Superconducting Qubit Readout Using Multi-Stage Quantum Amplifiers
Design advanced parametric cryogenic amplifiers in a cleanroom environment to enhance superconducting quantum processor readouts.
Best for:Best for master's graduates in quantum engineering with a strong background in superconductivity and cryogenic device fabrication.
Overview
This PhD position is hosted at the Quantum Devices Laboratory within CEA, Université Grenoble Alpes. The research focuses on designing innovative parametric cryogenic amplifiers using superconducting materials to replace traditional semiconductor-based components. The successful candidate will fabricate these devices in the industrial-grade cleanroom of CEA-Leti and deploy them to measure superconducting qubits. This work addresses the scalability bottlenecks in current quantum processors by enabling simultaneous multi-qubit measurements.
What you'll do
- Design novel cryogenic parametric amplifiers based on superconducting materials
- Fabricate quantum devices within the industrial-grade cleanroom facilities of CEA-Leti
- Integrate and test designed amplifiers with superconducting quantum processors
- Characterize device performance at ultra-low temperatures around 20 mK
- Analyze experimental data and collaborate with research teams to optimize multi-qubit readout chains
