Quantum Architect, Simulation & Error Modeling

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:

The quantum architecture team at PsiQuantum develops and evaluates high-level designs for fault-tolerant photonic quantum computers. It is critical that these designs are evaluated using models that capture all important sources of error without precluding simulation of large-scale systems. We are expanding our team that develops and refines these models.   

The ideal candidate will have a background in physics with some exposure to quantum information, quantum error correction and quantum optics. Proficiency with Python (or similar) and experience managing codebases is required.  

Responsibilities:

• Work closely with domain experts to model quantum phenomena in photonic components, circuits, and devices.
• Implement controlled approximations of models for integration into large-scale simulation frameworks.
• Identify sources of error, interactions with quantum error correcting codes, and potential mitigation techniques.
• Profile simulation tools and explore and implement more optimal numerical and computational techniques.
• Run numerical analyses, manage data, and communicate results. 

Experience/Qualifications:

• Degree in Physics, Math or Computer Science or equivalent required. PhD in Physics, Math or Computer Science, with a focus on quantum information theory or quantum computation preferred.
• Ability to collaborate effectively across departments, sites, and time zones.
• Ability to work independently and contribute in fast-moving start-up environment.
• Experience programming in Python, C++ or similar languages.
• Experience with numerical simulation techniques e.g. Mmarkov-chain Monte Carlo or tensor networks.
• Competent use of collaborative software development tools (e.g., GitHub) is desirable.
