Summary
Goal subject is acquaint students basic physical principles and experimental realizations modern quantal communications technology, specially quantal distribution keys, whose safeness is guaranteed law quantal physicists. Students themselves adopts gradually foundations coherent optical communication and obtain bases quantum opticians. These foundations then apply to description quantum distribution keys with homodynním and jednofotonovým detector. At the conclusion the students pass an excursion on experimental workplace, where they have possibility to acquaint with experimental implementation of these new communications technologies.
