UK- based startup developing ultra-compact, high-precision quantum optical sensors MoreLess

QLM Technology specializes in advanced quantum gas lidar systems designed for continuous monitoring and precise detection of greenhouse gas emissions. The company's core product leverages cutting-edge quantum technology to capture and locate emission sources in three dimensions, making it particularly effective at identifying 'super emitters'—the largest 5% of emission sources that contribute over 50% of total emissions. QLM Technology serves industries with significant greenhouse gas emissions, such as oil and gas, waste management, and industrial manufacturing. Operating in the environmental technology market, QLM Technology employs a subscription-based business model, offering its monitoring solutions through a combination of hardware sales and recurring software subscriptions for data analytics and reporting. Revenue is generated from the sale of the quantum gas lidar units, installation services, and ongoing subscription fees for access to the QLM Cloud platform, which provides advanced administrative tools, alerts, and reporting functionalities. The company's innovative approach not only helps clients comply with environmental regulations but also enables them to proactively manage and reduce their carbon footprint.

Keywords: Quantum Gas Lidar, greenhouse gas emissions, continuous monitoring, 3D detection, super emitters, environmental technology, oil and gas, waste management, industrial manufacturing, QLM Cloud.
