Our vision is to pioneer a mobile phone sized quantum navigator by combining chip-scale quantum clocks, accelerometers and rotation sensors (gyroscopes) that can be manufactured on silicon chips to be used for position, navigation and timing without reliance on signals from satellites. Our aim is to improve satellite-free navigator accuracy compared to present marine grade commercial systems by at least x10 with over a x100 reduction in size, weight, power and cost enabled through the development of new science approaches. An analogy is Harrison's pocket watch, H4, that won the Longitude Prize in 1773 as the small size reduced the uncertainties from temperature and acceleration drifts on navy ships.Society navigates using satnavs in vehicles and mobile phones but the nano-Watt signals are easy to jam, spoof and do not work inside buildings, under the ocean or underground. Spoofing and jamming are also used by pirates to steal ships, people traffickers and organised crime to hid illegal behaviour, and in military conflict zones to limit situational awareness of opponents.Resilient navigation without satellites uses dead reckoning where the current position from a previously determined reference is calculated using time, velocity, acceleration and rotation measurements. The UK Government recommends all position, navigation and timing for national security and critical national infrastructure can operate for greater than 3 days without updated references from satellites. The UK Government Blackett Review on Global Navigation Satellite Signals (GNSS) Dependencies and Vulnerabilities states that 5 days loss of satellite navigation has a potential loss of £5.2Bn to the UK economy.MOD, US DARPA, the European Defence Fund and the Connected Places Catapult indicates that national security and autonomous vehicle markets require far smaller, more accurate, robust and cheaper position, navigation and timing solutions such as the quantum chip-scale systems we proposed to develop. Connected and autonomous vehicles are predicted to create a £100 Bn global market for resilient position, navigation and timing systems with £2.7Bn GVA to the UK economy (>23,400 direct and 14,600 indirect UK jobs) by 2035. This research is key underpinning work to enable that market by developing UK supply chains with industry for practical position, navigation and timing systems.Quantum rotation sensors / gyroscopes have experimentally demonstrated drift stability performance 65 times better than optical gyroscopes with theoretical performance calculated to be 20,000 times better. Quantum accelerometers have experimentally demonstrated drift stability 4 orders of magnitude superior to classical accelerometers with hybrid systems also showing improvements of x80. At present these demonstrated quantum sensors are difficult to scale below 50 kg and something about the size of a washing machine. This project aims to take photonic integrated circuit and MEMS technologies to develop chip-scale atomic clocks, quantum rotation sensors / gyroscopes and quantum accelerometers to build much smaller and more practical quantum navigators that will have many applications and benefits to UK and global society.

我们的愿景是通过将芯片尺度量子钟，加速度计和旋转传感器（陀螺仪）（陀螺仪）结合起来，可以在硅芯片上制造，以用于位置，导航和时机，而无需释放卫星的信号，可以使用手机大小的量子导航器。我们的目的是将无卫星的导航器准确性提高至少X10，而X10的规模，重量，功率和成本降低了X10，通过开发新科学方法。哈里森的口袋手表H4在1773年获得了经度奖，因为小尺寸降低了海军船上的温度和加速饮料的不确定性。社交活动在车辆和手机中使用Satnavs进行导航，但纳米瓦特信号很容易驶入建筑物或在海洋中的建筑物内部工作。海盗还使用欺骗和干扰来窃取船只，贩运者和有组织的犯罪，以隐藏非法行为，并在军事冲突区域中限制了对选项的情境意识。没有卫星的无卫星导航使用死亡的估计，该估计估计使用时间，速度，速度，加速，加速度，加速度，加速度，加速和旋转量来计算当前确定的参考。英国政府建议在国家安全和关键国家基础设施的所有职位，导航和时机都可以运作超过3天，而无需更新的卫星参考。英国政府Blackett关于全球航行卫星信号（GNSS）依赖性和脆弱性的评论指出，卫星导航的5天损失可能损失52亿英镑的英国经济。我们建议开发的系统。预计预计将在2035年到英国经济（直接23,400和14,600英国的英国工作）创建一个100亿英镑的全球市场，用于赤字职位，导航和定时系统，到2035年，英国经济为27亿英镑（> 23,400个直接和14,600英国的工作）。这项研究是由与行业的供应链开发出来的关键基础工作，以使其供应链接，以实现英国的供应链，并旋转旋转式，导航和Timing timing Systemss.实验表明的漂移稳定性性能是光学陀螺仪的65倍，理论性能高20,000倍。量子加速度计在实验上证明了漂移稳定性的4个数量级，高于与经典加速度计的混合系统，也显示了X80的改进。目前，这些证明的量子传感器难以缩放50千克以下，并且关于洗衣机的大小。该项目旨在采用光子集成电路和MEMS技术来开发芯片尺度原子钟，量子旋转传感器 /陀螺仪和量子加速度计，以构建更小，更实用的量子导航器，这些导航器将对英国和全球社会具有许多应用和好处。
