Quantum Engineer

As a vital member of the Quantum Measurement Team at Quobly, you will work on enabling high-fidelity quantum operations on our Quantum Processing Units (QPU) based on semiconductor spin qubits made using industrial FD-SOI technology.

You will work collaboratively with other teams to:

• Build and perform calibration sequences to bring the quantum device to its operating point.
• Design and implement optimal control sequences to enable quantum operations.
• Characterize and benchmark the quantum processes to enable high fidelity operations on the QPU.

We place a high emphasis on fostering creativity, encouraging diverse perspectives, promoting collaborative efforts, and embracing both agile problem-solving and dependable, consistent performance. Being an early-stage team, you will have the unique opportunity to shape our roadmap and contribute significantly to our endeavors.

• PhD in Physics, Engineering, or related fields, or equivalent industry experience.
• Good understanding of semiconductor spin qubits.
• Experience in developing software (python) to interface with hardware and for data analysis.
• Good verbal and written communication skills.

Nice to have

• Experience in coherent control, characterization, and benchmarking of spins in solid state systems or other qubit systems.
• Experience with collaborative software development (version control, code review, etc.) and knowledge of good practices.
• Familiarity with the use of RF electronics (AWG, MW signal generators, IQ mixers) and measurement techniques.
• Understanding of CMOS devices, particularly the physics at low temperatures.
• Experience with cryogenic systems, in particular dilution refrigerators.

If you feel you may lack some of the skills listed, we encourage you to apply nonetheless. We firmly believe that your experience, coupled with a willingness to learn and a sense of adventure, can truly make a difference.
