Master projects

Spin and microwave photon speaking together

Master project, starting early 2022
During the master project, you will take part of this exciting experiment in order to make spin and microwave photon speaking together. You will participate to the fabrication of the chip, with nano-fabrication steps done in our cleanroom. You will also learn to cool down this chip in a dilution refrigerator to a base temperature of 10milliKelvin. Finally, you will perform the complex measurements of this hybrid physics at the interplay between spin qubit and microwave circuitry. For that, you will have to control the electrostatic gating of the silicon transistor in order to set the spin qubit working point while monitoring the microwave response of the photon cavity. Experimental results and new manipulation protocols will be widely discuss with theoreticians participating to this project. This master project may continue as a PhD thesis.

Microwave Photonic Crystals: Towards quantum limited amplifiers

Master project, starting early 2022
The internship project is the study of one of the key part of traveling wave amplifier, their photonic crystal. Indeed, for traveling amplifiers to work, two conditions must be fulfilled: energy and momentum conservation. To achieve momentum conservation, we fabricate micro-designed photonic crystals to carefully bend the band structure of the amplifier resulting in a momentum conservation in a finite frequency band. The design of such crystals is complex and of critical importance to obtain wide band amplifier. Find the complete offer here.

Magnetic bound states in 2D superconductors

Master project, starting early 2022
The presence of a nanoscale magnetic scatterer (a single atom, a molecule, a quantum dot etc.) on the surface of a superconductor can lead to the emergence of bound states with peculiar spatial and spectral properties within the superconducting gap. These states can be topologically trivial (the case of so-called Shiba states) or not (predicted Majorana zero modes). Find the complete offer here.
