Direct transfer of two-electron quantum states in ac-driven triple quantum dots

Picó-Cortés, Jordi ; Gallego-Marcos, Fernando ; Platero, Gloria


We propose a protocol to prepare a state in the left and center quantum dots of a triple dot array and transfer it directly to the center and right dots. Initially the state is prepared combining the exchange interaction and magnetic field gradients. Once in the desired state, ac gate voltages in the outer dots are switched on, allowing to select a given photoassisted long-range path and to ...
