Quantum technology has the potential to have great impact upon various aspects of our daily lives. Across the UK National Quantum Technology Programme, work is underway to realise benefits to multiple sectors, for example within healthcare, transport, energy, communications and defence. One area within the programme is quantum sensing, where the UK National Quantum Technology Hub in Sensors and Metrology is creating the next generation of high performance sensors and aiming to bring these into everyday applications. These sensors are based upon the use of clouds of atoms as probes where, through the use of laser cooling (winning the Nobel prize in 1997), the atoms can be slowed down sufficiently that they are almost stationary during a measurement. This provides an extremely clean and well controlled sensor, allowing exceptionally precise measurements. For example, modern cold atom based clocks are stable enough that they would not drift by one second during the age of the Universe.The use of cold atoms also presents a challenge, as in order to create such as system requires high precision technology including stable and precise lasers and magnetic fields. This typically results in systems being large and complicated, traditionally filling an entire laboratory. Modern advances have allowed significant improvements in portability and size, but a considerable challenge still remains regarding power and driving electronics. The objective of the CONE project is to create compact and robust electronics for cold atom sensors, and trial their use in a demonstration system. The aim is to realise a 50% reduction in the overall system size, through both miniaturisation and better integration of the electronics. CONE aims to transfer knowledge to Red Wave Laboratories in order to enable them to fill an important gap within the UK quantum technology supply chain, enabling them to provide robust electronics solutions and potentially future integrated systems.

量子技术有可能对我们日常生活的各个方面产生重大影响。在整个英国国家量子技术计划中，正在努力实现多个部门的利益，例如医疗保健，交通，能源，通信和国防。该计划的一个领域是量子传感，英国国家量子技术传感器和计量中心正在创建下一代高性能传感器，并旨在将其应用于日常应用。这些传感器是基于使用原子云作为探针，通过使用激光冷却（1997年获得诺贝尔奖），原子可以被充分减慢，使它们在测量过程中几乎是静止的。这提供了一个非常干净和良好控制的传感器，允许非常精确的测量。例如，现代的冷原子时钟已经足够稳定，在宇宙时代不会漂移一秒。冷原子的使用也带来了挑战，因为为了创建这样的系统，需要高精度的技术，包括稳定和精确的激光和磁场。这通常导致系统庞大而复杂，传统上填满整个实验室。现代技术的进步使得便携性和尺寸有了显著的改进，但在功率和驱动电子设备方面仍然存在相当大的挑战。CONE项目的目标是为冷原子传感器创建紧凑而坚固的电子设备，并在演示系统中试用它们。其目标是通过电子设备的简化和更好的集成，实现整个系统尺寸减少50%。CONE旨在向Red Wave实验室转移知识，使他们能够填补英国量子技术供应链中的重要空白，使他们能够提供强大的电子解决方案和潜在的未来集成系统。
