Quantum computers hold great promise for advancing science, technology, and society by solving problems beyond classical computersapos; capabilities. One of the most promising quantum bit (qubit) technologies are spin qubits, based on quantum dots (QDs) that leverage the great maturity and scalability of semiconductor technologies. However, scaling up the number of spin qubits requires overcoming...

Cryo-electron tomography (CET) is a powerful technique for the 3D structural analysis of biological samples in their near-native state. CET has seen remarkable advances in instrumentation in the last decade but the classical weighted back-projection (WBP) remains by far the standard CET reconstruction method. Due to radiation damage and the limited tilt range within the...

For many years, CEA has been involved in the development of semiconductor-based X-ray and gamma-ray spectrometric imagers (20keV-1MeV). The main applications targeted are medical imaging, nuclear, security and astronomical observations. State of the art detectors based on Cadmium Telluride single crystals (Cd(Zn)Te) are efficient but costly and their detection area is limited. In recent years,...
