Application of quantum-based devices: trends and challenges

Revolutionary nanofabrication techniques and trends have opened the way to fabricating quantum wells, quantum wires and quantum dots that may provide the basic building blocks for future nanoelectronic and mesoscopic (quantum) device technologies. Furthermore, these trends lead to new opportunities for realizing quantum-based information processing devices but many challenges must be addressed and intensive international basic research is essential for the full exploitation of these revolutionary devices.
