Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

We present a different attack on quantum key distribution based on the idea of adaptive absorption [J. Calsamiglia et al., Phys. Rev. A (64, 043814 (2001)]. The conditional beam-splitting attack is shown to be much more efficient than the conventional beam splitting attack, achieving a performance similar to the, powerful but currently unfeasible, photon number splitting attack. The implementation of the conditional beam-splitting attack, based solely on linear optical elements, is well within the reach of current technology.
