Job description

Overview

We are seeking a postdoc to co-design efficient and realistic simulation algorithms for noisy quantum circuits in superconducting hardware, combining quantum modeling with hardware-aware performance engineering. The work involves simulations for quantum error correction and mid-circuit operations, and will require both low-level optimization skills (e.g., SIMD, GPU, FPGA) and an understanding of quantum simulation trade-offs. The role supports integration with a 25-qubit chip and involves close collaboration with physicists and engineers to push the boundaries of scalable, high-fidelity quantum simulations.

About the project

This project is part of QuantumStack, a 5-year project funded by the Swedish Foundation for Strategic Research, with the aim of developing a full software stack for programming quantum computers. The project is integrated with the Wallenberg Centre for Quantum Technology (WACQT), a 12-year, billion-SEK initiative started in 2018 with the purpose of advancing Swedish academia and industry to the forefront of quantum technology, and to build a Swedish quantum computer. Our ambitious goal at Chalmers is to build this quantum computer with 100 superconducting qubits and to apply it to real computational problems that cannot be efficiently solved on a conventional computer. Such computationally hard problems are found, e.g., in optimization, quantum chemistry, materials science, machine learning, etc.

Responsibilities

• Co-design efficient and realistic simulation algorithms for noisy quantum circuits in superconducting hardware.
• Combine quantum modeling with hardware-aware performance engineering to achieve scalable, high-fidelity simulations.
• Perform simulations for quantum error correction and mid-circuit operations.
• Develop and apply low-level optimization skills (e.g., SIMD, GPU, FPGA) and evaluate quantum simulation trade-offs.
• Collaborate closely with physicists and engineers to integrate simulations with a 25-qubit chip.

Qualifications

• Background in performance engineering and high-performance computing hardware (high-performance CPUs and GPUs) and modeling of quantum computer systems.
• PhD in computer science and/or engineering (computer architecture and HPC related topics) with knowledge in quantum computing, or PhD in physics (quantum computing related topic) with knowledge in HPC systems and performance engineering.
