Photonic quantum computing hardware and foundry services at room temperature
Quantum Computing Inc. manufactures photonic quantum processors and offers foundry services for thin-film lithium niobate (TFLN) chips, targeting room-temperature, low-power quantum systems. The tech stack is deep in FPGA simulation (ModelSim, Xilinx, Altera) and photonic design tools (Lumerical, Tidy3D, HFSS), with active projects spanning automated test procedures, firmware development (encryption, authentication), and TFLN component design — signaling a transition from prototype toward production-grade manufacturing. Pain points cluster around yield, fabrication scaling, and lab equipment procurement, reflecting a hardware company in the capital-intensive phase of moving from R&D to volume.
Quantum Computing Inc. (Nasdaq: QUBT) designs and manufactures quantum computing hardware based on integrated photonics, specifically thin-film lithium niobate platforms. The company operates at room temperature and low power, positioning its systems as more practical alternatives to traditional cryogenic quantum approaches. Beyond hardware, QCi offers foundry services for photonic chip production and targets applications in high-performance computing, AI, cybersecurity, and remote sensing. The organization spans 51–200 employees across engineering, operations, manufacturing, research, and product teams, headquartered in Hoboken, New Jersey.
