Pioneering quantum light source technology from device to module, advancing the quantum revolution.
NantQ was founded on a singular vision: to make high-quality entangled photon sources available as reliable, engineered products rather than fragile laboratory setups. We believe that the quantum technology revolution — from unhackable communications to exponentially faster computing — depends on robust, reproducible sources of quantum light.
Our vertically integrated approach spans the entire value chain: from growing and poling lithium niobate crystals, through waveguide fabrication and fiber packaging, to complete turnkey systems with integrated electronics and software.
As the pioneer of quantum light source commercialization, NantQ serves researchers, system integrators, and end-users across quantum computing, sensing, and secure communication networks worldwide.
We control every step from crystal growth to system calibration. This ensures consistency, performance, and the ability to customize at any level of the stack for our customers' unique requirements.
Every product ships with measured performance data — spectral profiles, heralding efficiencies, and visibility measurements. We publish what we measure and guarantee what we publish.
We don't just sell components — we engineer solutions. Our team works alongside customers to select, configure, and optimize the right quantum source for each specific application and deployment scenario.
NantQ founded with the mission to commercialize PPLN-based entangled photon sources, bridging the gap between laboratory demonstrations and deployable products.
Released the first commercial PPLN Ti-diffusion waveguide SPDC chips with Type-II phase matching, enabling researchers worldwide to build custom entangled photon setups.
Introduced temperature-stabilized SPDC modules and precision TEC controllers, making quantum light sources plug-and-play for the first time.
Launched the flagship quantum entangled photon light source system with integrated touchscreen monitoring, achieving V = 0.96 visibility — setting a new benchmark for commercial quantum sources.
Extended the product line with visible-band and 775 nm phase modulators, plus complete development kits enabling rapid adoption of quantum photonics in new research groups and institutions.
In-house PPLN fabrication with custom poling periods
Ti-indiffusion process for single-mode LiNbO₃ waveguides
Factory-aligned PM and SMF pigtailing with hermetic sealing
Custom TEC controllers, LCD interfaces, and instrument drivers
Complete quantum light source systems with real-time monitoring
Tailored wavelength, bandwidth, and packaging configurations
NantQ quantum photon sources and components are deployed in research institutions, defense labs, and quantum-technology companies across Asia, Europe, and North America. Our products serve as building blocks for the quantum internet infrastructure being developed worldwide.
