Quantum technologies like modern cryptography, quantum computing and quantum memories will surely have a great impact on our everyday life in the near future. The promise of unprecedented computing speed offered by quantum computers imposes at the same a need to improve the encryption methods. Numerous research groups are involved in using quantum mechanics to work out new concepts and architectures to implement quantum communication in devices.
The goal of this project is to develop one of the key components needed for quantum technologies: single photon light sources (e.g. for quantum key distribution protocol in telecommunication networks). An ideal single-photon source (SPS) for these applications should strictly provide on-demand generation of only one photon at ultrashort temporal intervals, with predefined and deterministic optical linear polarization, at temperatures relevant to on-chip environments. For the purpose of quantum computation these single photons should also be indistinguishable in their optical properties.
