Quobly , a deep tech company based in the Grenoble area, is developing a new generation of silicon-based quantum microprocessors. To support our ambition, we are looking for a Senior Quantum Measurement Researcher.
Your main mission will be to generate new ideas, open up new avenues and renew our understanding of quantum manipulation and measurement with a view to creating more powerful large-scale quantum processors.
Your tasks:
• Imagine, develop and implement original concepts to improve the reliability, robustness and efficiency of quantum manipulation and measurement.
• Propose new approaches to calibration, optimisation and testing for spin qubits.
• Understand the challenges surrounding spin qubits and be open to interacting at the level of quantum models and CMOS concepts applied to spin qubits
• Explore new directions for the manipulation and measurement of interesting spin qubits with a view to large-scale quantum processors
• Create academic partnerships with research teams to fuel your thinking and produce scientific publications
• Actively participate in internal scientific discussions by contributing ideas to the scientific and innovation roadmap
Your profile :
• PhD holder in quantum physics, condensed matter or related disciplines
• 5 years' experience in research on spin qubits, measurement, control and calibration
• In-depth knowledge of qubit manipulation (preferably spin qubits)
• You are able to move from abstraction to concrete simulations
Above all, you are a creative thinker, capable of challenging conventional approaches and coming up with new solutions.
Your curiosity and intellectual independence will make all the difference.
