Dear All, Just thought I'd pass on a nice demo idea from the AJP, involving participants with coloured glasses and chocolate balls replicating a quantum encryption protocol, even in the face of classical and quantum attack: American Journal of Physics, September 2006 - Volume 74, Issue 9, pp. 800-803 Karl Svozil - Staging quantum cryptography with chocolate balls The first performance of this idea took place at the Vienna University of Technology as a part of “Lange Nacht der Forschung” (Long Night of Science) event. I think I might try this out at a Quantum Information event here in Oxford soon... best, Mark -- ----------------------------------------------------------------- Mark A G Jones Nanomaterials for Quantum Information Processing Office 195.20.09 QIPIRC, Department of Materials, University of Oxford, Parks Road, Oxford OX1 3PH, UK tel: +44-1865-273700 tel direct: +44-1865-273719 fax: +44-1865-273789 e-mail: [log in to unmask] Collaboration Website: http://www.qipirc.org Group Website: http://www.nanotech.org Department Website: http://www.materials.ox.ac.uk College Website: http://www.lincoln.ox.ac.uk ----------------------------------------------------------------- ********************************************************************** 1.
