In quantum nanoelectronics, one of the major goals is the use of quantum mechanics for the development of nanoprocessors that are more and more efficient. This requires the ability to control quantum phenomena at the single electron scale within nanostructures. In this context, the degree of freedom of the electron spin has been identified as a potential candidate for the support of quantum information. We can define the elementary block of the nanoprocessor by capturing a single electron (and therefore its spin) inside a quantum dot. The development of a quantum circuit will follow the same methods of microelectronic circuits conception, by connecting the elementary bricks, while respecting the constraints of controlling the individual spins. Nowadays, in quantum dots systems, all the elementary operations required for the functioning of a quantum processor have been demonstrated in trapped spins of AsGa heterostructures. The effort of the spin qubits community turns to the transposition of these demonstrations for trapped spins in silicon structures, whose fabrication is compatible with CMOS industrial processes.
The candidate will develop research on the readout and coherent control of single electron quantum dot to form spin qubit. In particular, the candidate will investigate the interfacing of spin qubits with magnetic materials. She/he will be in charge of measurement of hybrid devices comprising a CMOS spin qubit and a spintronic unit (MRAM) that will be operated to achieve fast and high-fidelity readout. She/he will also develop new methods for the coherent driving of spin qubits through EDSR based on integrated nanomagnets and ferromagnetic resonance.


Most of the work will consist in doing experiments at cryogenic temperatures (<1K) to evaluate and benchmark the different strategies for reading and controlling spin qubits. The candidate will have the opportunity to work with devices made at the CEA LETI's foundry in an industrial CMOS process line. The candidate will also work in close collaboration with SPINTEC researchers, where she/he will benefit from their expertise as one of the leading spintronics research laboratories worldwide. Supervising a PhD student will be also part of the position.


It is mandatory to have presented a PhD thesis defense in the following topics: condensed matter, micro–nanotechnologies or quantum physics.
- Good Knowledge of semiconductor devices
- Knowledge of the physics of quantum dot and spin qubits and/or in spintronic devices
- Knowledge in the operation of cryogenic apparatus and expertise in microwave and radiofrequency techniques desirables
- Good written and spoken English skills required
- Good communication
- Ability to write reports/articles
- Ability to work in a team

Contexte de travail

This work is part of a large collaborative effort between the CEA-IRIG, CEA-LETI and CNRS-Institut Néel to develop and push the technology of spin qubit in silicon and investigate its potential scalability. Moreover, the applicant will benefit from the collaboration with Spintec on the integration and operation of magnetic components in the CMOS device.
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.
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.
