An aspect of the present invention relates to a quantum cash system and a quantum cash apparatus which can inhibit even forgery in which quantum verification information is transformed using inverse transformation data, thus improving security. In order to allow quantum cash to be validly used, a quantum cash holding apparatus (3) outputs one of the inverse transformation data and then inhibits the output of the other inverse transformation data in a verification list. This prevents the outflow of the other inverse transformation data, required for the forgery of the quantum cash.
