Nanotechnology Now - Press Release: Invited CEA-Leti Paper at IEDM 2021 Identifies Main Challenges Facing Large-Scale Si Quantum Computing: Second Paper Details Innovative Silicon Quantum Device Integration For Effective Qubit Control

CEA, in collaboration with CNRS Néel, a leading team in SI-based quantum computing, presented two papers on that topic at IEDM 2021, including an invited paper that identifies the material and integration challenges facing large-scale Si quantum computing. The second paper presents a novel Si quantum device integration that reduces by half the effective gate pitch and provides full controllability in 1D FD-SOI quantum dot (QD) arrays.
