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

At Pasqal, we design, build, operate, and sell quantum processing units (QPU) based
on neutral atoms [Pas, HJ20]. Fault-tolerant quantum computing (FTQC) is a quantum
computing design space in which the existence of processing errors is acknowledged,
and processors and computations are engineered to be robust against them [Got24].
Compelling academic demonstrations of fault-tolerant calculations with neutral atoms
[BL25] and resource estimation studies [ZL25], combined with drastic improvements
and breakthroughs on the quantum algorithms side [Gid25], put large scale useful neutral atoms quantum processors at reach of engineering. 

Pasqal is currently designing its future processors for the decade to come, with a clear intermediate “megaquops” milestone in 2029: QPUs performing 1 million quantum operations by the continuous operation of 10 000 atoms on a single machine.

Uniquely positioned at the interface between hardware, quantum error correction
(QEC), and quantum algorithms, you will help in the design of large-scale long-term
fault-tolerant quantum processing units. Your goal will be to compute and optimize the
concrete spacetime costs (qubit count and circuit depth) of fault-tolerant implementation of impactful quantum algorithms on future Pasqal machines. The exact mission
statement will be determined with the successful candidate prior signing the convention,
with a clear and well-scoped internship objective.

As part of our progress on Fault Tolerant Quantum Computing, we are recruiting an intern to reinforce our early FTQC team. 

In this context, your main missions will be :

• To familiarise with:
  • Quantum error correction and full or partial fault-tolerance.
  • State of the art quantum algorithms, algorithmic subroutines, and their logical costs.
  • Neutral atom technology, its peculiarities, pros, and cons in the context of fault tolerant implementation and the physical spacetime costs it entails.

• Resource estimation of physical costs for large quantum algorithms tailored to neutral atoms, using bleeding-edge algorithmic improvements, and adapting techniques from other qubits technology.
• Studying how physical costs of a given logical circuit evolve with the choice of QEC code, logical gates strategies, magic states creation strategies, etc.
• Studying how physical costs of a given logical circuit evolve with the physical parameters of the hardware: gate fidelities, gate duration, size of zones and other constraints, etc.
• Development and usage of tools to visualize and manipulate large, encoded quantum programs.
• Compilation of logical circuits into physical sequences of atomic operations and optimize it.
• Contribute to the original design of Pasqal megaquops QPU, handling 10 000 atoms.

About you

• Your are looking for your end of study internship.
• Knowledge in quantum information and quantum informatics.
• QEC experience from a previous internship or during studies, projects in school and such is appreciated.
• Programming experience with object oriented programming language, on high-level and low level programming (Python).
• Autonomous, proactive, thorough, reporting skills.
• Solid communication skills in French and English will be expected on this role to work on this project.

What we offer

• Offices in Paris and in Palaiseau
• Type of contract : Internship
• A dynamic and close-knit international team
• A key role in a growing scale-up

Recruitment process

• A soft skills interview with our Talent Acquisition Specialist of 30 min.
• A technical interview with your tutor for 60 min : 10 min use case presentation + 50 min discussion.
• A final interview with another teammate 30 min.
• An offer!
