Missions

As part of the Quantum Silicon Grenoble project, teams at Néel Institute, CEA-LETI and CEA-IRIG aim at building a quantum accelerator with silicon spin quantum bits (qubits). Compatible with large-scale production, existing integration processes on Si are a real advantage for the scalability of these qubits (see Fig.1). However, the reproducibility of charge and spin characteristics of these devices are yet to be explored and improved. This requires extensive/statistical electrical characterization and continuous feedback to process integration team.
Urgent needs on information of variability and reproducibility of spin qubits characteristics rise as fast as the need of integrating a large number of qubits on chip. With the popularization of new low temperature characterization tools (such as cryogenic probe stations and multiplexed matrices) to extract statistical information on the qubit and understand more deeply their properties, the development of measurement procedures, automation and efficient analysis methodologies appear as important tasks. The candidate will work on such tasks, in particular, to help our team to improve our actual knowledge on the reproducibility of charge and spin characteristics of FDSOI CMOS-based qubits. He will study different devices architectures and evaluate their performance, providing understanding on the associated physical effects. For this, the candidate will have the opportunity to use the low noise and ultra-low temperature electrical measurement techniques available in the spin qubit team.

Contexte de travail

The Institut NEEL, UPR 2940 CNRS, is one of the largest French national research institutes for fundamental research in condensed matter physics enriched by interdisciplinary activities at the interfaces with chemistry, engineering and biology. It is located in the heart of a unique scientific, industrial and cultural environment. It is part of one of Europe's biggest high-tech environment in micro- and nanoelectronics, right next to the French Alpes.
In the Institut Néel, the QuantECA team is specialized in the experimental study of quantum electronic devices, from fundamental studies to applications of quantum technologies. This work is part of a large collaborative effort to develop and push the technology of spin qubit in silicon and investigate its potential scalability. The candidate will work in a consortium made of Néel Institute, CEA-LETI and CEA-IRIG researchers, at the interface among characterization, simulation and process integration teams.
The Institut NEEL is a CNRS laboratory. CNRS is a public, scientific and technological organisation. The core mandate is to identify, carry out ou have carried out, either alone or with partners, all research that advances science or contributes to the country's economic, social, and cultural progress. Internationally recognised for the excellence of its scientific research, the CNRS is a reference in the world of research and development, as well as for the general public.
