Please apply for any of the following four positions that interest you.

QEC Theorist - Quantum Architect

Mission

Yaqumo is seeking a researcher with a background in quantum error correction, able to shape the fault-tolerance strategy for our devices and develop scalable neutral atom quantum computers. The potential of quantum computers relies upon large-scale fault-tolerant devices and this role will focus on designing quantum architectures for physical hardware.

This role involves developing and implementing designs for codes, qubit layouts, logical operation strategies, and optimal usage of the connectivity advantages of neutral atom devices. We are looking for candidates to actively engage in quantum error correction research and contribute to the wider research community through publication, while also engaging with real devices in collaboration with our Control Systems, Engineering and Software teams to realise the potential of fault-tolerant neutral atom quantum computers.

Responsibilities

• Analyse and design fault-tolerant circuits for syndrome measurement and logical operations.
• Optimise protocols for fault-tolerance, taking into consideration hardware constraints like atomic movement.
• Collaborate with other teams to incorporate necessary constraints into protocol design, as well as communicate the software and hardware requirements for fault-tolerant computation.
• Implement quantum error correction on neutral atom hardware.

QCVV Theorist - Quantum Metrologist

Mission

Yaqumo is seeking a researcher with a background in quantum characterisation, verification and validation, able to design and carry out experiments for assessing the performance of neutral atom quantum computers. The presence of unwanted noise on quantum hardware is a key hurdle for practical computation and this role will focus on extracting accurate information about device noise from experimental data.

This role involves designing experiments to evaluate performance metrics, identify correlations and unaccounted noise sources, and provide insights into pathways for improving neutral atom quantum devices. This includes working together with experimentalists to run experiments and to turn measurement data into actionable feedback aimed at improving device fidelities by eliminating or mitigating noise. Furthermore, it includes working with theorists to develop accurate simulations and predictive models for the performance of quantum hardware.

Responsibilities

• Design and carry out experiments that identify and isolate physical error mechanisms impacting performance, including systems with leakage.
• Quantify device performance with experiments at the physical and logical levels.
• Collaborate with experimental physicists and control engineers to improve device performance.
• Collaborate with quantum information theorists to translate device characterisation data into models with strong predictive capabilities for device performance.
• Develop data analysis tools to process experimental data for benchmarking.

QEC Theorist - Simulation and Decoding

Mission

Yaqumo is seeking a researcher with a background in quantum error correction, able to perform numerical simulations for analysing and evaluating the performance of schemes for fault-tolerance on neutral atom quantum computers. The potential of quantum computers relies upon large-scale fault-tolerant devices and this role will focus on evaluating fault-tolerant methods and their applicability to hardware, including the development and implementation of practical decoders.

This role involves determining which quantum error correction codes, decoders and fault-tolerant strategies are best suited for neutral atom hardware by quantifying logical performance under experimental constraints. This includes collaboration with Engineering teams to develop high-performance decoders and implement them in hardware. We are looking for candidates to actively engage in quantum error correction research and contribute to the wider research community through publication, while also engaging with real devices in collaboration with our Control Systems, Engineering and Software teams to realise the potential of fault-tolerant neutral atom quantum computers.

Responsibilities

• Perform numerical simulations to assess and compare the performance of state-of-the-art designs for quantum architectures.
• Develop practical decoders and work together with other teams to implement them in hardware, including real-time or low-latency decoding.
• Develop and maintain software tools for the performance analysis of fault-tolerant protocols.
• Implement quantum error correction on neutral atom hardware.

Quantum Algorithms Theorist - Resource Estimation and Design

Mission

Yaqumo is seeking a researcher with a background in quantum algorithms, able to assess, develop and adapt various algorithms for neutral atom quantum computers. There are many exciting applications of fault-tolerant quantum computers and this role will focus on assessing the viability of various algorithms for upcoming neutral atom devices and realising them on hardware.

This role involves incorporating hardware-aware constraints into the estimation of computational resources necessary for running quantum algorithms on neutral atom devices. This includes algorithm selection, circuit design, and logical resource estimation for application across many high-impact domains. We are looking for candidates to bridge application-level algorithm development to the constraints of hardware, to specify the scale of machine necessary to execute them, and to realise practical quantum advantage.

Responsibilities

• Identify, design, and evaluate viable quantum algorithms for neutral atom quantum computers.
• Compare algorithm implementations and identify trade-offs between accuracy, space costs, runtime, and demands of physical hardware.
• Incorporate hardware-aware constraints to implement algorithms that take advantage of neutral atom capabilities such as long-range connectivity and parallel operations.
• Evaluate and refine the logical resource costs of distinct fault-tolerance frameworks together with QEC theorists to estimate the full physical cost of algorithms under realistic assumptions.
• Communicate algorithmic costs and trade-offs, including the scale and requirements of future devices, to both internal technical staff and external audiences.
