QDotsWe study the dynamic control of the occupancy state and the quantized energy levels of quantum dot and quantum post nanostructures.

Goals include the realization of a precisely triggered single photon source and the implementation of acoustically controlled quantum logic operations.

Here's a short video animation on a SAW-pumped single photon source (SAW-SPS) using a self-assembled quantum post (QP)
