Summer positions at the Quantum technology laboratory

Chalmers is offering four full-time 2,5 month summer positions in quantum technology research. Apply today to gain hands-on experience at the forefront of quantum computing, sensing, and superconducting technologies!

Information about the laboratory
The Quantum Technology Laboratory (QTLab) at the Department of Microtechnology and Nanoscience (MC2) conducts research in quantum computing, sensing, transduction, thermodynamics, and foundations. By controlling matter at the quantum level, we explore novel ways to process information beyond classical limits. QTLab offers an international, dynamic research environment and is part of the Wallenberg Center for Quantum Technology . The laboratory has access to an excellent cleanroom facility at the Nanofabrication Laboratory for fabricating state-of-the-art devices.

See details below and please indicate in your application which role you are applying for.

Lab software development for the Quantum Sensing and Foundations lab
In the Quantum Sensing and Foundations lab we use optical light to control and read nanomechanical resonator motion. Your task will be to focus on the development of Python-based data acquisition software in our lab, including writing measurement drivers, implementing multi-instrument measurement functions, and testing them in our experimental setup. We also aim to achieve real-time read-out, analysis, feedback and control of nanomechanical resonators. To this end, a field programmable gate array (FPGA) is the best option and, if time permits, this task could be part of the summer job.

Qualifications:
- Experience with Python and Git
Meritorious: 
- Object-oriented programming and intrument control
- Interest in quantum technologies

Superconducting Cavity Plating
This project explores how plating the cavity around a distributed Al/Si superconducting resonator with a superconducting metal affects the Q-factor of the resonator. Achieving high-Q is a key research topic of qubits, as researched in the Quantum Computing group . It has been shown that having a high-quality superconducting cavity can improve the resonator Q-value. Using FEM simulations and modeling, you will study plating techniques (e.g. electroplating, sputtering), superconductor properties (e.g. oxidation), and cavity geometry as well as review literature to assess prior findings. The aim of the project is to understand what factors impact the Q-factor.

As a next step (beyond the summer position), we plan to fabricate devices and measure their Q-factors in cryostat - this could potentially be a masters thesis project. 

Qualifications: 
- MSc student in electrical engineering, physics or Quantum technology
Meritorious: 
- Experience in microwave theory
- Experience in FEM simulations
- Experience in electrical measurements

Optimization of CZ gates in a 25 Qubit device
The Quantum Computing group is developing the Tergite software stack, enabling the execution of complex quantum algorithms on our 25-qubit processor. A key focus is automating calibration to ensure reliable single- and two-qubit gate operations, as manual calibration is impractical. While single-qubit calibration is supported by our software, a standardized two-qubit gate calibration is still in development.

Under Michele Faucci Giannelli’s supervision, the selected student will collaborate with experts in quantum measurements and software development, providing hands-on experience in quantum technology and software engineering.

The project will focus on two primary tasks:

Qualifications:
- Experience with Python

Title: Integrated Superconducting Bias Tee
At the 202Q-lab , we explore quantum information processing, microwave quantum optics, and quantum thermodynamics using superconducting circuits. This project aims to develop a superconducting bias tee for integration into nearly quantum-limited amplifier and DC low-pass filter modules. The goal is to simplify cryogenic wiring and enhance the noise performance of our quantum setups. 

You will collaborate with team members  on parameter identification, design and simulation of a superconducting bias tee, including PCB and chip design. Fabrication will be handled by team members, and you will test its performance in cryogenic quantum setups. 

Qualifications:
- MSc courses in microwave engineering
Meritorious:
- Experience in microwave measurements, modeling and PCB design
