    "abstract": "The relativistic quantum protocols realizing the bit commitment and distant\ncoin tossing schemes are proposed. The protocols are based on the fact that the\nnon-stationary orthogonal extended quantum states cannot be reliably\ndistinguished if they are not fully accessible for the measurement. As the\nstates propagate from the domain controlled by one of the user to the domain\naccessible for the measurements performed by the other user, they become\nreliably distinguishable for the second user. Important for the protocol are\nboth the quantum nature of the states and the existence of a finite maximum\nspeed of the signal propagation imposed by the special relativity.",
