Controlling Spin Qubits in Quantum Dots
We review progress on the spintronics proposal for quantum computing where the quantum bits (qubits) are implemented with electron spins. We calculate the exchange interaction of coupled quantum dots and present experiments, where the exchange coupling ...
Landau---Zener transitions in spin qubit encoded in three quantum dots
We study generation and dynamics of an exchange spin qubit encoded in three coherently coupled quantum dots with three electrons. For two geometries of the system, a linear and a triangular one, the creation and coherent control of the qubit states are ...
Current noise cross correlations and dynamical spin entanglement in coupled quantum dots
The authors investigate current noise cross correlations (CCs) through coupled double quantum dots under transport conditions. It is demonstrated that positive CCs relate to either thermal fluctuations at nonzero temperature or quantum tunneling ...
