Postdoctoral position on the modeling of silicon spin qubits

A post-doctoral position is opened at the Interdisciplinary Research Institute of Grenoble (IRIG) of the CEA Grenoble (France) on the theory and modeling of silicon spin quantum bits (qubits). The selected candidate is expected to start at the beginning of year 2022, for up to two years.

Quantum information technologies on silicon have raised an increasing interest over the last few years. Grenoble is pushing forward an original platform based on the “silicon-on-insulator” (SOI) technology. In order to meet the challenges of quantum information technologies, is essential to support the experimental activity with state-of-the-art modeling. For that purpose, CEA is actively developing the “TB_Sim” code. TB_Sim is able to describe very realistic qubit structures down to the atomic scale when needed using atomistic tight-binding and multi-bands k.p models for the electronic structure of the materials. The aims of this postdoctoral position are to strengthen our understanding of spin qubits, and to progress in the design of efficient and reliable Si and Si/Ge spin qubit devices and arrays using a combination of analytical models and advanced numerical simulations with TB_Sim. Topics of interest include spin manipulation & readout in electron and hole qubits, exchange interactions in 1D and 2D arrays of qubits and operation of multi-qubit gates, sensitivity to noise (decoherence) and disorder (variability). This work takes place in the context of the EU QLSI project and will be strongly coupled to the experimental activity in Grenoble and among the partners of CEA in Europe.
