Optical spin initialization and nondestructive measurement in a quantum dot molecule

Optical spin initialization and nondestructive measurement in a quantum dot molecule

The spin of an electron in an InAs/GaAs quantum-dot molecule is optically prepared and nondestructively measured through trion-triplet states. With two-laser transmission spectroscopy we demonstrate both simultaneously, something not previously accomplished in single quantum dots.
