Job description

Quoted in full from C12 Quantum Electronics's job posting. Gavroche does not edit it.

Founded in 2020 and based in the heart of Paris, C12’s mission is to be at the center of one of the biggest technological breakthroughs of the century and change the course of history by building a universal quantum computer.
At C12, we believe that achieving a true breakthrough in quantum computing requires rethinking the fundamentals. That’s why our founders—deeply rooted in academic and engineering excellence—have chosen carbon nanotubes as the building blocks of our quantum processors. This ultra-pure material dramatically reduces error rates, boosts performance, and minimizes hardware overhead—key ingredients for scalable, fault-tolerant quantum computing. By crafting a unique approach that scales, we aim to revolutionize quantum computing just as silicon transformed classical computing.
 
Since our founding, we’ve raised over €25 million in funding, published 11 scientific papers, and secured 8 patents. Today, our fast-growing team of 80+, including 25 PhDs, has over 26 nationalities represented. We have our own cutting-edge lab spaces in Paris' historic Panthéon district, where scientists, engineers, and innovators work side-by-side to tackle some of the most exciting technical challenges of our time.
 
If you're passionate about shaping the future of quantum technology and want to make a real impact, C12 offers a unique environment to grow, learn, and innovate.

Your role at C12:

    An optimal qubit calibration is a necessary condition for a good and operational quantum computer. Calibrating qubits is a highly non-trivial task which requires playing with lots of parameters at the same time and due to design variability, must be performed from scratch for every new chip. Thankfully, recent advancements in AI and Machine Learning overcome these difficulties and help accelerate qubit calibration and quantum hardware research.

    As part of the AI for Quantum team at C12, you will design, develop and deploy qubit calibration algorithms. Your goal will be to use AI and ML tools to automate certain phases of qubit calibration and, by doing so, support our Qubit Control team.

    Your job will involve:

  • Scientific reading (articles, open-source solutions, …)

  • Implementation of cutting-edge algorithms for qubit calibration

  • Writing and maintaining the code base for industrialisation purposes

  • Testing and measuring on C12’s quantum chips

About You:

  • You are enrolled in a Master’s program in Physics, Computer Science, Machine Learning, Mathematics, or a related field

  • You have an appetite for coding

  • You are eager to learn physics and to interact with both scientists and developers on a daily basis

    • Requirements

  • You are proficient in Python

  • You have good experience with AI and Machine Learning tools

  • You have some knowledge of Quantum Computing or Quantum Physics

  • You have a good level of English, both oral and written

What we offer our interns:

  • €1,400
  • Two incredible office spaces in the heart of Paris (both next to the famous Panthéon!)
  • Swile meal vouchers
  • Vibrant office culture (team lunches, offsite events, Friday breakfasts..)
  • Mental health support with moka.care
 
You should join us if...
 
  • You want to contribute to achieving landmark results in quantum computing, making a difference in the emerging quantum technologies
  • You want to work within a 80+ people team with various backgrounds in nanofabrication, quantum electronics, and carbon nanotube science to create a revolutionary quantum computing processor
  • You want to thrive in an exceptional scientific environment with several industrial and academic partners
  • You share our values (excellence, scientific integrity, diversity, curiosity, and care) and want to help us define our product-focused culture and ambition to accelerate
 
C12 encourages all who feel qualified to apply. Recruitment decisions are based solely on qualifications, skills, knowledge and experience.
Applications from women are particularly encouraged and welcomed!
