Quantum Computing Inc. Tech Stack

Photonic quantum computing hardware and foundry services at room temperature

Computer Hardware Manufacturing Hoboken, New Jersey 51–200 employees Founded 2018 Public Company

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.
