Abstract: A control device that determines tape reference positions having a fixed positional relationship with first origin positions based on first positions of tape feeding devices when leading ends of carrier tapes are detected and the first origin positions of the tape feeding devices immediately before leading end detection. Then, after determination of the tape reference positions, an interval between cavities is calculated based on a detection cycle of transmitted light amounts detected by light being transmitted through empty cavities. In addition, when a phenomenon, in which a detected light amount is equal to or smaller than a threshold, consecutively occurs after calculation of the interval between the cavities, it is detected that components are accommodated in the cavities.

Abstract: There is provided a quantum-key distribution method between a plurality of users or groups. A center prepares a predetermined number of entangled states consisting of qubits equal to the number of the users, and generates quantum states consisting of the qubits belonging to each of the entangled states and corresponding to each of the users. The center transmits each of the quantum states to each of the users after an authentication process. Each of the users receiving the quantum state makes public an axis used to measure each of the qubits constituting the quantum states. The number of users in each group measuring the qubits with a predetermined axis is represented by module 4. If the sum of the module 4 of each group is even, each group collects the qubit measurement results of the users and acquires each group key. Therefore, it is possible to provide a high-security quantum-key distribution method between an unspecified number of users or groups.
