A postdoc position is open at Institut Néel in the team Nanophysics and Semiconductors (NPSC).
Within the framework of the ANR project Microwave rare-earth spin interfaces for quantum information processing – MIRESPIN, involving the Institut de Recherche de Chimie Paris and the Service de physique de l'état condensé (CEA-Saclay), we aim at controlling rare-earth ions at low concentration with two objectives: single spin RF control and RF to optical transduction, both involving high Q resonators.
At the Institut Néel, we focus on RF to optical transduction based on a good knowledge of the spin and optical transitions of erbium doped samples which are compatible with the fibered telecom range. Appropriate compound and experimental working conditions (spin and optical transitions of interest, magnetic field orientation, temperature …) still need to be investigated to provide an efficient opto-RF converter. The physical design of the resonator with a prime focus on the RF interaction enhancement will be implemented and tested first at moderate cryogenics temperature (1.5-2K) to validate the approach. This proof-of-principle will be a solid basis to adapt the setup for ultralow temperature operation (10-20mK).
The role of the candidate will be to do research on this project.


The postdoctoral researcher will be involved in the RF or optical characterizations of the samples, the resonator design and implementation, and nanofabrication to anticipate the integration of the next generation RF or photonic circuits.


• Doctorate degree in physics, less than 2-year experience.
• Experimental skills in at least one of the domains are required:
◦ RF or optical characterizations,
◦ resonator design and realization,
◦ nanofabrication
• Publications related to the field,
• Good level in English (written and oral)
• Spirit of initiative and independence

Work Context

The Institut Néel is a national research laboratory (CNRS) in Grenoble for fundamental research in condensed matter physics. The institute has about 300 staff members (160 researchers; 140 engineers and technicians) and is closely connected to the University Grenoble Alpes. The main research topics are: Quantum electronics, molecular and wide bandgap electronics; Magnetism and (molecular) spintronics; Photonics, plasmonics and non-linear optics; Correlated systems, quantum fluids and superconductivity; Materials: synthesis, structure and properties or functions; Instrumentation.
The candidate will join the team Nanophysics and Semiconductors (NPSC).
Active collaborations will be maintained within the framework of the ANR MIRESPIN project with the Institut de Recherche de Chimie Paris and the Service de physique de l'état condensé (CEA-Saclay).
