Quantum Repeater Network System |
摘要 |
Provided is a quantum repeater network system that does not need any matter qubit. According to the quantum repeater network system for performing quantum communication between one transmitter/receiver and the other transmitter/receiver via transmission repeaters and reception repeaters, each of the transmission repeaters prepares quantum systems in an irreducibly entangled state, each of said quantum systems being associated with a reception repeater as a transmission destination, and transmits, to the associated reception repeater, each of the quantum systems in the irreducibly entangled state together with a quantum system entangled with the quantum system. |

1. A quantum repeater network system for performing quantum communication between one transmitter/receiver and the other transmitter/receiver via transmission repeaters and reception repeaters,
wherein a transmitter of the transmitter/receiver includes (a) a unit for transmitting quantum systems to reception repeaters as transmission destinations, wherein each of transmission repeaters includes: (b1) a unit for preparing quantum systems in an irreducibly entangled state, each of said quantum systems being associated with a reception repeater as a transmission destination; and (b2) a unit for transmitting, to the associated reception repeater, each of the quantum systems in the irreducibly entangled state together with a quantum system entangle with the quantum system, and wherein each of reception repeaters includes: (c1) a unit for receiving quantum systems transmitted by transmitters/receivers communicating with the reception repeater and by transmission repeaters communicating with the reception repeater; (c2) a measurement device for measuring the quantum systems received; and (c3) a unit for transmitting measurement outcomes to transmitters/receivers. |
