| 摘要 |
A quantum communication system, said system comprising: an emitter configured to send signal light pulses having a first intensity and decoy light pulses having a second intensity to a receiver, wherein information is encoded on said signal pulses; a controller configured to set the distribution of signal pulses and decoy pulses and the intensity of the signal pulse such that the maximum average secure bit rate is achieved over the range of potential drift in the decoy pulse intensity during use of the system, while maintaining a non-zero secure bit rate over the range of potential drift in the decoy pulse intensity during use of the system.
