Streszczenie:
Quantum dots have been shown to be bright sources of single photons. However, for quantum network schemes entanglement is required and single photons are not sufficient. Entanglement of photons and local quantum memories to build memory based quantum repeaters is a possible path towards building a quantum network. An alternative approach, the so called memory-less quantum repeater needs complex entangled photonic states, so called cluster states, as a resource. In this talk, I will introduce the concept of communication with quantum security and show why and how this can be expanded to quantum networks. I will introduce the concepts of memory-based and memory-less quantum repeaters and I will show the advances and challenges of using quantum dots in a memory based quantum repeater network.
