Practical Side-Channel Attack on Free-Space QKD Systems With Misaligned Sources and Countermeasures
Practical implementations of quantum key distribution (QKD) protocols can introduce additional degrees of freedom in the quantum states that may render them distinguishable to an eavesdropper. This is the case of QKD systems using a different laser source to generate each quantum state, which can le...
