The scheme for linear optics quantum computing as proposed by Knill, Laflamme and Milburn requires sources of single and indistinguishable photons, which will non-classically interfere at beamsplitter structures, phase-shifters and single-photon detectors. Photonic integrated circuits (PICs) offer a scalable way to realize the scheme. Semiconductor quantum dots can serve as efficient on-demand sources of single photons in PICs, however when grown in Stranski-Krastanov mode they usually emit over a broad distribution of different wavelengths due to the statistical size-distribution of the dots.
Here, we present possibilities of tuning the emission wavelengths of metal-organic vapor-phase epitaxy (MOVPE) grown semiconductor quantum dots and show how these mechanisms can be implemented in PICs to enable two-photon interference in such a circuit.
