    • Automated characterization of single-photon avalanche photodiode 

      Ghazali, Aina; Bugge, Audun Nystad; Sauge, Sebastien; Makarov, Vadim (Journal article; Peer reviewed, 2011)
      We report an automated characterization of a single-photon detector based on commercial silicon avalanche photodiode (PerkinElmer C30902SH). The photodiode is characterized by I-V curves at different illumination levels ...

    • Controlling a superconducting nanowire single-photon detector using tailored bright illumination 

      Lydersen, Lars Vincent Van de Wiel; Akhlaghi, Mohsen K.; Majedi, A. Hamed; Skaar, Johannes; Makarov, Vadim (Journal article; Peer reviewed, 2011)
      We experimentally demonstrate that a superconducting nanowire single-photon detector is deterministically controllable by bright illumination. We found that bright light can temporarily make a large fraction of the nanowire ...

    • Controlling an actively-quenched single photon detector with bright light 

      Sauge, Sebastien; Lydersen, Lars Vincent Van de Wiel; Anisimov, Andrey; Skaar, Johannes; Makarov, Vadim (Journal article; Peer reviewed, 2011)
      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 visible and near-infrared range. This study shows ...

    • Controlling passively quenched single photon detectors by bright light 

      Makarov, Vadim (Journal article; Peer reviewed, 2009)
      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 attacking a quantum key ...

    • Full-field implementation of a perfect eavesdropper on a quantum cryptography system 

      Gerhardt, Ilja; Liu, Qin; Lamas-linares, Antia; Skaar, Johannes; Kurtsiefer, Christian; Makarov, Vadim (Journal article; Peer reviewed, 2011)
      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 relies on the physical implementation. ...
