I. Introduction
Generation of random numbers based on quantum processes is one of the most important and important tasks of cryptography [1], [2]. In the scheme of optical pumping and resonance detection, only two types of noise are fundamentally quantum in nature – the fractional noise of light and the quantum noise of an atomic ensemble [3]–[6]. It is known that the quantum phase noise of an atomic ensemble has a Gaussian probability distribution law [6]. Therefore in quantum random number generators (QRNG) use a special means of enhancing entropy – a quantum extractor. The initial sequences of random numbers after the QRNG extractor successfully pass the DIEHARD and NIST STS statistical tests [7].
