Photonic quantum computers and integrated optics foundry services
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.
Quantum Computing Inc. (Nasdaq: QUBT) designs and manufactures photonic quantum computers and integrated photonics components based on thin-film lithium niobate technology. Founded in 2018 and headquartered in Hoboken, New Jersey, the company operates as a vertically integrated photonics and quantum optics firm with in-house fabrication and custom electronics development. The product portfolio targets high-performance computing, optimization, artificial intelligence, and cybersecurity applications, with additional revenue from a foundry service model for photonic chip production. Recent acquisition of Luminar Semiconductor expanded manufacturing capacity and component subsystem offerings. The 51–200 person organization is weighted toward engineering and research roles, reflecting the capital intensity of quantum hardware development and the ongoing challenge of translating simulation results into manufacturable designs.
QCi's core stack includes FPGA design tools (Xilinx, Altera, Intel), physics simulation software (Lumerical, Tidy3D, HFSS), C++/Python for runtime development, and embedded Linux on ARM. Manufacturing and process simulation use SAP, ModelSim, and SystemVerilog.
Active projects include photonic quantum and classical platform development, algorithm–hardware co-design, C++ runtime and HAL layers for photonic optimization, large-scale optimization software, lidar experiments, and simulation-to-fabrication tooling to reduce design-fab misalignment.
