About the role

Key responsibilities & impact
  • Apply Tensor Network methods to the classical simulation of quantum systems, circuits and architectures
  • Investigate scientific questions, review relevant approaches and select suitable numerical methodologies
  • Develop research-grade simulations adapted to Quandela’s hardware and future SPOQC architectures
  • Study entanglement growth, simulation of complexity and the propagation of physical noise
  • Explore different hardware configurations and architecture choices through numerical modelling
  • Simulate quantum algorithms and contribute to comparisons with relevant classical approaches
  • Develop reusable scientific code and document methods so they can support research across different teams
  • Contribute to scientific discussions, publications and future research directions around classical simulation
  • During the first 3 months, become familiar with Quandela’s architectures and research questions, investigate relevant methods and propose a first simulation approach
  • Within 6–12 months, develop and validate methods on concrete problems, build reusable tools and take increasing ownership of projects across Device Physics and Quantum Information
  • Longer term, become a key contributor to classical simulation at Quandela and extend the work toward future architectures, compilation or algorithm-level studies
