Optical clocks are so amazing that they remain accurate to within one second over the age of the universe. Bringing these clocks from the lab to fields offers great opportunities for telecommunications, navigation, sensing, and science. UK's world class optical clock technology within academia and national metrology institute (NPL) provide us with a golden opportunity to take a leading position in this strategic technology. With POSSIBLE we want to seize this opportunity and build up a sovereign capability able to build the world's most advanced quantum clocks which are field deployable. We will deliver a rugged and portable optical clock with an accuracy that approaches the best laboratory clocks. Our work builds upon the past experience and expertise gained through several projects on optical clocks. In POSSIBLE we take the lead and will deliver a 20x more accurate clock in a 3x smaller volume than the current transportable systems. This will be possible by combining the know-how of our world class groups at the University of Birmingham and national metrology institute, NPL. We will demonstrate our clock's usefulness to applications in telecom, geodesy and metrology, and by engaging with end users.

光学钟是如此令人惊叹，它们的精确度在宇宙年龄的1秒内保持不变。将这些时钟从实验室带到野外，为电信、导航、传感和科学提供了巨大的机会。英国学术界和国家计量研究所(NPL)的世界级光学时钟技术为我们提供了在这一战略技术方面处于领先地位的黄金机会。在可能的情况下，我们希望抓住这个机会，建立一种主权能力，能够建造世界上最先进的、可现场部署的量子钟。我们将提供坚固耐用的便携式光学时钟，其精度接近最好的实验室时钟。我们的工作建立在过去通过几个光学钟项目获得的经验和专业知识的基础上。在可能的情况下，我们将以比当前可移动系统小3倍的体积提供20倍的精度更高的时钟。通过将我们伯明翰大学的世界级团队和国家计量研究所NPL的技术结合起来，这将是可能的。我们将展示我们的时钟在电信、大地测量和计量方面的应用，并通过与最终用户接触来展示其实用性。
