  Attention to the very physical aspects of information characterizes the
current research in quantum computation, quantum cryptography and quantum
communication. In most of the cases quantum description of the system provides
advantages over the classical approach. Game theory, the study of decision
making in conflict situation has already been extended to the quantum domain.
We would like to review the latest development in quantum game theory that is
relevant to information processing. We will begin by illustrating the general
idea of a quantum game and methods of gaining an advantage over
  "classical opponent". Then we review the most important game theoretical
aspects of quantum information processing. On grounds of the discussed
material, we reason about possible future development of quantum game theory
and its impact on information processing and the emerging information society.
The idea of quantum artificial intelligence is explained.
