    摘要: 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 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.

    摘要: In the method of the present invention, one of each pair of photons connected through entanglement is distributed to a transmitting station, relay stations and a receiving station. After the photons reach secure sites, such as the relay stations, a base for detecting photons is determined between adjacent sites, and then photons are detected in each site, which makes it possible to obtain a secret key used for secure information transmission between relay stations using bases coincide with each other every time. Also, in the present invention, a high-quality random number sequence serving as a secret key is automatically generated in a physical manner every time by detecting a superposition state of an entanglement and procedures corresponding to those in which a secret key itself is transmitted in a form of a quantum cryptogram are performed.
