Quantum Architect, Simulation & Software

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:

Quantum architects research and develop architectures for fault tolerant photonic quantum computers, in particular methods for entanglement generation and error correction. Quantum architects in the Simulation team focus on building and running simulations to evaluate the performance of such methods and their integration into a full stack architecture. We are looking for a research software engineer or computational physicist to drive the development of the internal software tools and computational techniques used in our simulation efforts, in close collaboration with other technical teams. 

Responsibilities:

• Design, develop, and maintain software tools and infrastructure for the simulation of quantum architectures .
• Work closely with domain experts to explore and develop new ideas. 
• Ensure the interoperability of simulation tools and modeling frameworks across projects, teams and departments.
• Profile simulation tools and explore and implement more optimal numerical and computational techniques.
• Run numerical analyses, manage data, and communicate results. 

Experience/Qualifications:

• A Masters or PhD degree in Physics, Quantum Information, or a related field is required. 
• 3+ years of collaborative software engineering experience, preferably in an industry R&D environment. Knowledge of Python plus a lower-level language is preferred.
• Proven team player with an ability to collaborate effectively across departments, sites, and time zones.
• Ability to work independently, prioritize and steer projects to completion, and contribute to a fast-moving start-up environment. 
• Experience with numerical simulation techniques, e.g. Monte Carlo methods.
• Experience with collaborative software development tools and best practices e.g. Gitlab, CICD.
