| Measurement device-independent quantum key distribution with time-dependent source side-channels | QCRYPT 2021 | J. Eli Bourassa, Li Qian, Hoi-Kwong Lo |
We identify a time-dependent passive source side-channel in common measurement-device-independent quantum key distribution implementations that rely on Faraday mirrors for stable phase modulation. We model the time-dependence of the side channel and use this information in conjunction with a recently developed numerical security proof technique based on semidefinite programming to quantify the impact on the secure key rate of the protocol. We explore the sensitivity of security to the parameters of the side channel and the choice of model for the signal. |
