Objective
Since their discovery in 1991, single walled carbon nanotubes (SWNTs) have led to a worldwide explosion of research activities due to their outstanding electrical properties. Ten years later, the demonstration of optical emission from semiconducting SWNTs has opened a new field for nano-optics. In terms of quantum information processing, it has been recently shown that SWNTs are promising candidates for single spin quantum computing. Combined with their promising optical properties, this naturally promotes SWNTs as an ideal system to fulfil a crucial goal in quantum information processing, i.e. to link solid state qubits used for information processing (single spins) with flying qubits used for transmitting quantum information (photons). Schemes aiming at manipulating spins in semiconducting nanotubes all-optically, and more general applications of quantum optics necessitate the ability to confine electrons and holes (excitons) in a small recombination region called an optical quantum dot. One significant disadvantage of SWNTs with respect to optics is that, unlike in epitaxially grown semiconducting heterostructures, there is no obvious way to controllably confine excitons. In the proposed project, I will engineer and control an optically active quantum dot in an ultraclean suspended nanotube by means of an innovative approach aiming at exploiting the nanotube many-body interactions, and study its far-field optical properties. In a second step, I will study the coupling of the defined quantum dot to surface plasmons via metallic nanowire guides. This will constitute an important step towards future buses for transferring quantum information at the nanoscale through on chip flying qubits. These two experiments will be realised in a new type of devices recently developed in the Quantum Transport group at TU Delft, using a new technology combining a set of local electrical gates acting on single ultraclean suspended nanotubes.
