General information
Organisation
The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, development and innovation in four main areas :
• defence and security,
• nuclear energy (fission and fusion),
• technological research for industry,
• fundamental research in the physical sciences and life sciences.
Drawing on its widely acknowledged expertise, and thanks to its 16000 technicians, engineers, researchers and staff, the CEA actively participates in collaborative projects with a large number of academic and industrial partners.
The CEA is established in ten centers spread throughout France

In the growing field of quantum technologies, you will work on the simulation and design of superconducting parametric amplifiers operating at the quantum limit for superconducting qubit readout.
Contract duration (months)
6
Job description
As an intern at CEA, you will work in a world-renowned reasearch organization. You will access unique experimental platforms, and be supervised by renowned experts to lead your missions.
Internship description:
Superconducting quantum processors as the ones developed by IBM and Google operate at 20 mK but show limits in scaling up the number of qubits. This mainly stems from the difficulty to compacify the readout chains, which use semiconductor-based amplifiers whose electrical resistance limits performances. They also have to be operated at 4K to dissipate the heat they produce.
The internship consists in designing new quantum-limited superconducting parametric amplifiers to replace semiconductor-based ones. The devices will be fabricated in the industrial grade cleanroom of CEA-Leti and used to measure superconducting qubits.
Your missions will be:
- Parametric amplifier simulations
- Device design for fabrication in CEA-Leti cleanroom
- Following the device fabrication
- Superconducting qubit measurement in a dilution cryostat using the previously fabricated and characterized amplifiers.
Methods / Means
Python (simulations, experiment control, design, data processing)
