Reply to "Avoiding the Detector Blinding Attack on Quantum Cryptography"
Lars Lydersen, Carlos Wiechers, Christoffer Wittmann +3
This is a reply to the comment by Yuan et al. [arXiv:1009.6130v1] on our publication [arXiv:1008.4593].
Low-threshold Optical Parametric Oscillations in a Whispering Gallery Mode Resonator
J. U. Fürst, D. V. Strekalov, D. Elser +4
In whispering gallery mode (WGM) resonators light is guided by continuous total internal reflection along a curved surface. Fabricating such resonators from an optically nonlinear…
Birefringence and dispersion of cylindrically polarized modes in nanobore photonic crystal fiber
T. G. Euser, M. A. Schmidt, N. Y. Joly +10
We demonstrate experimentally and theoretically that a nanoscale hollow channel placed centrally in the solid glass core of a photonic crystal fiber strongly enhances the cylindric…
Thermal blinding of gated detectors in quantum cryptography
Lars Lydersen, Carlos Wiechers, Christoffer Wittmann +3
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 using c…
Hacking commercial quantum cryptography systems by tailored bright illumination
Lars Lydersen, Carlos Wiechers, Christoffer Wittmann +3
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. So-called…
Quantum Light from a Whispering Gallery Mode Disk Resonator
J. U. Fürst, D. V. Strekalov, D. Elser +4
Optical parametric downconversion has proven to be a valuable source of nonclassical light. The process is inherently able to produce twin beam correlations along with individual i…
