Senior Theoretical Scientist (QEC)

We are pioneering advancements in quantum computing by utilising trapped ion technology and our proprietary laser-free quantum control methods. Our research and development efforts build on our fully integrated quantum processors that can be fabricated within standard silicon foundries. This unique approach allows us to leverage the highest-performing qubit technology while ensuring scalability and manufacturability using existing semiconductor fabrication technology. We approach quantum computing with a focus on minimising errors, striving to achieve ultra-low gate errors at scale. Our immediate objective is to develop functional quantum computers within the NISQ regime, aiming to construct fault-tolerant machines that require minimal QEC overhead. Our recent breakthroughs include achieving 99.97% fidelity in two-qubit gates and 99.9992% fidelity in single-qubit operations without error correction, setting new industry standards for performance. What to expect: You will play a pivotal part in shaping the future of our quantum computing systems by bridging the gap between theoretical research and practical implementation of quantum error correction (QEC). You'll work on developing QEC codes, simulation tools, algorithmic resource estimates and architectural designs that will directly influence the design and performance of our next-generation trapped ion quantum systems. What you'll be responsible for: You will play a key role in developing and refining the QEC strategies for our cutting-edge trapped-ion quantum computing systems. Your work will involve theoretical research and practical applications. Your responsibilities would include:

• QEC Research: Develop resource estimates for fault-tolerant quantum algorithms, build models and simulations to inform low-level system requirements, and design experiments to validate QEC methods in small-scale systems.
• Quantum Architecture: Create and optimise QEC codes for our trapped-ion architecture, providing insights that guide architectural decisions for our next-generation error-corrected systems.
• Team Collaboration: Work closely with experimentalists to integrate lab findings into architectural designs, and effectively communicate updates and insights across interdisciplinary teams.
• Documentation and Communication: Produce technical documents such as architecture white papers and QEC R&D roadmaps, and present research findings to technical and non-technical audiences.
This role is ideal for a motivated scientist who is eager to shape the future of quantum error correction in a dynamic, collaborative environment.

You'll need at least 3 years of experience in QEC research, gained in either an academic or industry setting. You should have deep expertise in QEC and a track record demonstrating your contributions to the field. Strong scientific computing skills and experience in developing and running simulations are essential, as is the ability to collaborate effectively with experimentalists, bridging theoretical insights with practical experimentation. Familiarity with atomic physics and experience with trapped-ion qubits or similar quantum platforms would be valuable. Additionally, having a background in collaborative software engineering projects, with the ability to contribute to code development and review, will be beneficial. Analytical skills for interpreting experimental data to refine QEC models and approaches are also highly desirable.
