The peculiar properties of quantum mechanics allow two remote parties to communicate a
private, secret key, which is protected from eavesdropping by the laws of physics 1, 2, 3, 4 …

We propose a class of attacks on quantum key distribution (QKD) systems where an
eavesdropper actively engineers new loopholes by using damaging laser illumination to …

It has previously been shown that the gated detectors of two commercially available
quantum key distribution (QKD) systems are blindable and controllable by an eavesdropper …

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 …

Quantum key distribution (QKD) promises information theoretic secure key as long as the
device performs as assumed in the theoretical model. One of the assumptions is an absence …

Security in quantum cryptography, is continuously challenged by inventive attacks,,,,
targeting the real components of a cryptographic set-up, and duly restored by new …

We control using bright light an actively-quenched avalanche single-photon detector.
Actively-quenched detectors are commonly used for quantum key distribution (QKD) in the …

Several vulnerabilities of single-photon detectors have recently been exploited to
compromise the security of quantum-key-distribution (QKD) systems. In this Letter, we report …

Quantum key distribution (QKD) is a method of realizing private communication securely
against an adversary with unlimited power. The QKD protocols proposed and demonstrated …

Quantum key distribution (QKD) allows two remote parties to grow a shared secret key. Its
security is founded on the principles of quantum mechanics, but in reality it significantly …
