Open positions

Our laboratory is always open to potential new candidates: if interested, contact Prof. Pasquale Scarlino (and the project contact when applicable) with a motivation letter, a full CV and academic track records to inquire about available research positions in the laboratory.

Postdoc positions available in HQC lab (EPFL Switzerland)

We are looking for a highly motivated post-doctoral researcher to work on the design, fabrication, and characterization of superconducting-semiconducting hybrid devices and superconducting metamaterials. The work will be part of the SNF project ‘High Impedance Metamaterials for Quantum Simulation with Semiconductor/Superconductor Hybrid Circuits.’ This position is immediately available, and we will be continuously evaluating applications. All applications filled in by July 15, 2021 will receive full consideration.

Master’s Thesis Projects:

TQD in Ge/SiGe coupled to a high-impedance SQUID array resonator. A DQD is formed in a Ge/SiGe quantum well (pink) by confining holes with electrostatic gates (orange and yellow). The λ/4-resonator (violet) is coupled to the readout line in a hanged configuration and it is galvanically connected to one of the DQD gates (violet). The vacuum-Rabi splitting of the cavity mode is a signature of strong charge-photon coupling.

The project is going to aim to model, design and perform measurements on the platform. The project will consist of three main phases:

  1. Modelling and Simulation. In the first months, the student will learn about multimode quantum electrodynamics and atom photon bound states. The student will then simulate the platform.
  2. Design and Fabrication. The student will learn how to design and fabricate the device.  
  3. Measurements. The device will then be measured in a LD250 dilution refrigerator, a cryogenic system capable of reaching temperatures in the range of 10 mK.
