| 1 | Frequency-multiplexed entanglement for continuous-variable quantum key distribution显示文摘Quantum key distribution with continuous variables already uses advantageous high-speed single-mode homodyne detection with low electronic noise at room temperature.Together with continuous-variable information encoding to nonclassical states,the distance for secure key transmission through lossy channels can approach 300 km in current optical fibers.Such protocols tolerate higher channel noise and also limited data processing efficiency compared to coherent-state protocols.The secret key rate can be further increased by increasing the system clock rates,and,further,by a suitable frequency-mode-multiplexing of optical transmission channels.However,the multiplexed modes couple together in the source or any other part of the protocol.Therefore,multiplexed communication will experience cross talk and the gain can be minuscule.Advantageously,homodyne detectors allow solving this cross-talk problem by proper data processing.It is a potential advantage over protocols with single-photon detectors,which do not enable similar data processing techniques.We demonstrate the positive outcome of this methodology on the experimentally characterized frequency-multiplexed entangled source of femtosecond optical pulses with natural cross talk between eight entangled pairs of modes.As the main result,we predict the almost 15-fold higher secret key rate.This experimental test and analysis of frequencymultiplexed entanglement source open the way for the field implementation of high-capacity quantum key distribution with continuous variables. | OLENA KOVALENKO YOUNG-SIK RA YIN CAI VLADYSLAV C.USENKO CLAUDE FABRE NICOLAS TREPS RADIM FILIP | 2021 | Photonics Research2021，9，12： | 3 |
