Introduction
A quantum computer uses qubits rather than bits to store and process information.
More information: Quantum computer
Possible applications are quantum dots (QDs) as single-photon sources for quantum information processing or coupled QDs as solid state qubits for information storage (quantum computing)

QD molecule
A quantum dot molecule is one possible approach to form a qubit.
An applied electric field can be used to switch between the states, e.g. direct vs. indirect exciton. -
Coupled quantum wires
One-dimensional electron transport in combination with wavefunction engineering has been proposed for the use in solid state quantum information processing. An example of such a system is studied in this tutorial:
