Job Description:

As part of the Theory team, you will implement numerical simulations for selected directional codes and benchmark several decoders on these codes under a relevant noise model. The internship will provide a comparative study: logical error rates vs. physical error rates (and runtime) and allow for the investigation of the possibility of increasing the encoding rates with increased connectivity.

Job Responsibility:

  • Understand the basics concepts of Quantum Error Correction (QEC), e.g. data qubits, measure qubits, parity checks, logical qubits, circuit level noise, decoding algorithms
  • Understand the construction of directional codes
  • Select a few candidates for benchmarking, with around 60 data qubits
  • Implement their parity check matrices in Python, generate their syndrome extraction circuit using Stim and insert errors to the circuit (using Callisto-inspired noise model)
  • Compare their logical error rates via Monte Carlo simulations, using a few decoders (eg.BP+OSD,Tesseract,Relay-BP)
  • Explore machine learning based code discovery to extend the construction of these codes

Requirements:

  • You speak English fluently
  • You have strong background in quantum physics and linear algebra
  • You have completed courses in quantum information or quantum computing
  • You have Python programming skills
  • You are curious to learn more about quantum error correction, and work in a start-up environment
