Abstract
The present invention concerns a Quantum Key Distribution transmission system comprising a transmitter and a receiver, wherein the transmitter is configured to transmit a multiphoton pulse to the receiver through a trusted area that extends from the transmitter towards the receiver up to a trusted distance from the transmitter; wherein the transmitter is configured to transmit the multiphoton pulse with a transmission power such that a single-photon pulse propagates out from the trusted area up to reach the receiver.
Claims16
A Quantum Key Distribution (QKD) transmission system (2, 3) comprising transmitter (31) and a receiver (32), wherein the transmitter (31) is configured to transmit a multiphoton pulse to the receiver (32) through a trusted area (23, 33) that extends from the transmitter (31) towards the receiver (32) up to a trusted distance (D) from the transmitter (31);
- wherein the transmitter (31) is configured to transmit the multiphoton pulse with a transmission power such that a single-photon pulse propagates out from the trusted area (23, 33) up to reach the receiver (32).
A method for Quantum Key Distribution (QKD) transmission from a transmitter (31) to a receiver (32), comprising transmitting, the transmitter (31), a multiphoton pulse to the receiver (32) through a trusted area (23, 33) that extends from the transmitter (31) towards the receiver (32) up to a trusted distance (D) from the transmitter (31);
- wherein transmitting includes transmitting the multiphoton pulse with a transmission power such that a single-photon pulse propagates out from the trusted area (23, 33) up to reach the receiver (32).
