Ultrafast control of silicon-based semiconductor spin qubits

Xinhua News Agency, May 9, according to the University of Science and Technology of China, Professor Guo Guoping, Professor Li Haiou and others from the academician team of the university cooperated with their domestic counterparts and Local Quantum Computing Co., Ltd. to realize the electric field regulation of spin quantum bit manipulation rate in silicon-based germanium quantum dots. And the spin flip rate exceeds the 1.2GHz spin qubit ultrafast manipulation, which is the highest reported in the semiconductor quantum dot system in the world, and has important guiding significance for improving the quality of spin qubits. The research results were published online in the international journal Nano Communications.
