QDot Optical Memory systems
*some excerpts:
"Moreover, the scientists state that the ability to address all three spin components –parallel and perpendicular to applied magnetic field – as well as the energy level structure of localized trions being identical in quantum wells and self-assembled quantum dots make their approach "highly appealing" for future memory device applications and may lead to the fabrication of semiconductor nanostructure-based optical memories."

"In order to increase the efficiency and to achieve longer delays for photon echoes it is necessary to try different type of semiconductor nanostructures which can be also based on other compounds.,' Akimov explained. "One of such candidates is the ensemble of quantum dots where the electrons and holes are localized much more strongly in all three dimensions. This is in contrast to quantum wells where strong confinement is present only along one direction"

"Along these exploratory lines, Phys.org asked Akimov if, given that storage times of seconds or longer might be possible by further exploiting the hyperfine interaction between electrons and nuclei in quantum dots, quantum wells and self-assembling quantum dots might at some point be combined in a single quantum system that emulates human short- and long-term memory."
