About Pasqal

PASQAL designs and develops Quantum Processing Units (QPUs) and associated software tools.
Our innovative technology enables us to address use cases that are currently beyond the reach of the most powerful supercomputers; these cases can concern industrial application challenges as well as fundamental science needs.
In addition to the exceptional computing power they provide, QPUs are highly energy efficient and will contribute to a significant reduction in the carbon footprint of the HPC industry.

Job Description

As an intern in our Quantum Error Correction team, you'll work on developing and implementing simulation tools for atom loss errors in fault-tolerant quantum circuits and circuit-level optimizations specific to neutral atom platforms.

In this context, your main missions will be :

• Familiarize yourself with atom loss error models in neutral atom quantum
  computers and their impact on fault-tolerant quantum computation.
• Implement simulation frameworks for quantum error correction codes with
  atom loss, including repetition codes, surface codes and color codes.
• Analyze strategies for integrating loss detection into syndrome extraction
  with minimal overhead for deep circuits.
• Study delayed-erasure decoding techniques that leverage state-selective
  readout to correct loss errors when precise locations are unknown.
• Optimize quantum algorithms for Pasqal's neutral atom gate set and
  resource requirements.

You'll work on atom loss mitigation protocols that enable robust fault-tolerant computation, whichmay include:

• Circuit-level optimizations based on logical circuit structure (deep circuits vs.
  teleportation-based algorithms).
• Loss detection strategies tailored to different qubit loss fractions in the noise
  model.
• Teleportation-based loss mitigation for algorithms with frequent gate
  teleportation.
• Delayed-erasure decoder implementations compatible with general logical
  circuits and various QEC codes.
• Analysis of logical error rate as functions of loss fraction in experimentally
  motivated error models.

About you
