Internship on Fault-Tolerant Quantum Circuit Compilation
Quantinuum
Cambridge, UK
Posted on Jun 18, 2025
As part of our mission to expand our world class team at Quantinuum, we look for talented and high potential individuals to join us in an internship position. In this offer, we are looking for a candidate to contribute to our Fault-Tolerant Quantum Computing (FTQC) software stack. Depending on your background and strengths, you will be working on either:
- QEC-aware circuit optimisation. Quantum circuit optimisers in the FTQC era must guarantee fault-tolerance and minimise the overheads imposed by Quantum Error Correction. We are looking for researchers familiar with the mathematics behind QEC and with prior experience on quantum circuit optimisation, or combinatorial optimisation in general.
- Development of the QEC framework. The new software stack for the FTQC era introduces an additional abstraction layer between the user and the quantum computer: the encoding of the user’s circuit. We are looking for engineers with background in quantum computing and basic understanding of QEC to tackle the engineering challenges of Quantinuum’s new FTQC stack.
We are looking for:
- Background. MSc and PhD students on quantum computing, with computer science studies or hands-on experience.
- Requirements. Basic understanding of QEC, experience in combinatorial optimisation and programming.
- Research skills. Search and read scientific literature, critical thinking, ability to come up with ideas independently and communicate problems effectively.
- Engineering skills. Ability to design and implement solutions with a focus on maintainability and extensibility. Ability to integrate the solutions on the existing software stack.
What is in it for you?
Working alongside a highly talented team, with experienced researchers in the quantum computing industry. We offer a competitive salary for interns and a great working environment. These roles provide great development and learning opportunities to advance your career.
You will collaborate with researchers and engineers in Quantinuum’s TKET team and participate in discussions with the QEC team. A member of the TKET team will supervise your project and meet with you on a regular basis.
