We study coherent dynamics of two spatially separated electrons in a coupled semiconductor double quantum dot (DQD), in which various two-qubit operations are demonstrated just by adjusting the gate voltages. Especially, second-order correlated coherent oscillations provide functional quantum processes for making quantum correlation of separated particles. The results encourage searching quantum entanglement in electronic devices.Mesoscale and Nanoscale Physicstext
