  Quantum computing is a highly abstract scientific discipline, which, however,
is expected to have great practical relevance in future information technology.
This forces educators to seek new methods to teach quantum computing for
students with diverse backgrounds and with no prior knowledge of quantum
physics. We have developed an online course built around an interactive quantum
circuit simulator designed to enable easy creation and maintenance of course
material with ranging difficulty. The immediate feedback and automatically
evaluated tasks lowers the entry barrier to quantum computing for all students,
regardless of their background.
