Quantum technologies will transform and improve crucial aspects of our life. To name a few, they will protect our privacy, and secure digital communications from any cyber attack, push the speed of computers to new levels, enable imaging the faintest objects, with applications to security and healthcare.While few of these outcomes are moving towards commercialisation, such as quantum-secured communications, others are still far from being a robust technology. The UK government has invested substantial resources in promoting the translation of the science available in academic institutions into technologies for the benefit of the public. For this quantum revolution to happen, we need to combine the know-how available in the academia, the technical capabilities of our high-tech companies, and the feedback from potential users of the technology.With this proposal, we are following this receipt, targeting the development of the first commercial source of visible, entangled photons, suitable for applications ranging from secure communication to metrology. Entangled light is the key to unlock the possibilities offered by quantum mechanics, and is the starting point for many applications, such quantum-key distribution and quantum computing. The components required to build an entangled light source are a laser and a suitable crystal that converts the laser light into entangled photons. Chromacity is a UK leader in the market of laser systems while Covesion is a world leader in the supply of crystals for the generation of entangled photons. We propose therefore to partner with these companies bringing our know-how in quantum optics. The University of Glasgow is indeed a leading institution in the UK, and the world, for what concern quantum optics and quantum technologies. Together, we have the production capabilities, the engineering skills, and the supply chain, to bring a visible source of entangled photons on the market. The role of the academic team in this project is twofold. On the one hand, we shall guide the design of the optical components required to generate the entangled states, starting from the technology provided by the two partner companies. We shall exploit our experience in the generation of entangled states in a lab to inform the two companies on the best choice of the nonlinear crystals parameters, the geometry of the laser interaction with the nonlinear elements, and on the proper measurement procedure required to quantify the level of entanglement achieved. This will be, therefore, a knowledge transfer action, aimed at bringing the academic know-how into a commercial reality. On the other hand, we will test the results produced by the joint work of Chromacity and Covesion. In this scenario, the University of Glasgow team will be the beta-tester. We are indeed end-users in the potential quantum-optical market since most of our research requires entangled states to be carried on. We shall, therefore, provide our feedback to the companies, concerning performances, packaging and user-friendliness. As the research in quantum optics becomes increasingly common in academia, a growing number of researchers will look for "plug and play" sources of entangled states.

量子技术将改变和改善我们生活的关键方面。仅举几例，它们将保护我们的隐私，并保护数字通信免受任何网络攻击，将计算机的速度推向新的水平，使成像最微弱的对象，并应用于安全和医疗保健。虽然很少有这些成果正在朝着商业化迈进，例如量子确定的通信，但其他结果仍然远离强大的技术。英国政府已经投入了大量资源来促进学术机构可用的科学翻译为技术，以使公众受益。为了使这次量子革命发生，我们需要结合学术界的专有技术，高科技公司的技术能力以及该技术的潜在用户的反馈。在此提案中，我们遵循此收据，针对可见的，纠缠的光子的首个商业来源，适用于从安全通信到安全通信到学分的应用。纠缠光是解锁量子力学提供的可能性的关键，并且是许多应用程序（例如量子键分布和量子计算）的起点。构建纠缠光源所需的组件是激光和合适的晶体，可将激光光转换为纠缠的光子。 Chromacity是激光系统市场上的英国领导者，而Covesion是供应纠缠光子的晶体供应的世界领导者。因此，我们建议与这些公司合作，将我们的量子光学技术专业化。格拉斯哥大学确实是英国和世界的领先机构，涉及量子光学和量子技术。我们共同拥有生产能力，工程技巧和供应链，以在市场上带来可见的纠缠光子的可见来源。学术团队在该项目中的作用是双重的。一方面，我们将指导从两家合作伙伴公司提供的技术开始，从而指导生成纠缠状态所需的光学组件。我们将利用我们在实验室中纠缠的州产生的经验，以告知两家非线性晶体参数的最佳选择，激光互动与非线性元素的几何形状以及量化达到纠缠水平所需的适当测量程序。因此，这将是一项知识转移行动，旨在将学术知识带入商业现实。另一方面，我们将测试由Chromitical和Covesion的联合工作产生的结果。在这种情况下，格拉斯哥大学团队将成为Beta-Tester。我们的确是潜在量子 - 光学市场中的最终用户，因为我们的大多数研究都要求继续进行纠缠的国家。因此，我们将向公司提供有关性能，包装和用户友好性的反馈。随着量子光学的研究在学术界变得越来越普遍，越来越多的研究人员将寻求纠缠状态的“插头”来源。
