Job Description:

We believe quantum computing will change everything. It will have the power to transform the foundations of giant industries that rely on intensive computation. PsiQuantum is on a mission to build the world's first useful quantum computer, capable of delivering these transformative results. We know that means it will need 1 million qubits, error correction, 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 is uniquely positioned to deliver on the promise of quantum computing years earlier than our competitors. Our architecture is based on photonics which gives us the ability to produce our components using existing high-volume semiconductor manufacturing processes, the same processes that are today producing billions of chips for telecom and consumer electronics applications. Since photons don't feel heat, we can take advantage of existing cryogenic cooling systems, the kind that have been operating at facilities like the Stanford Linear Accelerator (SLAC). And because photons are in fact light, they can move between subsystems at tremendous speed using standard fiber connectivity.Our team is building a utility scale quantum computer and the software tools needed to build fault tolerant quantum applications. We're a highly motivated and collaborative group focused on a singular goal - building the world's first useful quantum computer on the fastest path possible.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 applications architects drive research and development of quantum algorithms and lead partnered collaborations on the application of quantum algorithms to real-world computational problems. The applications team is fully focused on algorithms in the fault tolerant regime and is very tightly integrated with quantum architecture development. The scope of the quantum applications team includes development of new quantum algorithms and methods, scoping of use-cases, simulation and analysis of resource requirements, optimization of compiling methods and development of methods for universal fault tolerant logic.This role is specifically focused on the isolation of applications for quantum computers and the development of quantum algorithms for fault-tolerant quantum computers. The architect will translate computational tasks into abstract specifications for quantum algorithms, understand their asymptotic performance, work to define post-classical problem instances, and collaborate with the compilation team to build explicit instantiations of said algorithms.Responsibilities:

• Research and development of quantum algorithms tailored for fault-tolerant quantum computers, particularly around differential equations.
• Work closely with external partners to instantiate, validate and optimize quantum algorithms for use cases across domains in this category, such as in fluids and plasma physics. Establish benchmarks and problem instances to validate post-classicality of quantum algorithms.
• Simulation and analysis of resource requirements for fault tolerant implementation of quantum algorithms in photonic quantum computing.
• Collaborate with quantum architecture group to co-optimize algorithm methods with architectural design.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.
  • 3+ years of relevant academic or industry research experience in quantum algorithms, quantum applications or quantum circuit compilation preferred.
  • Experience with quantum algorithms and compiling in the regime of fault tolerant gates preferred.
  • Experience working with partners in academia or industry to analyze real-world quantum applications of interest preferred.
  • Proven team player with an ability to work effectively across departments, sites and time zones.
  • Ability to work independently and contribute to fast-moving start-up environment.
  • Experience programming in Python, C++ or similar languages.PsiQuantum provides equal employment opportunity for all applicants and employees.
