QEC Researcher (Quantum Simulations)

Cambridge, UK | Full-time | Permanent | Hybrid

Salary: £70,000 - £85,000

The salary range for this role is broad, as we are able to consider varying levels of experience.  Any offer made will carefully take into account level of experience (including relevant industry experience), transferable relevant skills and previous relevant achievements. 

We will also consider part-time applications for this role. Please indicate your preferred working schedule in your cover letter.  

As a QEC Researcher (Quantum Simulation) at Riverlane, you will work on the development and application of classical simulation techniques for fault-tolerant quantum computing and quantum error correction. 

The team brings together mathematicians, physicists, and chemists, and works closely with leading researchers in quantum algorithms and QEC. A core part of the role is contributing to the academic community through publications and conference participation.  

This role focuses is enhancing and extending existing simulation tools to support the analysis, validation, and optimisation of quantum error-correction systems. This includes developing simulation capabilities for circuits dominated by Clifford operations, investigating the accuracy, complexity, and limitations of simulation approximations, and enabling large-scale studies of quantum error channels for non-Clifford QEC circuits and decoder performance. 

Your work may include optimising quantum circuit compilation for specific QEC primitives, analyzing circuits for their effective error channels, and working to improve existing magic state preparation techniques in a hardware informed way. 

You’ll collaborate closely with other QEC teams at Riverlane, including those working on logical operations, decoding and QEC code design across different qubit platforms. 

• →Develop and improve simulation tools for fault-tolerant quantum computing and quantum error correction.
