Two-year Postdoc position in Quantum Technologies: Electron Spin Resonance (possibility of a 12 month-extension) (Funded by Amidex)
RESEARCHER PROFILE: Postdoc / R2: PhD holders
RESEARCH FIELD(S)1: Physics
MAIN SUB RESEARCH FIELD OR DISCIPLINES1: Applied physics, condensed matter physics, quantum technology
JOB DESCRIPTION:
Position Overview
We are seeking a highly motivated postdoctoral researcher to join our cutting-edge project at the intersection of quantum technologies and advanced spin resonance techniques. This position focuses on developing innovative electron spin resonance (ESR) instrumentation for exploring clock transitions in rare-earth ions, a promising platform for quantum memories and microwave-optical photon interfacing.
Project Description
This project aims to address a key limitation of conventional ESR spectrometers, which operate at fixed frequencies (e.g., X-band, ~9.5 GHz), by developing a custom broadband ESR spectrometer. This instrument will enable fine-tuned exploration of the magnetic field (B₀) and microwave frequency (f₀) spectrum, essential for studying clock transitions in detail. Key objectives include:
Broadband ESR Development: Design and construction of an in-house ESR spectrometer capable of covering a wide frequency range.
Pulse ESR Capabilities: Integration of pulse functionalities to investigate quantum dynamics and coherence properties around clock transitions.
In-Situ Adjustable Resonators: Design, characterization and integration of resonators with dynamical frequency adjustability for in-situ tracking of clock transitions with high-sensitivity.
Laboratory and Research Environment
The successful candidate will join the Magnetism (MAG) Group at the IM2NP Laboratory which is a renowned research center in Marseille, with all facilities and expertise in materials science, nanotechnology, and condensed matter physics needed. Our environment allowed innovation and interdisciplinary collaboration, offering state-of-the-art tools for spectrometer development and advanced instrumentation.
As part of this project, the candidate will have access to IM2NP’s state-of-the-art platforms for electromagnetic simulations, cryogenic setups, and high-frequency instrumentation. Collaboration within the INFRANALYTICS national platform enhances access to high-performance analytical tools and fosters interactions with experts in spectroscopy and instrumentation across France. This integrated network offers a unique opportunity to work at the frontier of quantum technologies while benefiting from a robust infrastructure for innovation.
