Job summary

Pasqal in Palaiseau, France, seeks an AMO Physicist (W/M) at mid-level for its Hardware department. The role covers processing operations for neutral-atom QPUs, from state preparation to entangling operations, with emphasis on experimental validation and theory-experiment integration.

You will design benchmarking experiments, develop numerical models, identify dominant error sources, and contribute to circuit-level execution and QEC testing, collaborating with hardware and software teams.

Responsibilities

• Experimental characterization & optimization: Implement, characterize, and optimize processing operations (state preparation, gates, dynamical decoupling, coherent transport).
• Benchmarking experiments: Design and run benchmarking experiments to quantify performance, robustness, and limitations.
• Modeling & simulation: Develop and use numerical models to interpret experimental results, predict performance, and guide optimization.
• Error identification & mitigation: Identify dominant experimental error sources and drive mitigation actions with hardware and software stakeholders.
• Circuit-level execution: Support circuit-level execution, including gate scheduling, dynamical decoupling strategies, error accumulation analysis, and QEC protocols.
• Hardware feature validation: Contribute to validation of new hardware features by defining test plans and evaluating impact on processing performance.
• Documentation and communication: Write reports, technical documents, and scientific articles.

Job description

AMO Physicist - W/M at Pasqal, Palaiseau, Europe, FR. A mid-level full time position in the Engineering team, listed under hardware engineering.

Job Description

Within the Hardware department, the Processing team develops and validates the physical operations executed during the processing/computation phase of Pasqal’s neutral-atom QPUs (from state preparation to control and entangling operations). The team brings together a mix of experimental and theoretical/numerical profiles, ensuring continuous alignment between modeling work and experimental reality. We are looking for a profile at the theory-experiment interface who will be strongly involved in the characterization and optimization of processing operations, while also supporting circuit-level execution (e.g., dynamical decoupling, implementation of QEC protocols).

Responsibilities

• Experimental characterization & optimization: Implement, characterize, and optimize processing operations (state preparation, gates, dynamical decoupling, coherent transport).
• Benchmarking experiments: Design and run benchmarking experiments (e.g., randomized benchmarking and related protocols) to quantify performance, robustness, and limitations.
• Modeling & simulation: Develop and use numerical models to interpret experimental results, predict performance, and guide the optimization of processing operations
• Error identification & mitigation: Identify dominant experimental error sources (e.g., laser noise, motional effects, crosstalk, loss) and drive mitigation actions with relevant hardware and software stakeholders.
• Circuit-level execution: Support circuit-level execution, including gate scheduling, dynamical decoupling strategies, error accumulation analysis, and the implementation/benchmarking of QEC protocols
• Hardware feature validation: Contribute to the validation of new hardware features by defining test plans, running experimental evaluations, and quantifying their impact on processing performance.
• Documentation and communication: Write reports, technical documents, and scientific articles.

Benefits

• Beautiful modern offices in Massy
• A flexible rhythm of face-to-face work (minimum 3 days per week)
• Type of contract : CDI
• A dynamic and close-knit international team
• A key role in a growing start-up
• Free time to train and go to conferences/meetups
