Quantum Computing Inc. develops quantum computing systems and photonic technologies for optimization, machine learning, sensing, imaging, and cybersecurity applications using integrated photonics and non-linear quantum optics. The company's flagship product is the Entropy Quantum Computer, which operates at room temperature with low power consumption by leveraging photonic architecture and environmental effects rather than competing cryogenic approaches. QCi generates revenue from quantum computing machines, optical chips for quantum information processing and sensing, AI-enabled edge computing devices, LIDAR and imaging systems, cybersecurity solutions, and foundry services, while competing in a crowded landscape against technology giants and specialized quantum startups by offering photonic-based approaches with advantages in size, weight, power efficiency, and cost.
