SUMMARY:András Pályi : Operating semiconductor spin qubits with geometric single-qubit gates at zero magnetic field
DESCRIPTION:\nAndrás Pályi, Budapest University of Technology and Economics\n\n\n\nLe résumé :\n\n\n\nSingle-electron spin qubits in semiconductor quantum dots provide a promising platform for quantum computing. Traditionally, such qubits are operated at a finite magnetic field, using resonant control with microwave pulses. A twofold major technological simplification of the platform would be achieved by operating the qubits (1) without a magnet, and (2) with baseband voltage pulses only.We propose such an architecture based on geometric single-qubit gates, which exploit spin-orbit interaction and the concept of the non-Abelian Berry phase. We also provide a roadmap of intermediate experimental milestones toward scaling up this architecture. The roadmap is based on recent progress with hole spin qubits in planar Germanium quantum wells.\n\n\n\nReference:http://arxiv.org/abs/2308.05455\n\n\n\nContact: andrej.meszaros@universite-paris-saclay.fr ( mailto:andrej.meszaros@universite-paris-saclay.fr )\n\n\n\n\n
