Job description
Quantum computing holds the promise of humanity’s mastery over the natural world, but only if we can build a real quantum computer. PsiQuantum is on a mission to build the first real, useful quantum computers, capable of delivering the world-changing applications that the technology has long promised. We know that means we will need to build a system with roughly 1 million qubits that supports fault tolerant error correction within a scalable architecture, and a data center footprint.
By harnessing the laws of quantum physics, quantum computers can provide exponential performance increases over today’s most powerful supercomputers, offering the potential for extraordinary advances across a broad range of industries including climate, energy, healthcare, pharmaceuticals, finance, agriculture, transportation, materials design, and many more.
PsiQuantum has determined the fastest path to delivering a useful quantum computer, years earlier than the rest of the industry. Our architecture is based on silicon photonics which gives us the ability to produce our components at Tier-1 semiconductor fabs such as GlobalFoundries where we leverage high-volume semiconductor manufacturing processes, the same processes that are already producing billions of chips for telecom and consumer electronics applications. We also benefit from the quantum mechanics reality that photons don’t feel heat or electromagnetic interference, allowing us to take advantage of existing cryogenic cooling systems and industry standard fiber connectivity.
In 2024, PsiQuantum announced two government-funded projects to support the build-out of our first Quantum Data Centers and utility-scale quantum computers in Brisbane, Australia and Chicago, Illinois. Both projects are backed by nations that understand quantum computing’s potential impact and the need to scale this technology to unlock that potential. And we won’t just be building the hardware, but also the fault tolerant quantum applications that will provide industry-transforming results.
Quantum computing is not just an evolution of the decades-old advancement in compute power. It provides the key to mastering our future, not merely discovering it. The potential is enormous, and we have the plan to make it real. Come join us.
There’s much more work to be done and we are looking for exceptional talent to join us on this extraordinary journey!
Job Summary:
Our system architecture team sits at the interface of hardware development, manufacturing, and the quantum architecture to design the first fault-tolerant quantum computer. We are looking for a physicist to drive the efforts of developing internal tools for designing and analyzing the system architecture in close collaboration with other technical teams as well as modelling the networked system architecture of our upcoming systems.
Responsibilities:
- Contribute to our Quantum Computing system architecture and software system roadmap.
- Maintain graph-based models of the system architectures of our upcoming systems.
- Analyze and optimize flow of classical and quantum information inside networked system architectures requiring a large amount of just-in-time decisions to route photonic qubits.
- Profile the planned systems by using system models and derive performance metrics.
- Design and develop software tools and infrastructure to enable development, analysis and tracking of our quantum system architectures.
Experience/Qualifications:
- Degree in Physics and a strong background in quantum information theory, quantum computing, or quantum communication networks.
- Experienced in working with stabilizer states and ZX-calculus.
- Proficiency in Python.
- 3+ years of experience in software development, with an emphasis on scientific computing.
- Ability to collaborate effectively across departments, sites, and time zones.
- A hands-on mentality to own challenges and develop solutions independently.
- Competent use of collaborative software development tools (e.g., GitLab) is desirable.
