We propose and experimentally demonstrate a scheme to render the detection apparatus of
a quantum key distribution system immune to the main classes of hacking attacks in which …

Imperfect devices in commercial quantum key distribution systems open security loopholes
that an eavesdropper may exploit. An example of one such imperfection is the wavelength …

The physical imperfections of quantum key distribution systems compromise their
information-theoretic security. By exploiting the imperfections on the detection unit, an …

Device-independent quantum key distribution provides security even when the equipment
used to communicate over the quantum channel is largely uncharacterized. An experimental …

Attacks that control single-photon detectors in quantum key distribution using tailored bright
illumination are capable of eavesdropping the secret key. Here we report an automated …

The security of quantum key distribution (QKD) can easily be obscured if the eavesdropper
can utilize technical imperfections in the actual implementation. Here, we describe and …

Practical implementations of quantum key distribution (QKD) have been shown to be subject
to various detector side-channel attacks that compromise the promised unconditional …

In real-life implementations of quantum key distribution (QKD), the physical systems with
unwanted imperfections would be exploited by an eavesdropper. Based on imperfections in …

Several attacks have been proposed on quantum key distribution systems with gated single-
photon detectors. The attacks involve triggering the detectors outside the center of the …

In this work, we present a quantum key distribution protocol using continuous-variable non-
Gaussian states, homodyne detection and post-selection. The employed signal states are …
