“…The conclusion is that molecular fluctuations grow as the largest Lyapunov exponent, implying that some after some time the uncertainties in the macroscopic variables are as large as the variables themselves. These results imply that the usual deterministic description is inadequate for chaotic systems and some experimental results 5 have confirmed that molecular fluctuations may have this dramatic effect.…”

In this work the effects of molecular or intrinsic fluctuations on some models of coupled chemical reactions exhibiting low-dimensional deterministic chaos are investigated. The study is performed by considering the system at the mesoscopic level, namely by stochastically simulating the corresponding chemical master equation. Two specific models are studied: the isothermal three-variable autocatalator of Peng et al. and a chemical version of Rössler's model of spiral chaos. The main conclusions are that the corresponding strange attractors obtained in these models are robust against fluctuations, although when the system is near the onset of chaos the presence of fluctuations may anticipate the appearance of chaos.

“…This uncertainty continuously scrambles the least significant bits of the state of the system, continuously re-seeding the chaotic system. The noise is amplified by the chaos [35,36] and contributes to the entropy production. In the case of laser chaos, the intrinsic noise has been considered to be quantum mechanical in origin and due to spontaneous emission in the laser [83].…”

“…Chaotic systems amplify uncertainties in initial conditions and sources of intrinsic noise [35,36]; only in the last decade has this inherent unpredictability been harnessed for random number generation in the form of chaotic lasers [18,[37][38][39][40][41][42][43][44][45]. For a review of chaotic lasers including their applications to RNGs, see ref.…”

The never-ending quest to improve the security of digital information combined with recent improvements in hardware technology has caused the field of random number generation to undergo a fundamental shift from relying solely on pseudo-random algorithms to employing optical entropy sources. Despite these significant advances on the hardware side, commonly used statistical measures and evaluation practices remain ill-suited to understand or quantify the optical entropy that underlies physical random number generation. We review the state of the art in the evaluation of optical random number generation and recommend a new paradigm: quantifying entropy generation and understanding the physical limits of the optical sources of randomness. In order to do this, we advocate for the separation of the physical entropy source from deterministic post-processing in the evaluation of random number generators and for the explicit consideration of the impact of the measurement and digitization process on the rate of entropy production. We present the Cohen-Procaccia estimate of the entropy rate h( , τ ) as one way to do this. In order to provide an illustration of our recommendations, we apply the Cohen-Procaccia estimate as well as the entropy estimates from the new NIST draft standards for physical random number generators to evaluate and compare three common optical entropy sources: single photon time-of-arrival detection, chaotic lasers, and amplified spontaneous emission. arXiv:1612.04415v3 [physics.optics]
