Portable strontium lattice clock for ultra stability and long holdover (POSSIBLE)

光学钟是如此神奇，以至于它们在宇宙年龄的误差上保持在一秒以内。将这些时钟从实验室带到现场，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）的世界一流光学时钟技术为我们提供了在这一战略技术上占据领先地位的黄金机会。有了可能，我们希望抓住这个机会，建立一个主权能力，能够建造世界上最先进的量子时钟，可以在现场部署。我们将提供一种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的经验和专业知识的基础上，这些经验和专业知识是通过几个光学时钟项目获得的。在可能的情况下，我们将率先提供比当前可移动系统精确20倍的时钟，体积要小3倍。这将通过结合我们在伯明翰大学的世界级团队和国家计量研究所NPL的专业知识而成为可能。我们将展示我们的时钟在电信、大地测量学和计量学应用中的实用性，并通过与最终用户的接触。

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.
