For the UK to reach a net-zero carbon economy, the regulation and limitation of greenhouse gas (GHG) emissions needs to rapidly expand. Natural gas is fast becoming our most dominant fossil fuel and industrial leaks are now a leading source of GHG emissions. Industry majors have committed to expanding emissions monitoring, but the technologies currently available are expensive, labour intensive, and inaccurate. Quantum Gas Imaging (QGI), invented by QLM, is an emerging technology that uses non-cryogenic Shortwave Infrared (SWIR) Single-Photon Avalanche Detectors (SPADs) to demonstrate innovative and highly sensitive long-range, single-photon lidar gas imagers that locate and measure invisible gases including methane, CO2 and more.The current generation of the QGI camera uses mechanical scanning to analyse an area with a single sensor. This limits the data acquisition rate, thus prohibiting fast mobile deployment, in the interest of maintaining the sensitivity and spatial resolution necessary. Commerical-off-the-shelf (COTS) SPAD arrays can allow for non-mechanical scanning, but current readout electronics are limited in throughput to allow for such developments. SWIR SPAD array readouts, such as these, require high-speed data acquisition. When combined with the flexibility of Field-Programmable Gate-Array (FPGA) technology, this is going to be a key enabling technology for all other photonic 2nd generation quantum technologies based on single-photon quantum optics research, including free-space quantum telecommunications, photonic quantum processors, and lidar.In this project, QLM Technology will develop a non-mechanical scanning QGI camera that exploits SPAD arrays and their high throughput capabilities to achieve state-of-the-art acquisition rates, sensitivity, and large detector dynamic range. Aston University will develop the advanced signal processing algorithm required to achieve high speed real-time Time to Digital Converter (TDC) and Time-Correlated Single Photon Counting (TCSPC) on FPGAs and utilises multi-photon information for the formation of the correlations. RedWave will build the electronics platform to incorporate the advanced high speed time tagging capability into new standalone products, which can be applied in other fields for the 2nd generation quantum technology used in life science and free-space communications, thanks to the flexibility of the FPGA based system.

要使英国达到零碳经济，温室气体（GHG）排放的法规和局限性需要迅速扩大。天然气正迅速成为我们最主要的化石燃料，工业泄漏现在已成为温室气体排放的主要来源。行业专业的专业致力于扩大排放监控，但目前可用的技术昂贵，劳动密集型和不准确。 QLM发明的量子气成像（QGI）是一项新兴技术，它使用非晶型短波红外（SWIR）单光雪崩检测器（SPADS）来展示创新且高度敏感的远距离远程和高度敏感的单光子liDar liDar气体成像器，以示例和测量Invisible Goses scan coen coen coen，以及scan coen con coen，以及Qan con的co2 co2，以及scan coy2，以及co2 co2 co2 co2 co2 scan coy2及其co2 co2 cos2和更多的镜头。用单个传感器分析区域。这限制了数据采集率，因此禁止快速移动部署，以维持所需的灵敏度和空间分辨率。商业式上搁置（COTS）SPAD阵列可以允许非机械扫描，但是当前的读数电子设备在吞吐量上受到限制以进行此类发展。 SWIR SPAD阵列读数（例如这些）需要高速数据采集。当结合现场可编程登机阵列（FPGA）技术的灵活性时，这将是基于单光子量子量子光学研究的所有其他光子第二代量子技术的关键启用技术，包括自由空间量子量子电信，包括QLM机能，并开发QLM机能，并开发出QLM的QLMICHIC，并扫描QLM机。它们的高吞吐量能力可实现最新的采集率，灵敏度和较大的检测器动态范围。阿斯顿大学（Aston University）将在FPGA上开发高级实时到达数字转换器（TDC）和时间相关的单光子计数（TCSPC）所需的先进信号处理算法，并利用多光子信息来形成相关性。 RedWave将构建电子平台，将高级高速时标记功能纳入新的独立产品中，这可以在其他基于FPGA的系统的灵活性中用于生命科学和自由空间通信中第二代量子技术。
