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.

光学时钟是如此惊人，以至于它们在宇宙年龄的一秒钟内保持准确。将这些时钟从实验室带到田地，为电信，导航，传感和科学提供了绝佳的机会。英国世界一流的光时技术在学术界和国家计量学院（NPL）内为我们提供了在这项战略技术中领先地位的千载难逢的机会。有可能，我们希望抓住这个机会，并建立一个能够建立可部署世界上最先进的量子时钟的主权能力。我们将提供一个坚固且便携式的光学时钟，其准确性接近最佳的实验室时钟。我们的作品建立在过去的几个项目上获得的过去经验和专业知识。有可能的是，我们的铅将比当前的可运输系统小3倍，在3倍的体积中提供20倍的准确时钟。通过在伯明翰大学和国家计量学院（NPL）结合我们世界一流的团体的专业知识，这将是可能的。我们将通过与最终用户互动来证明我们的时钟对电信，地理和计量学的应用的有用性。
