The influence of bright light on a single-photon detector has been described in a number of recent publications. The impact on quantum key distribution (QKD) is important, and several hacking experiments have been tailored to fully control single-photon detectors. Special attention has been given to avoid introducing further errors into a QKD system. We describe the design and technical details of an apparatus which allows to attack a quantum-cryptographic connection. This device is capable of… 
Light on a beam splitter: More randomness with single photons
TLDR
It is shown that a single photon source provides more randomness than even a brighter laser, which proves the advantages of true single photons versus coherent input states of light in an experimental implementation and can be adapted to microscopy and sensing.
Controlling single-photon detector ID210 with bright light
We experimentally demonstrate that a single-photon detector ID210 commercially available from ID Quantique is vulnerable to blinding and can be fully controlled by bright illumination. In quantum key
Detector-device-independent quantum key distribution
TLDR
This work demonstrates a proof-of-principle experiment of a QKD scheme that removes the need for a two-photon system and instead uses the idea of aTwo-qubit single-Photon to significantly simplify the implementation and improve the efficiency of mdiQKD in several aspects.
Controlling single-photon detector ID210 with bright light.
TLDR
It is experimentally demonstrate that a single-photon detector ID210 commercially available from ID Quantique is vulnerable to blinding and can be fully controlled by bright illumination, which can be exploited by an eavesdropper to perform a faked-state attack.

TLDR
An avalanche single-photon detector blinding attack is one of the methods for quantum hacking of quantum key distribution (QKD) systems and changes the photocount statistics and leads to the detection of an eavesdropper.
Safeguarding Quantum Key Distribution Through Detection Randomization
TLDR
The proposed combined countermeasure represents a practical and readily implementable solution against the main classes of quantum hacking attacks aimed on the single-photon detector so far, without intervening on the inner working of the devices.
On the structural stability of phase-coded quantum cryptography against detector-blinding attacks
TLDR
The paper proposes a fundamentally new method of detecting and protecting quantum cryptography systems with phase coding against the attack with avalanche detector blinding, based on diverting a part of the input signal in the receiving terminal to bypass the interferometer and deliver it to the same avalanche detectors.
Robust countermeasure against detector control attack in a practical quantum key distribution system
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 the detectors,
Inherent security of phase coding quantum key distribution systems against detector blinding attacks
TLDR
It is proved that detector blinding attack, when acts on QKD systems with phase coding, leads to a distortion of the photocounts statistics so the eavesdropper may always be detected.
Advances in quantum key distribution and quantum randomness generation
TLDR
This thesis discusses some progress in quantum key distribution and quantum randomness generation, and presents a study on reference-frame-independent protocols whose knowledge can help design more efficient protocols, and a framework to the security analysis of distributed-phase-reference protocols, which have been missing for many years.

Controlling an actively-quenched single photon detector with bright light.
TLDR
The generality of the attack and its possible applicability to eavsdropping the full secret key of all QKD systems using avalanche photodiodes (APDs) are demonstrated, and two new technical loopholes found just in one detector model suggest that this problem must be solved in general, by incorporating generally imperfect detectors into the security proof forQKD.

Single photon detectors (SPDs) based on passively quenched avalanche photodiodes can be temporarily blinded by relatively bright light, of intensity less than 1nW. A bright-light regime suitable for
Measurement-device-independent quantum key distribution.
TLDR
The results show that long-distance quantum cryptography over say 200 km will remain secure even with seriously flawed detectors, and the key generation rate is many orders of magnitude higher than that based on full device independent QKD.
Thermal blinding of gated detectors in quantum cryptography.
TLDR
It is demonstrated that the detectors in a commercial QKD system Clavis2 can be blinded by heating the avalanche photo diodes using bright illumination, so-called thermal blinding, and the detectors can be triggered using short bright pulses once they are blind.
