Lianggan Intelligence raises tens of millions in angel round, quantum sensing for inertial navigation and gas monitoring

Founded in September 2023 and incubated by SJTU's Quantum Sensing Institute, Lianggan Intelligence raised an angel round led by Futeng Capital (Shanghai State Investment) with Liuhu Venture Capital. The company focuses on photonic quantum enhancement, offering multi-grade quantum navigation devices (including a grain-sized micro optical quantum gyroscope with navigation-grade accuracy) and electric power quantum gas monitors (CNAS-certified, purchased by a grid company). Currently in small-batch trial production, it has delivered to grid companies and aerospace institutes. The core advantage of photonic quantum enhancement is room-temperature operation without changing supply chains or usage habits, directly amplifying weak signals and suppressing noise. This lowers deployment barriers for quantum sensors in inertial navigation and gas monitoring. For grid companies and aerospace users, quantum gyroscopes improve accuracy while shrinking size, meeting all-weather monitoring and unmanned equipment needs; gas monitors aim to break foreign monopolies in high-voltage equipment monitoring. The company plans to evolve toward 'quantum sensing-computing' to build quantum intelligent sensors.
