generator，简称PRNG）。它通过使用一个初始种子值，经过特定算法生成一系列看似随机但实际上具有一定规律的数值。2.2 线性同余生成器（LCG） rand()函数是一种基于线性同余生成器（Linear Congruential Generator，简称LCG）的PRNG实现。LCG使用一个递推公式，每次迭...

量子随机数生成器(Quantum Random Number Generator,QRNG)是一种利用量子物理学原理产生真正的随机数的设备。与传统的伪随机数发生器不同,量子随机数生成器产生的数字序列是完全随机的,没有任何可预测性和规律性。 量子随机数发生器的原理是基于量子力学中的概率性本质,即测量结果的不确定性。在量子力学中,微观粒子(...
