Senior Quantum Scientist

About the role

We are pioneering advancements in quantum computing by utilizing 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 minimizing 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.

Responsibilities

• You will:
• Prototype and characterize coherent control and cooling schemes for trapped-ion qubits using laser and microwave fields.
• Calibrate and benchmark quantum systems, focusing on achieving ultra-low gate errors and optimizing performance across device modules.
• Validate emerging trap technologies, including integrated electronics and photonics for large-scale architectures.
• Analyze experimental data, debug complex hardware/software interactions, and ensure reliability of qubit operations.
• Present results internally and externally, representing Oxford Ionics at conferences and in collaborations.

Requirements

• You will need:
• Proven expertise in experimental AMO physics or quantum computing. Experience with trapped ions is preferred.
• Strong collaborative skills, with the ability to work independently and as part of a fast-moving team
• Prior experience in one or more of the following: spectroscopy or simulation of multi-level systems, characterization of control hardware, gate fidelity benchmarking or running algorithms on hardware
• Strong proficiency in programming and data analysis.
• A track record of scientific communication through publications, talks and conferences.
• The approximate base salary range for this position is $ 126,887 - $166,127 . The total compensation package includes base, bonus, equity, and a range of benefit options found on our career site.
