Random number generation is a critical security element in today's connected world to ensure our safety and trusted communications. While today's systems like Pseudo Random Number Generators (PRNGs) rely on deterministic - thus predictable - algorithms, Quantum RNGs exploit elementary quantum optic processes that are fundamentally probabilistic to produce true randomness. Thus, as we enter the quantum decade, Quantum Random Number Generation has established itself as the reference in terms of security, reliability, and ease-of-use.  With a variety of ways in which QRNGs can be produced, the photonics implementation appears to be the most promising strategy as it satisfies important requirements like an easy interfacing with communications protocols, high bit rates and increased security. The current proposal deals with a market study related to a new scheme of photonic QRNGs in which the efficiency of random bit generation can be scaled-up by cascading an increasing number of easy-to-realize fiber-based beam splitters and delay lines, while minimally increasing the device complexity. The implemented technique is highly versatile as it works independently from the source and the detection mechanism, while using, at the same time, simple, off-the-shelf telecommunications components in a time multiplexing scheme to increase the number of states a detected photon can occupy (thereby improving the randomness of the produced bits). Moreover, it provides a tunable control over both key performance parameters of commercial QRNGs (speed and security) in addition to being compatible with multiple integration/ free space/ fiber platforms. By improving photonic QRNGs performances, at a low-cost production, our new scheme opens the door to photonic QRNG commercial developments. Hence, we strongly believe that a market study for this innovative technology is extremely timely and will contribute to reinforce the impact of the high-technology Canadian industry on the international scene.

随机数生成是当今互联世界的关键安全要素，可确保我们的安全和可信通信。当今的伪随机数生成器 (PRNG) 等系统依赖于确定性（因此可预测）算法，而量子 RNG 利用基本概率性的基本量子光学过程来产生真正的随机性。因此，当我们进入量子十年时，量子随机数生成已成为安全性、可靠性和易用性方面的参考。  由于 QRNG 的生产方式多种多样，光子学实施似乎是最有前途的策略，因为它满足了重要的要求，例如与通信协议的轻松连接、高比特率和更高的安全性。 当前的提案涉及与光子 QRNG 新方案相关的市场研究，其中可以通过级联越来越多的易于实现的基于光纤的分束器和延迟线来提高随机位生成的效率，同时最大限度地增加设备复杂性。所实现的技术具有高度通用性，因为它独立于源和检测机制工作，同时在时间复用方案中使用简单的现成电信组件来增加检测到的光子可以占据的状态数量（从而提高产生位的随机性）。此外，除了与多个集成/自由空间/光纤平台兼容之外，它还提供对商用 QRNG 的关键性能参数（速度和安全性）的可调控制。 通过以低成本生产提高光子 QRNG 性能，我们的新方案为光子 QRNG 商业开发打开了大门。因此，我们坚信，针对这项创新技术的市场研究非常及时，并将有助于加强加拿大高科技产业在国际舞台上的影响力。
