The ability of an eavesdropper (Eve) to perform an intercept-resend attack on a free-space quantum key distribution (QKD) receiver by precisely controlling the incidence angle of an attack laser has been previously demonstrated. However, such an attack could be ineffective in the presence of atmospheric turbulence due to beam wander and spatial mode aberrations induced by the air's varying index of refraction. We experimentally investigate the impact turbulence has on Eve's attack on a free…

Mitigating the effect of atmospheric turbulence on orbital angular momentum-based quantum key distribution using real-time adaptive optics with phase unwrapping.

This work investigates the performance degradation of OAM-based QKD by infinitely long phase screen (ILPS), which offers a feasible way to study how adaptive optics (AO) dynamically corrects the turbulence-induced aberrations in real time, and simulates that real-time AO can still mitigate the impact of atmospheric turbulence on O AM-basedQKD even in the large wind velocity regime.

This study examines the HOM interference in a realistic lab environment and concludes that exceptional interference visibility can be achieved using typical commercially available optical devices and detectors, further demonstrating the applicability of the MDI-QKD protocol.

Generalized efficiency mismatch attack to bypass the detection-scrambling countermeasure.

This work shows how randomization effectively prevents the initial attack but fails to do so when Eve generalizes her attack strategy, and could be used to scrutinize a free-space quantum communication receiver against detector-efficiency-mismatch type attacks.
