报告摘要：

Quantum computing attracts much interest as Moore’s Law seems to reach a limit in semiconductor industry. We report our progress in developing semiconductor qubits based on individual electron charges, spins, or hybrid states of charges and spins. Charge qubits can be coherently manipulated with picosecond voltage pulses. We developed single, double, and triple charge qubits in GaAs/AlGaAs heterostructures in the last few years. Spin qubits in Si devices possess much longer coherence time. We report our efforts in making spin qubits in stack-gated Si MOS-FET devices. Recently, we made progress in realizing a type of hybrid qubits, which compromise the fast operational speed of charge qubits and the long coherence time of spin qubits.

报告人简介：

Dr. Xiao Ming now is a professor in the Key Laboratory of Quantum Information, University of Science and Technology of China. Dr. Xiao received his Ph. D. degree in experimental condensed matter physics from University of California at Los Angeles (UCLA) in 2004. His research focuses on the manipulation of a single electron spin or charge in nanometer-scale semiconductor devices to implement quantum computing. In silicon MOS FETs and quantum dots, he realized the detection and manipulation of a single electron spin. In GaAs/AlGaAs quantum dots, he performed quantum operations of a single charge qubit, two and three strongly coupled charge qubits, and a tunable spin-charge hybrid qubit.
