Quantum Computing Internship Jobs in California (NOW HIRING)

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 seeking a motivated and detail-oriented intern to support the Optical Packaging Process team. This is an entry-level role ideal for students interested in semiconductor, photonics, or manufacturing processes. The intern will assist with documenting processes, organizing experimental data, and supporting simple laboratory experiments under supervision.

Responsibilities:

• Assist in drafting, editing, and formatting SOPs and work instructions.
• Organize and maintain process documentation and version control.
• Support engineers in summarizing design of experiments (DOE) results.
• Help prepare clear data summaries, tables, and basic visualizations.
• Assist in executing simple, well-defined experiments under guidance.
• Record experimental results accurately and maintain lab notes.
• Contribute to continuous improvement of documentation and workflows.

Experience/Qualifications:

• Currently pursuing a Bachelor's degree in Engineering, Physics, Materials Science, or a related field.
• Strong attention to detail and organizational skills.
• Ability to follow instructions and work collaboratively in a team environment.
• Prior internship or lab experience is a plus but not required.
