Photonic quantum computers and integrated optics foundry services

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

Quantum Computing Inc. manufactures photonic quantum systems and thin-film lithium niobate (TFLN) optical components, operating at room temperature with low power consumption. The tech stack reveals a hardware-software co-design operation: FPGA tooling (Xilinx, Altera, Intel), simulation software (Lumerical, Tidy3D, HFSS), and C++/Python runtime development sit alongside physics modeling and manufacturing process control. Active projects span algorithm–hardware co-design, lidar applications, and optimization runtime layers—indicating a transition from pure quantum research toward productized systems. Pain-point clustering (simulation-to-fab misalignment, manufacturability constraints, process deviation) shows the core friction is closing the gap between design intent and physical yield.
