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. 

Come join us. 

Job Summary:

We are looking for enthusiastic candidates interested in applying quantum computing to real-world challenges. At PsiQuantum, we are particularly focused on use cases of quantum computing in chemistry, drug design, materials science, and fluid dynamics. Along these lines, we are offering internships in the areas of quantum algorithms and quantum compilation.

Your work could entail the - 

• Development of quantum algorithms to solve impactful problems,
• Optimization of ubiquitous subroutines in fault tolerant quantum algorithms,
• Compilation of quantum algorithms to logical gate sets,
• Incorporation of architecture-aware optimizations,
• Estimation of quantum resources.

Prior work in the field of fault tolerant quantum algorithms and compilation is preferred, but enthusiasm for quantum computing is essential.

Desired experience and skills:

• Currently studying for, or completed a postgraduate degree related to quantum algorithms, quantum circuit compilation, fault tolerance or another aspect of quantum computing OR 5+ years working professionally in one or more of these fields. 
• Experience with programming languages (e.g. Python) and collaborative software development tools (e.g. Git).
• A creative and adaptable approach to problem solving.
• Ability to work effectively in a highly collaborative team.
