Our ambition is to build large-scale fault-tolerant quantum computers. Before reaching full fault tolerance, intermediate architectures will continue to operate under significant hardware and noise constraints, making error mitigation an important part of understanding and improving their performance.

**

About this position:**

You will join Quandela’s Quantum Information team within Architecture, working at the interface between quantum information theory, architecture performance and fault-tolerant quantum computing. 

The team develops methods to benchmark, characterise and evaluate the computational performance of Quandela’s current and future architectures, helping guide hardware and architecture decisions. 

We are now looking to build dedicated expertise in Quantum Error Mitigation (QEM). 

You will develop and assess mitigation methods adapted to our photonic and spin-photonic systems, working closely with Quantum Information, Device Physics and FTQC researchers. 

Your goal will be to understand how QEM can improve computation fidelity and extend the useful depth of quantum circuits, while assessing its cost, limitations and interaction with error correction on realistic architectures. 

Requirements

What you'll do:

As a Quantum Information Scientist working on Quantum Error Mitigation, you will: 

• Develop and adapt QEM methods for photonic and spin-photonic architectures. 
• Evaluate their performance, feasibility and implementation cost. 
• Study how mitigation and Quantum Error Correction can complement each other across different operating regimes. 
• Use realistic noise models and hardware constraints to assess their impact on computational fidelity and achievable circuit depth. 
• Build scientific prototypes and numerical tools to test and compare different approaches.
