Invited CEA-Leti Paper at IEDM 2021 Identifies Main Challenges Facing Large-Scale Si Quantum Computing

SAN FRANCISCO - Dec. CEA, in collaboration with CNRS Néel, a leading team in SI-based quantum c'omputing, 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. The invited paper, "Material and integration challenges for large scale Si quantum computing" , was featured in a special Focus Session, "Device Technology for Quantum Computing", at the Dec. 11-15 meeting. Presented by Maud Vinet, director of CEA-Leti's quantum computing program, the paper notes that Si spin qubits are "very promising" for enabling large scale quantum computing because they are fast and small and of high quality. "They also derive directly from advanced CMOS technologies, which is good news for scalability," said Vinet, the lead author of the paper.
