FEMTO 2ND - Femtosecond Measurement Technology Options

飞秒计划(比如“飞秒”，也就是十亿分之一秒的百万分之一秒！)这是英国五年计划的关键一步，该计划旨在将非凡的量子物理新概念从研究实验室带入日常生活。Chronos技术公司、TMD技术公司和巴斯大学的工程和物理系已经联手使用一种名为“中空纤芯纤维(HCF)”的新技术来制造这些系统的关键部件。他们正在开发创新技术，这些技术是量子钟的基石。这一旅程的下一阶段将交付第一个充满Rb的HCF物理包的原型，以期进展到一个原型量子钟。不久，量子钟将开始保护我们的电信和广播系统，因为它们的关键时间同步现在是从脆弱的卫星获取的，由于干扰、干扰或太空天气风暴而丢失。这些新的时间和频率量子物理来源承诺了以前无法想象的飞秒精度。最终，它们还可能帮助英国为陆地、海洋、空中和太空提供超精密导航，以及包括重力望远镜在内的全新应用。

Project FEMTO-2ND (say "femtosecond", which is a millionth of a billionth of a second!) is a key step in the UK’s 5-year programme to bring the remarkable new concepts of quantum physics out of research labs and into the everyday world. Chronos Technology, TMD Technologies and the University of Bath’s Engineering and Physics Departments have teamed up to create the key components of these systems by using the new technique called "hollow core fibre (HCF)". They are developing the innovative technologies that are the building blocks of Quantum Clocks. This next stage in the journey will deliver the first prototype Rb filled HCF physics packages with a view to progressing to a prototype quantum clock. Soon Quantum Clocks will begin to protect our telecommunications and broadcasting systems when their critical time synchronisation, now taken from vulnerable satellites, is lost to interference, jamming or space weather storms. These new quantum physics sources of time and frequency promise the femtosecond accuracies previously unimaginable. Eventually, they may also help the UK deliver ultra-precise navigation for land, sea, air and space plus wholly new applications, including a gravity telescope.
