Semiconductor quantum dots have emerged as promising nanostructures for efficient single-photon sources and have potential applications in quantum sensing, quantum communications, and quantum computing. In this talk, we review recent advances achieved in the field of quantum dot single-photon sources and explore their capabilities from multiple angles. The talk will begin with an introduction to high temperature operation of quantum dot single photon sources. Overcoming temperature constraints is critical for practical device implementations. The extension of single-photon emission to telecommunication wavelengths will also be discussed, an important milestone for seamless integration with existing optical communication infrastructure. In addition, the integration of quantum dot single-photon sources into silicon photonics circuits will be discussed. The integration of quantum dot technology and silicon photonics will pave the way for complex quantum photonic circuits.
