Description du poste

Alice & Bob is developing the first universal, fault‑tolerant quantum computer to solve the world’s hardest problems.

The quantum computer we envision building is based on a new kind of superconducting qubit: the Schrödinger cat qubit 🐈⬛. In comparison to other superconducting platforms, cat qubits have the astonishing ability to implement quantum error correction autonomously!

We're a diverse team of 140+ brilliant minds from over 20 countries united by a single goal: to revolutionise computing with a practical fault‑tolerant quantum machine. Are you ready to take on unprecedented challenges and contribute to revolutionising technology? Join us, and let's shape the future of quantum computing together!

Inside the Quantum Hardware department, the Nanofabrication Front End team is in charge of producing the superconducting circuits that serve as a basis of our quantum computer. The manufacturing process involves using thin film deposition and patterning methods (evaporation, etching, lithography…) performed in a cleanroom environment. The team is in charge of developing and improving the process, and manufactures the prototype chips of the company.

Are you passionate about cutting‑edge technology and eager to work on groundbreaking innovations in quantum computing? As a Nanofabrication Process Intern at Alice & Bob, you'll play a pivotal role in the fabrication of superconducting circuits—critical components for next‑generation quantum processors.

During this 6‑month internship, you’ll support the nanofabrication team in daily lab activities, including basic fabrication processes, device testing, and data analysis. You’ll collaborate with engineers and researchers, learning how state‑of‑the‑art quantum devices are designed, fabricated, and characterised, while gaining exposure to cleanroom protocols and advanced lab equipment.

A key focus of your internship will be on aluminium airbridges, essential structures in superconducting circuits. You will actively work on reviewing and optimizing fabrication processes, testing new approaches to improve quality, consistency, and scalability. You will also learn to characterize airbridge quality using techniques such as optical inspection and microscopy, gaining hands‑on experience in how fabrication choices affect device performance and collaborating directly in the cleanroom environment.

This is a unique opportunity to contribute to a revolutionary field, learn from experienced experts, and experience the technical life of a cutting‑edge nanofabrication facility. If you’re enthusiastic about technology, eager to learn, and excited about quantum innovation, we’d love to have you on our team!

Responsibilities:

• Review and analyze existing nanofabrication processes: Study the current methods used to fabricate aluminium airbridges for superconducting circuits. Identify potential issues or inefficiencies in the process.
• Develop and implement process improvements: Propose and test new techniques to enhance the fabrication process, focusing on quality, consistency, and scalability of the airbridge structures.
• Characterize and evaluate airbridge quality: Use advanced characterization techniques (including SEM, AFM, and optical inspection) to assess the quality of fabricated airbridges. Correlate measurements with contamination levels and other process parameters.
• Correlate contamination and defects: Investigate how different contamination sources (e.g., particulate, chemical residues, etc.) affect the performance of devices.
• Collaborate in the cleanroom: Work directly in the cleanroom environment to fabricate, test, and optimise airbridge structures. Collaborate with other engineers and scientists to align on goals and share progress.
• Documentation and reporting: Maintain detailed documentation of your findings, experimental setups, and results. Present your work regularly to the team and contribute to technical reports.

Requirements:

• Educational Background: Enrolled in a master’s degree in nanofabrication, physical characterization, semiconductors or equivalent.
• Technical Skills: Hands‑on optical lithography. Basic knowledge of dry and chemical etching, thin‑film deposition.
• Key Competencies: Meticulous and patient; strong communication skills and a collaborative mindset; proactive, curious, and committed attitude toward work and personal development.
• Bonus: Experience in fabricating superconducting circuits.

Benefits:

• 1 day off per month
• Half of transportation cost coverage (as per French law)
• Meal vouchers with Swile, as well as access to a fully equipped and regularly stocked kitchen

Research shows that women might feel hesitant to apply for this job if they don't match 100% of the job requirements listed. This list is a guide, and we'd love to receive your application even if you think you're only a partial match. We are looking to build teams that innovate, not just tick boxes on a job spec.

You will join one of the most innovative startups in France at an early stage, to be part of a passionate and friendly team on its mission to build the first universal quantum computer!

We love to share and learn from one another, so you will be certain to innovate, develop new ideas, and have the space to grow.
