    "abstract": "In the lectures we will be concerned with some aspects of physical\nimplementations of quantum gate operations which are necessary for quantum\ninformation processing. We will discuss two possible realizations. One of them\nis based on qubits being encoded in atomic degrees of freedom where the atoms\nare manipulated in optical lattices above atom chips. The other realization is\nbased on photonic qubits and measurement-induced nonlinearities in linear\noptics. Both implementations have in common that their main decoherence\nmechanism is absorption in dielectric materials. The quantum theory of light in\nabsorbing media and its implications to decoherence will form the last part of\nthe lectures.",
