Detection and estimation of quantum channel capacities
This thesis investigates the subject of quantum channel capacities and is composed of two parts. 1. Detecting positive quantum capacities of quantum channels Determining whether a noisy quantum channel can be used to reliably transmit qubits at a non-zero rate is a challenging problem, since it …

On the capacity of the erasure channel and the construction of an [epsilon]-randomizing map
The quantum information theory is the counterpart of the classical information theory in quantum computation, and it has raised many questions regarding the transmission and security of the information in quantum computers. This thesis studies the efficiency of such processes and contributes to two …
