    • 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.

    • In a communication system, a transmitter device encrypts variable-length data having a data length corresponding to a kind of information to be transferred or a communication capacity, using a natural random number, to produce a variable-length random number sequence. Then, the transmitter device performs an exclusive OR operation per bit between the variable-length random number sequence and the information to produce transfer information, and transmits the transfer information to a receiver device. The transmitter device further transmits the variable-length data and the natural random number in an encrypted manner to the receiver device. The receiver device reproduces the variable-length data and the natural random number transmitted in the encrypted manner, and then encrypts the variable-length data using the natural random number to produce a variable-length random number sequence which is identical with the foregoing variable-length random number sequence produced at the transmitter device. Then, the receiver device performs an exclusive OR operation per bit between the thus produced variable-length random number sequence and the received transfer information to reproduce the original information.

    • According to each embodiment of the present invention, a phase-correlation can be generated between respective laser fields produced by a plurality of independent lasers. Specifically, based on a structure that first and second laser fields each having a mixed quantum state represented by a single-mode Glauber coherent state that a phase is completely indeterminate are mixed with each other and a quantum continuous measurement is performed by causing absorbers to individually cross two output quantum states, the phase-correlation can be generated between the first and second laser fields when absorption by the absorbers massively occurs in one of the two quantum states as a result of the quantum continuous measurement.
