Job description

PsiQuantum’smission 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 approachisbased on silicon photonics. Byleveragingthe 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: photonsdon’tfeel heat, are immune to electromagnetic interference, and integrate with existing cryogenic cooling and standard fiber-optic infrastructure.

In 2024,PsiQuantumannounced 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.

PsiQuantumalso 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. Itrepresentsa fundamental shift—and a path to mastering challenges that cannot besolvedany other way. The potential is enormous, and we have a clearpathto make it real.

Come join us.

Job Summary:

Our system architecture department sits at the interface of hardware development, manufacturing, and the quantum architecture to design the first fault-tolerant quantum computer. The optical architecture group are specifically responsible for:

• discovering and developing new schemes for photonic quantum computation
• translating abstract quantum information protocols into the designs of physical systems
• modelling quantum optical systems to determine the requirements for hardware systems

Internships are hired on a rolling basis, with durations of 3 to 6 months. We offer placement opportunities in Palo Alto, California (United States), Bristol (United Kingdom), and remotely.

The internship role requires a challenging mix of analytical skills and programming. We are looking for fast learning, productive, creative individuals who are motivated to translate theoretical concepts into real technology.

Responsibilities:

• Contribute to ongoing optical architecture technical projects. For example:
  • Writing prototype software implementations for controlling and simulating the optical networks inside photonic quantum computers.
  • Applying results from quantum information theory, network design and/or optimization to improve optical architecture designs.
  • Development and discovery of new approaches to photonic quantum computing.
• Simulate and benchmark different protocols.
• Document and communicate results.

Experience/Qualifications:

• Degree in: Physics, Math, Computer Science, Engineering or equivalent.
• Currently studying or recently finished a postgraduate degree (PhD preferred).
• Experience in programming in Python, C++, Julia or similar languages.
• Competent use of collaborative software development tools (e.g., GitHub) is desirable.
• Ability to communicate effectively and work closely with others.
• Preferred: knowledge of quantum optics, photonic hardware, switch network design, optimization, graph theory.
