PsiQuantum’s mission is to build the first useful quantum computers—machines capable of delivering the breakthroughs the field has long promised. Since our founding in 2016, our singular focus has been to build and deploy million-qubit, fault-tolerant quantum systems.
Quantum computers harness the laws of quantum mechanics to solve problems that even the most advanced supercomputers or AI systems will never reach. Their impact will span energy, pharmaceuticals, finance, agriculture, transportation, materials, and other foundational industries.
Our architecture and approach is based on silicon photonics. By leveraging the advanced semiconductor manufacturing industry—including partners like GlobalFoundries—we use the same high-volume processes that already produce billions of chips for telecom and consumer electronics. Photonics offers natural advantages for scale: photons don’t feel heat, are immune to electromagnetic interference, and integrate with existing cryogenic cooling and standard fiber-optic infrastructure.
In 2024, PsiQuantum announced government-funded projects to support the build-out of our first utility-scale quantum computers in Brisbane, Australia, and Chicago, Illinois. These initiatives reflect a growing recognition that quantum computing will be strategically and economically defining—and that now is the time to scale.
PsiQuantum also develops the algorithms and software needed to make these systems commercially valuable. Our application, software, and industry teams work directly with leading Fortune 500 companies—including Lockheed Martin, Mercedes-Benz, Boehringer Ingelheim, and Mitsubishi Chemical—to prepare quantum solutions for real-world impact.
Quantum computing is not an extension of classical computing. It represents a fundamental shift—and a path to mastering challenges that cannot be solved any other way. The potential is enormous, and we have a clear path to make it real.

Job Summary:
The technical lead for the single photon source validation will be responsible for successfully drive validation projects including the planning, the design of experiments and characterization of electro-optical assemblies based on single photon source generation optical circuits and superconductive single photon detectors.
Responsibilities:
- Lead the validation planning and define figures of merits and validation plans for the cryogenic electro-optical assemblies.
- Lead the development of algorithms to perform data analysis and extract key performance parameters.
- Lead the execution of the validation plans, including debugging and characterization the cryogenic electro-optical assemblies.
- Collaborate with cross-functional teams to review and provide feedback to the electro-optical assemblies design.
- Contribute to the bring up of laboratory cryogenic setups comprised of light sources, detector, switches; function generators, oscilloscopes, etc. to validate design functionality of the electro-optical assemblies in cryogenic environments.
