  Games with unawareness model strategic situations in which players'
perceptions about the game are limited. They take into account the fact that
the players may be unaware of some of the strategies available to them or their
opponents as well as the players may have a restricted view about the number of
players participating in the game. The aim of the research is to introduce this
notion into theory of quantum games. We shall focus on PQ Penny Flip game
introduced by D. Meyer. We shall formalize the previous results and consider
other cases of unawareness in the game.
