Internship: Quandela's fault-tolerant architecture team

Posted October 13, 2025
Full-time Internship

Job Overview

Quandela stands as a global leader in quantum computing, driven by groundbreaking technology and a strategic vision for scaling quantum solutions. The company’s unique ability to offer both hardware and software solutions, along with its commitment to build energy efficient datacenters and scalability, positions it to play a key role in the next wave of innovation, and in many strategic and sovereign industrial sectors. 

Join Us at the Forefront of Quantum Computing Innovation 🚀 

Description of the Project

Quantum information needs to be protected from errors. This is usually done by spreading the quantum information into a bigger system, called a quantum error-correcting code. The sources of errors and how they spread highly depend on the designed architecture. Quandela's fault-tolerant architecture is a hybrid spin-photon platform, called SPOQC, where information is encoded in the spin degree of freedom of semi-conductor quantum dots, which then interact through the photons they emit. The ability to create spin-photon entanglement makes the approach efficient and scalable. In this internship, you will join the team in its efforts to further improve the performances of the SPOQC architecture.



Topics of interest in the team include:

  • Increase the fault-tolerant thresholds of SPOQC
  • Reduce the footprint of the logical qubits 
  • Find the most efficient way to perform logical gates 
  • Estimate and optimise the resources needed to implement large-scale algorithms 

Your Key Responsibilities:

  • Review literature on quantum error-correcting codes, fault-tolerant protocols, simulations of Clifford circuits
  • Conduct research in quantum error correction and fault-tolerant quantum computing
  • Implement code to simulate and benchmark techniques for fault tolerance
  • Write an internal report on findings

Requirements

  • You are currently enrolled in a university or in a higher education program in Physics, Mathematics, Computer Science, Electrical and Computer Engineering or related fields
  • You are curious and love solving problems
  • You have experience with, or strong interest in quantum computing or quantum information theory
  • Coding skills are appreciated (Python, C#, C/C++, etc.)
  • Knowledge in quantum error correction and/or fault-tolerant techniques is a bonus

How to apply

In your application, please:

  • Provide a CV
  • Describe your motivation for joining Quandela
  • List any previous or relevant courses, experience or internships that relate to topics being developed at Quandela
  • Specify your period of availability (if relevant, you can mention any additional school requirements or timing constraints)
  • Specify whether you need a student visa for this internship

Benefits
