> Abstract: We show how PerkinElmer SPCM-AQR detector module can
> be controlled by an eavesdropper using bright optical pulses, by
> exploiting an obscure flaw in the detector electrical circuit. First
> experimental results are reported. This loophole may make possible an
> attack against quantum cryptosystems that use these detectors.
